Saturn (Shani) in Vedic astrology: what BPHS, Saravali and Bhrigu Sutras say, and how to read it in your chart

Saturn is the graha the classical texts are hardest on. Brihat Parashara Hora Shastra (BPHS) gives it grief to govern, makes it the servant in the planetary cabinet and, opening its account of Saturn's Dasha, calls it the vilest of the grahas. The same text makes Saturn the cause of a Raja Yoga for Taurus Lagna, gives it one of the five Mahapurusha yogas, and describes a well-placed Saturn Dasha as years of recognition, position and property. Most of what is worth knowing about Saturn sits in the conditions that separate those two readings.

This page sets out what BPHS, Saravali and Bhrigu Sutras actually say about Saturn, with chapter and sloka, where they disagree, and what this app's engine does with each rule. It is a map of rules, not a forecast about anyone. To see whether Saturn's transit puts your Moon sign in Sade Sati today, use the Sade Sati calculator; for Saturn's sign, house and dignity at your birth, the Birth Chart calculator.

Shani at a glance

BPHS Ch. 3 and Saravali Ch. 4 each list the grahas' attributes, and the modern introduction to Bhrigu Sutras adds its own. The rows mostly agree; where they differ, both readings are shown.

What Saturn signifies

BPHS Ch. 3 Sloka 12-13 gives each graha one governance: the Sun the soul, the Moon the mind, Saturn grief. Saravali Ch. 4 Sloka 1-2 repeats the scheme and the rule that goes with it, that a strong significator makes the thing it signifies strong and a weak one makes it meagre, and then adds one exception: "in the case of Saturn it is different." A strong Saturn means less of what it signifies, not more. BPHS Ch. 27 Sloka 32-33 is more guarded when it sets the strength Saturn needs: great strength in Saturn gives long life and miseries together.

BPHS Ch. 70 Sloka 1-6, listing what is judged from each graha, gives Saturn longevity, the source of one's maintenance, grief, danger and losses. Ch. 32 Sloka 31-34 makes it the karaka of two houses, the 8th and the 12th, and Sloka 22-24 reads longevity from the 8th house counted from Saturn. The modern introduction to Bhrigu Sutras calls it Ayush Karaka, the chief governor of longevity, and Sanaischara, the slow mover. These are classifications. This app computes no lifespan and times no death from any of them.

Saravali Ch. 7 Sloka 7-13 lists what Saturn is karaka for: lead, zinc and the black metals, coarse grains, servants, the poor, goods for sale and self-restraint. Sloka 14-15 gives it the region of Saurashtra. Bhrigu Sutras widens the list to land, property, mines and real estate, to masonry, pottery, plumbing and other heavy labour, and to farmers, miners and the aged. It also argues with the planet's reputation. Saturn, it says, is much maligned: what it does through restriction and delay is turn a person toward introspection and effort, and a well-placed Saturn makes someone grave, prudent, reliable and a capable organiser.

Body associations appear in every one of these texts. BPHS gives Saturn the muscles and a windy temperament; Bhrigu Sutras assigns it the teeth, bones, spleen, knees, right ear and hearing. These are reported as classification, not medical advice, and this app makes no health prediction from them.

A malefic, the second strongest, and the eldest

BPHS Ch. 3 Sloka 11 lists Saturn with the Sun, Mars, the waning Moon and the nodes as malefics, and Ch. 34 Sloka 8-10 grades them: the weak Moon, the Sun, Saturn and Mars are stronger in malefic disposition in that ascending order. So in BPHS's own ranking Saturn is the second strongest malefic, behind Mars. Ch. 3 Sloka 48 calls it the eldest graha, the one that gives the most years in the Naisargika Dasha, and Sloka 33 gives it the year where the Sun gets the half-year and the Moon the Muhurta.

In practice the label does three things. A planet joined with Saturn is, in BPHS Ch. 45 Sloka 11-18, in the Kshudhita state, the same state as a planet in an enemy's sign. A house Saturn occupies loses one Rupa of strength in BPHS's Bhava Bala (Ch. 27 Sloka 30-31, a calculation this engine does not make). And Saravali Ch. 30 Sloka 86-87 states the general rule for where a malefic sits: it harms the houses it occupies, the 6th, 8th and 12th excepted, with results running from maximum to nil according to strength, aspect and dignity.

This engine follows the same classification. It counts Saturn among its malefics, with the Sun, Mars, Rahu and Ketu, and reads Saturn's transits by the malefic rule. In its Shad Bala a planet aspected only by malefics scores nothing on the aspect component, so Saturn's three aspects count against the planets they fall on.

Dignity: Libra, Capricorn, Aquarius and Aries

Exaltation and fall

BPHS Ch. 3 Sloka 49-50 exalts Saturn in Libra, deepest at 20 degrees, and puts its fall in the seventh sign from there, Aries, deepest at the same 20 degrees. Bhrigu Sutras gives the same points and this engine stores them. The pair mirrors the Sun's: Saturn's exaltation sign is the Sun's fall and Saturn's fall is the Sun's exaltation, with the Sun's deep points ten degrees earlier in each sign. The four signs that decide most of what follows each have a page: Libra, Capricorn, Aquarius and Aries.

Two own signs, one Moolatrikona

Saturn owns Capricorn and Aquarius. BPHS Ch. 3 Sloka 51-54 says its arrangement in Aquarius is the same as the Sun's in Leo: the first 20 degrees are Moolatrikona and the rest is own sign. Saravali Ch. 5 Sloka 21-24 and Bhrigu Sutras state it directly, and Bhrigu Sutras adds that the whole of Capricorn is own sign. This engine agrees with all three: Aquarius 0 to 20 degrees reads Moolatrikona, Aquarius 20 to 30 and all of Capricorn read own sign. For the Sun in Leo the engine and the texts part company; for Saturn they do not.

Friends, enemies and the sign-by-sign verdict

BPHS Ch. 3 Sloka 55 derives natural friendship from the Moolatrikona sign: the lords of the 2nd, 4th, 5th, 8th, 9th and 12th signs from it are friends, along with the lord of the exaltation sign; the rest are enemies; a planet on both lists is neutral. Worked from Aquarius: Taurus and Libra (Venus, also the exaltation lord) and Gemini and Virgo (Mercury) make two friends. Pisces, the 2nd, belongs to Jupiter, but so does Sagittarius, the 11th, so Jupiter lands on both lists and is neutral. Mars (Aries, Scorpio), the Moon (Cancer) and the Sun (Leo) appear only on the other side and are enemies. Saravali Ch. 4 Sloka 28-29 and Bhrigu Sutras state exactly that list, and this engine uses it.

The feeling is not always returned. In the same Saravali sloka Venus counts Saturn a friend and the Sun counts it an enemy, so those two match. But the Moon has no enemies at all, Mars names only Mercury as an enemy, and Mercury's friends are the Sun and Venus. Saturn is neutral to all three, while it counts Mercury a friend and the Moon and Mars enemies.

Natural friendship is half of how a sign is graded. BPHS Ch. 3 Sloka 56 adds a temporary relationship read from the chart itself: a planet in the 2nd, 3rd, 4th, 10th, 11th or 12th sign from another is its friend there, and Sloka 57-58 combine the two. The engine's dignity function implements that combination but applies it only when it is handed the chart. The Shad Bala, planet-in-house and Mahadasha readings pass your chart, so the label you see for Saturn is the one in the fourth column, which depends on where the sign lord sits. The third column is the natural relation alone, for reference.

How much each state is worth differs by source. BPHS Ch. 3 Sloka 59-60 gives exaltation the full good effect, Moolatrikona three quarters, own sign half, a friend's sign a quarter and a neutral sign an eighth, where the engine's ladder runs 10, 10, 7.5, 6.25 and 5; the Sun page sets the two side by side. Saravali Ch. 45 describes Saturn in each state. Exalted: royal assignments and leadership over villages and towns. In Moolatrikona: of good family, wealthy and valorous. In its own sign: honourable and happy. Debilitated: adversity and pennilessness. In an enemy's sign: distress. Its one surprise is the friend's sign, where Saravali has the native depending on others for food.

Retrograde Saturn

Saturn is retrograde more than a third of the time. Run daily across 1950-2049, this engine has it retrograde on 36.6 per cent of days, in one stretch a year of 133 to 142 days. The texts pull two ways on what that means. BPHS Ch. 27 Sloka 21-23 gives retrograde motion the highest motional strength of the eight kinds it lists, and Saravali Ch. 4 Sloka 36 counts a retrograde planet strong. But Saravali Ch. 5 Sloka 39 says a retrograde malefic brings grief and aimless wandering where a retrograde benefic can confer a kingdom, and Sloka 14 records a view that a planet retrograde in its exaltation sign gives no good effect. The engine flags retrograde on every chart and transit and gives a retrograde Saturn no motional credit either way: following its own source, Saturn earns that point only in Mercury's signs, Gemini and Virgo.

Rays: a measure that ignores ownership

Saravali Ch. 36 Sloka 2 gives Saturn 5 rays at exaltation, the fewest of any graha along with Mars and Mercury, and BPHS Ch. 73 Sloka 1-2 has the same figures. Sloka 3-4 records the other school, 7 rays for every graha, which the engine uses. Either way the count depends only on the distance from the fall point (Sloka 6), so it ignores ownership: Saturn at 10 degrees of Aquarius, in its Moolatrikona, collects 2.72 rays, fewer than at 10 degrees of Leo, an enemy sign (4.28). One of Sloka 7-9's corrections is specific to Saturn: a combust planet loses all its rays, Venus and Saturn excepted. The engine applies none of those corrections and shows the base figure in the Deep Dive on your Kundali.

When and where Saturn is strong

Each line below is a rule the texts state, followed by what this engine does with it.

• Direction. BPHS Ch. 3 Sloka 35-38 makes Saturn the one graha that gains strength in the West, and Saravali Ch. 4 Sloka 35 places that in the 7th house. BPHS Ch. 27 Sloka 7 measures it from the Lagna, so it is nil in the 1st house and full in the 7th. The engine does the same: full directional strength in the 7th, none in the 1st, falling off evenly by house between.
• Time of day. Saturn, the Moon and Mars are strong at night (BPHS Ch. 3 Sloka 35-38, Ch. 27 Sloka 8-9; Saravali Ch. 4 Sloka 36). The Tribhaga rule cuts across that: Saturn gets its full share in the last third of the day, not the night (BPHS Ch. 27 Sloka 12; Saravali Ch. 4 Sloka 39). The engine credits Saturn's time strength for a night birth, judged by whether the Sun was below the horizon at the birth place, stays neutral when there is no place, and does not compute Tribhaga.
• Fortnight and course. Malefics are strong in the dark fortnight (BPHS Ch. 3 Sloka 35-38; Saravali Ch. 4 Sloka 36). In Saravali Ch. 4 Sloka 37 Saturn and the Moon take their Ayana Bala in Dakshinayana, the southern course, which BPHS Ch. 27 Sloka 15-17 computes from the planet's own southern declination. The engine holds the fortnight share at a fixed half for every planet and gives Saturn no course-based credit.
• Decanate. The texts disagree here. BPHS Ch. 27 Sloka 6 gives the neuter grahas, Saturn and Mercury, their decanate strength in the third decanate of a sign; Saravali Ch. 4 Sloka 38 gives it in the second. The engine computes neither.
• Nature. Saturn is last in natural strength in both texts (BPHS Ch. 3 Sloka 35-38, Ch. 27 Sloka 14; Saravali Ch. 4 Sloka 40): one seventh of a Rupa where the Sun gets the whole. In the engine's 20-point Shad Bala Saturn's natural share is 0.125 of 1, the lowest of the seven.
• Combustion. The engine marks Saturn combust within 15 degrees of the Sun, which over 1950-2049 is 9.1 per cent of days, about a month in every year, and a combust planet loses its position score. BPHS Ch. 47 Sloka 57-60 lists a combust Saturn among the conditions for an adverse Dasha.

BPHS Ch. 27 Sloka 32-33 sets the Shad Bala Saturn needs to count as strong at 300 Virupas, the lowest bar, shared with Mars, and Sloka 34-36 gives the two of them the same component thresholds. Those figures belong to BPHS's full Virupa computation. The Shad Bala calculator runs a simplified 20-point version from the engine's own source, so its totals cannot be compared with 300; the Vimshopaka Bala calculator gives BPHS's separate twenty-point divisional strength (Ch. 7 Sloka 9-12).

Aspects: the 3rd, the 7th and the 10th

BPHS Ch. 26 Sloka 2-5 gives every graha a full aspect on the 7th place from itself and graded partial aspects elsewhere: a quarter on the 3rd and 10th, a half on the 5th and 9th, three quarters on the 4th and 8th. Three grahas have special full aspects, and Saturn's fall on exactly the two places where everyone else has only a quarter, the 3rd and the 10th. Sloka 9-10 give Saturn its own arithmetic for the graded value, and Saravali Ch. 4 Sloka 32-33 agrees on the special aspects. This engine counts full aspects only, so Saturn aspects three houses in your chart: the 3rd, 7th and 10th from the one it occupies.

Two consequences follow from the geometry, and both can be checked on any chart. Saturn's 3rd aspect is never returned: a planet in the 3rd from Saturn has Saturn in its own 11th, and no graha has a full aspect on the 11th. Its 10th aspect is returned by one graha only: a planet in the 10th from Saturn has Saturn in its 4th, which is one of Mars's special aspects. So Saturn and Mars in that arrangement aspect each other fully, and any other planet there is aspected without aspecting back.

Saravali Ch. 29 reads the aspect of each graha on Saturn, grouped by the lord of Saturn's sign. Jupiter's aspect is favourable in every group: a king's minister in the signs of Mars (Sloka 25-30), charitable and well liked in Venus's (31-36), trusted in the king's circle in Mercury's (37-42), lands, houses and friends in Cancer (43-48), chief and trustworthy in Leo (49-54), a king, minister or army chief in Jupiter's own signs (55-60), famous and long-lived in Saturn's (61-66). The Sun's aspect, which as a full aspect means the Sun opposite Saturn, reads badly in most groups, with exceptions in the signs of Mars (prosperity through agriculture) and of Jupiter (wealth and a name through children).

BPHS Ch. 42 Sloka 16-18 turns one Saturn aspect into a named combination. The Sun in the 2nd house aspected by Saturn is read as a strain on wealth, and the same Sun free of Saturn's aspect as riches and fame; Saturn in the 2nd aspected by the Sun gets the first reading too. Mars and Saturn together in the 2nd are read the same way unless Mercury aspects them, which reverses it. This engine's dosha list flags all three, worded as financial caution and not as a fixed loss.

What Saturn rules from your Lagna

Saturn owns two neighbouring signs, so it always rules two adjacent houses. BPHS Ch. 34 names its role for each rising sign, and the Yoga Karaka fold on your Kundali reproduces those lists. Confirm your rising sign with the Lagna calculator.

The pattern follows Ch. 34's general rules. Sloka 2-7: a trine lord is auspicious, the lords of the 3rd, 6th and 11th give evil effects, and a malefic that owns an angle stops being inauspicious, which Sloka 14 says holds fully only when it owns a trine as well. Sloka 13 adds that one graha owning both an angle and a trine is specially a Yoga Karaka. Saturn meets that test for two Lagnas: Taurus, where it rules the 9th and 10th, and Libra, where it rules the 4th and 5th. The Lagna-by-Lagna slokas name it as the cause of Raja Yoga only for Taurus; for Libra they call it auspicious and give the Raja Yoga to the Moon and Mercury. The commentator in Bhrigu Sutras and Advanced Predictive Astrology both call Saturn the Yoga Karaka for Libra. The engine follows the sloka as written: its Yoga Karaka list has Saturn for Taurus only, and its auspicious list has it for Libra.

Aries shows the limit of the rule from the other side. Saturn rules an angle there, the 10th, but its other house is the 11th, so BPHS classes it a malefic and says its conjunction with Jupiter, lord of the 9th, produces no yoga despite the angle-and-trine pairing. Bhrigu Sutras' introduction puts the whole matter more broadly: Saturn favours those born under the signs of Venus and is hard on those born under the signs of Mercury. BPHS does not go that far. For Gemini and Virgo it leaves Saturn unclassed.

One chart shows how these lenses can disagree. For midnight beginning 15 August 1947 at New Delhi, a moment this engine's own notes use as a worked example, the Lagna is Taurus, so Saturn is the Yoga Karaka. The same Saturn sits in Cancer, an enemy sign, in the 3rd house, within 15 degrees of the Sun. The engine scores it 3.96 out of 20 in Shad Bala, rates it weak, and reads its Mahadasha as challenging. Lordship says what Saturn is for in that chart; dignity and strength say how well it can deliver. Neither cancels the other.

Sasa Yoga and Saturn's other yogas

BPHS Ch. 75 Sloka 1-2 and Saravali Ch. 37 Sloka 2 give five grahas a Mahapurusha yoga each when in own sign or exaltation in an angle from the Lagna. Saturn's is Sasa. BPHS Sloka 20-22 describes the Sasa native as valorous and wise, at home in forests and mountains, alert to an opponent's weak points, and a ruler over several regions. Saravali Sloka 8-10 adds an army chief, skilful in every assignment and devoted to his mother, and, less flatteringly, crafty and quick to fault others. Both texts also give body measurements, palm marks and an age at death, none of which is repeated here. The engine detects Sasa when Saturn is exalted, in Moolatrikona or in its own sign and in the 1st, 4th, 7th or 10th house, and describes it as resilient, strategic and self-reliant.

Whole-sign houses make the yoga easy to bound. Saturn in Libra or Capricorn is in an angle only for the four movable Lagnas (Aries, Cancer, Libra, Capricorn); Saturn in Aquarius only for the four fixed ones (Taurus, Leo, Scorpio, Aquarius). A Gemini, Virgo, Sagittarius or Pisces Lagna can never have Sasa Yoga. Saturn spends a little over a quarter of its time in those three signs (26.4 per cent of days across 1950-2049 in this engine), and for all of that time four rising signs in twelve qualify. So the yoga is shared by a large slice of everyone born in the same two or three years, the point what a yoga in your chart means makes about weighing any yoga. The Yogas calculator lists it when your chart has it.

Saturn appears in several other combinations the engine checks. In BPHS Ch. 41, Saturn in the 5th house in its own sign with the Sun and Moon in the 11th (Sloka 5), the Moon in Cancer in the 5th with Saturn in the 11th (Sloka 8), and Saturn in the Lagna in its own sign joined or aspected by Mars and Jupiter (Sloka 15) are all wealth yogas. Around the Moon, Saravali Ch. 13 reads Saturn in the 2nd from it (Sunapha) as skilful, respected in one's town and wealthy, and in the 12th (Anapha) as a leader who keeps commitments (Sloka 12-19). Around the Sun, Saravali Ch. 14 is less kind to the Vesi and Vasi yogas Saturn forms, while granting wealth in the first and a head for business in the second (Sloka 3-9). BPHS Ch. 36 Sloka 29-30 also has Kusuma Yoga, for a fixed Lagna with Saturn in the 10th, Venus in an angle and the Moon in a trine with a benefic; this engine does not check for it.

Saturn in the twelve signs

Saravali Ch. 29 reads Saturn in each sign without reference to house. It is a severe chapter. The table keeps its temperament, livelihood and fortune lines and leaves out its sexual lines, its disease lines and its harsher character verdicts.

Set against the dignity table, the readings follow it only in part. Libra and Capricorn read as well as exaltation and own sign should. Aquarius, the Moolatrikona sign, gets one of the chapter's harshest entries, and the two signs of Jupiter, which the engine grades as merely neutral, get two of its best. Bhrigu Sutras' introduction sides with Saravali: Saturn is beneficial in its own sign, when exalted, or in the signs of Jupiter. So does BPHS Ch. 47 Sloka 57-60, which lists Sagittarius and Pisces among the placements that turn Saturn's Dasha favourable. A Saturn in Sagittarius or Pisces reads neutral in this app and better than that in all three texts.

Because Saturn stays in a sign for two to three years, these readings are shared by everyone born in that span. They describe a cohort before they describe a person. The house, which changes roughly every two hours as the Lagna moves, is what makes Saturn individual.

Saturn with another graha

Saravali Ch. 15 gives the effect of two planets in one house. Its six Saturn pairs, with the harsher lines left out:

• With the Sun (Sl. 7): a metallurgist, virtuous and mindful of his duties; the sloka's family predictions are not repeated. Within 15 degrees this is also a combust Saturn.
• With the Moon (Sl. 12): well liked by the public, a keeper of horses and elephants, but under the control of others and without wealth.
• With Mars (Sl. 16): a metallurgist, clever with illusion, quarrelsome; one of the chapter's hardest pairs.
• With Mercury (Sl. 19): debts and pride, but an able poet, expert, well-spoken and fond of travel.
• With Jupiter (Sl. 21): heroic, wealthy, famous, the head of a city, an assembly or an association; the one plainly favourable pairing.
• With Venus (Sl. 22): skilled in working wood, a painter or sculptor, fond of wandering, an owner of livestock.

Sloka 23 adds that each result rises or falls with the vargas the two planets occupy. The pattern matches Saturn's friendships only loosely: its two natural friends, Mercury and Venus, give mixed readings, and the best one belongs to Jupiter, a neutral.

Saturn in the twelve houses

Each house has its own page, built from Bhrigu Sutras' Saturn chapter, Saravali Ch. 30 and the BPHS chapter on that house. The shape of the whole is this. Bhrigu Sutras and its commentator repeat two points: Saturn in its own sign or exaltation in an angle forms Sasa Yoga, and Saturn does unusually well in the 3rd, 6th and 11th, the upachaya houses where a malefic is welcome. Saravali Ch. 30 agrees on the 3rd (courageous, charitable, intelligent; Sloka 76) and the 6th (conquers many enemies; 79), and is warmest about the 10th (wealthy, learned, a minister, judge or leader of a town; 83) and the 11th (lasting riches, courage, free of sickness; 84). Its Lagna reading turns entirely on dignity: equal to a king in own sign or exaltation, a hard and slow start otherwise (74).

The 8th is the one open disagreement. Bhrigu Sutras gives Saturn there a long life, longer still in own sign or exaltation, and its commentator calls Saturn the exception among malefics in that house. Saravali Ch. 30 Sloka 81 reads the same placement as a short life and failed undertakings. Both are reported as what the texts say. This app times nothing from either.

This app's planet row for Saturn prints a favourable sentence when Saturn is exalted, in Moolatrikona, in its own sign or in a friendly sign, and is not in the 6th, 8th or 12th; otherwise a testing sentence. Two effects of that rule are worth knowing. A Saturn in Sagittarius or Pisces, being neutral, always gets the testing sentence. And a Saturn in the 6th gets it too, even in its own sign, although the 6th is one of the houses the texts read best for it. The favourable sentences, paraphrased from Bhrigu Sutras:

The house pages: Saturn in the 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, 10th, 11th and 12th.

Karakas: the 8th, the 12th and the Atma Karaka

BPHS uses Saturn as a significator in three ways. As a house karaka (Ch. 32 Sloka 31-34) it has the 8th and the 12th. As a fixed point of reference, Sloka 22-24 read longevity from the 8th counted from Saturn, and Ch. 7 Sloka 39-43 add the 12th from it. The third way depends on the chart: Ch. 32 Sloka 3-8 rank the seven grahas by how far each has travelled through its sign, and the one furthest in is the Atma Karaka. Saturn holds that role when it has the highest degree. The Char Karakas calculator shows which role your Saturn holds, and the Karakamsa calculator follows the Atma Karaka into the Navamsa. Saravali Ch. 6 Sloka 1-2 uses the word differently again: planets in own sign or exaltation in angles become mutual karakas, and its own example is Saturn in Libra for a Cancer Lagna.

Saturn's Ashtakavarga: 39 points

In Saturn's own Ashtakavarga each of eight contributors (the seven grahas and the Lagna) marks the places, counted from itself, that are good for Saturn. BPHS Ch. 66 Sloka 59-60 lists them, 39 in all. Sloka 39-42 counts the other side, the places each contributor marks as bad, and the two lists are exact complements: 57 bad marks, eight marks per place.

The engine's table, which its code first took from a different book, used to differ from the sloka in two cells: it credited Venus's 5th place where BPHS credits Mercury's 12th. Since October 2026 it follows BPHS, whose good-mark and bad-mark lists agree on both, and matches the sloka in all 96 cells. The total is 39 either way, but in a given chart one point can land in a different sign. If your Saturn Ashtakavarga here differs by a point from another program's, check those two cells first. The pattern is clear in either version: the 6th and 11th places collect 15 of the 39 points, and Saturn itself gives points only from the 3rd, 5th, 6th and 11th.

BPHS Ch. 70 Sloka 43-44 puts the table to work: Saturn's transit through signs holding more good marks in its own Ashtakavarga is favourable, and through signs holding more bad marks is not. (BPHS calls the good marks rekhas and the bad ones dots; this app calls the good ones bindus. The arithmetic is the same.) The app's transit reading uses a different measure, the combined Sarvashtakavarga of the house against your chart's own average. The Ashtakavarga calculator returns Saturn's own table house by house, so the BPHS rule can be applied by hand.

Timing: nineteen years of Vimshottari

In Vimshottari, Saturn rules nineteen of the 120 years (BPHS Ch. 46 Sloka 15), after Jupiter's sixteen and before Mercury's seventeen; only Venus has more. Counting the lords from Krittika as Sloka 12-14 direct, Saturn owns Pushya, Anuradha and Uttara Bhadrapada, and a Moon in any of the three begins life in Saturn's Mahadasha with at most nineteen years of it left. What a Mahadasha is has the arithmetic, the Saturn Mahadasha has its own page, and the nakshatras are Pushya, Anuradha and Uttara Bhadrapada.

The same proportion divides a nakshatra's arc: in the Nakshatra Sub-Lord calculator Saturn's sub is 2 degrees 6 minutes 40 seconds wide in every nakshatra, 13 degrees 20 minutes times 19/120. How the sub-periods divide covers the level below the Antardasha, which matters here more than anywhere: the shortest sub-period in Saturn's Mahadasha is eleven months long.

What the texts expect of the period

BPHS Ch. 47 Sloka 5-6 gives the test for every Dasha: favourable if at its start the lord is in the Lagna, exalted, in its own or a friendly sign; unfavourable in the 6th, 8th or 12th, in debilitation or in an enemy's sign. For Saturn, Sloka 53-56 describe the strong case (exalted, own sign, Moolatrikona or a friendly sign, in its own or exalted Navamsa, in the 3rd or 11th house) as recognition by the government, name and fame, success in education, a high position, property and children. Sloka 57-60 describe the reverse for a Saturn in the 6th, 8th or 12th, debilitated or combust: separation from the father, distress in the family and trouble with authority. Its poison, weapon and imprisonment lines are not repeated here. The same slokas then add an escape clause: a Saturn joined or aspected by a benefic, in an angle or a trine, or in Sagittarius or Pisces, gives position and comforts instead.

Saravali's Dasa chapter, written for its own Moola Dasa scheme, is earthier. A favourable Saturn Dasa brings gains through pulses, sesame and iron, leadership over villages and a lasting position for one's people (Ch. 41 Sloka 48-49); an adverse one brings loss of conveyances, enmity, separation from family and lassitude (Sloka 50-51). Its sub-periods inside Saturn's Dasa (Ch. 42 Sloka 48-53) track Saturn's relationships closely: Mercury, Jupiter and Venus read as fortune, high position and fame; the Sun, the Moon and Mars read as loss, separation and leaving home. BPHS Ch. 57 conditions each sub-period instead on the sub-lord's own dignity and its position counted from Saturn: an angle, a trine or the 11th from the Dasha lord helps, the 6th, 8th or 12th from it hurts. Ketu is the exception, read as difficult even when well placed (Sloka 16-18). BPHS attaches a remedy and a maraka line to each sub-period; neither is repeated here.

Two timing rules sit inside the period. Ch. 47 Sloka 3-4 says a graha in the first decanate of its sign shows its results at the start of its Dasha, the second in the middle, the third at the end, and reverses the order for a retrograde graha, which Saturn is in more than a third of charts. And Ch. 57 Sloka 24-27 reads the Venus sub-period better when Jupiter or Saturn is also favourable by transit: Dasha and transit are meant to be read together.

In the app, the dasha reading applies Ch. 47 Sloka 5-6 as written. It grades Saturn's Mahadasha good for an exalted, Moolatrikona or own-sign Saturn, neutral for a friendly or neutral sign, and challenging for an enemy sign, debilitation or the 6th, 8th or 12th house. It does not apply the benefic-aspect clause or the Sagittarius-or-Pisces clause. Its favourable theme for Saturn is hard-won but durable results through sustained effort; its testing theme is a demanding, restrictive period of delay and pressure, as distinct from outright loss. The Vimshottari Dasha calculator finds when yours runs, and the Timing feature shows the dated windows.

Saturn in other dasha systems

The Alternate Dashas calculator shows the six computed systems. Numerology keeps a separate clock: in Advanced Vedic Numerology's Mahadasha scheme Saturn rules 8 years of a 45-year cycle, and the Numerology Dasha calculator runs it from your Mulank. When the two clocks disagree, the disagreement is itself the signal.

Transits: two and a half years a sign

Bhrigu Sutras gives Saturn 29 and a half years to circle the zodiac and about two and a half years in a sign, the slowest of the grahas Indian astrology recognises. This engine labels a Saturn transit at 913 days. The real stays are less even. Counted over one full circuit by this engine, from Saturn's entry into Libra in late 2011 to its next in 2041, they run from about 2.1 years (Gemini, Cancer) to about 2.9 (Virgo). About half the sign changes come in threes: a first entry, a retrograde step back into the old sign for a few months, and a final entry.

Sade Sati

Sade Sati is Saturn's passage through the 12th, 1st and 2nd signs from the natal Moon. Advanced Predictive Astrology (Vol. II, p. 311) gives that definition and notes that it comes round once in about thirty years. This engine applies it by sign and names three phases: rising (Saturn in the 12th from the Moon), peak (in the Moon's own sign) and setting (in the 2nd). The Sade Sati calculator needs only your birth date, reports the phase, and says so when the Moon could be in either of two signs on that date. Your Moon sign is the starting point, which your rashi is not your star sign explains.

Three details in the same source change how the rule applies. First, it exempts a chart where Saturn is a Yoga Karaka and well placed with benefic association; the engine applies no exemption. Second, it gives a degree-based version: Sade Sati begins when Saturn is 45 degrees behind the natal Moon and ends 45 degrees past it. That agrees with the sign rule only for a Moon at 15 degrees of its sign. For a Moon in the first degree, the sign rule starts when Saturn is about 31 degrees behind and ends about 59 degrees ahead, which at Saturn's pace moves each end by more than a year. Third, it records a North Indian school that confines the difficult part to one or two of the three segments, depending on the Moon sign.

Seven and a half years is a round figure. Summing the time Saturn actually spends in the three signs over the engine's 2011-2041 circuit gives anything from about six and a half years (a Gemini Moon) to a little over eight (a Libra Moon). Nor is the period always one unbroken block: when Saturn steps back out of the 12th sign in retrograde, the calculator's verdict switches off for those months and on again.

The engine describes the period as intensified pressure and restructuring, a time to consolidate, and explicitly not an omen. The source is blunter about strain at work, delay and low spirits, but its own case list cuts both ways: it names public figures who took high office during a Sade Sati as well as ones who lost it. It also says the period makes little difference to someone born with the Moon and Saturn together, and that once Saturn moves into the 3rd from the Moon a new chapter of some twenty-two years opens.

Ardha Ashtama Sani, Ashtama Sani and the general transit rule

The same book names two shorter transits (p. 313): Ardha Ashtama Sani, Saturn in the 4th from the Moon, read as a strain on domestic peace because the 4th is the house of contentment, and Ashtama Sani, Saturn in the 8th. The engine reports both through the Ashtama Sani calculator, worded as periods that call for patience at home and care with new risk. While Saturn is in Pisces, Sade Sati runs for Aquarius (setting), Pisces (peak) and Aries (rising) Moons, Ardha Ashtama Sani for Sagittarius and Ashtama Sani for Leo. Each moves on one sign when Saturn does.

The second row deserves a second look. By the general rule a malefic in the 2nd from the Moon is well placed, so the Gochar calculator reads Saturn there as favourable in the very months the Sade Sati calculator calls the setting phase. Both rules come from the engine's one source, and the app shows both without netting them. Advanced Predictive Astrology draws the line elsewhere: Saturn is good in the 3rd, 6th and 11th from the Moon, a period of gain in the 10th, and most intense over the Moon itself (p. 311). All three agree on the 3rd, 6th and 11th and on the 1st.

Two more rules on that page are counted from natal Saturn, not the Moon: Saturn crossing the 9th sign from its birth position is read as a rise in fortune, and its exact opposition to its birth position as a time when important events tend to come. By the 29.5-year circuit the opposition falls near ages 15 and 44. The app computes neither. The Daily feature shows where Saturn is now.

Saturday, the hora and the divisions

Saravali Ch. 7 Sloka 1-3 gives the weekdays to the seven grahas in order from the Sun, which makes the seventh, Saturday, Saturn's, and rules the first hora of each day by that day's lord. The Hora calculator builds the sequence for any date and place. In the divisional charts, BPHS Ch. 7 Sloka 13-16 says Saturn, with the Moon and Venus, shows its effects most in the Moon's Hora, which the Hora (D2) calculator reports for every graha. In the Trimshamsa Saturn owns five degrees of every sign, 5 to 10 degrees of an odd sign and 20 to 25 of an even one (BPHS Ch. 6 Sloka 27-28), as the Trimshamsa (D30) calculator shows. And BPHS Ch. 3 Sloka 66-70 derives Gulika from Saturn's share of the day or night divided in eight; this app does not compute Gulika.

Saturn and the number 8

Advanced Vedic Numerology's table of numbers and planets gives 8 to Saturn, and this app's numerology engine names Saturn as the ruler of Mulank 8, which it calls the Strategist. The link is a mapping, not a calculation from the chart: someone born on the 8th, 17th or 26th need not have a strong Saturn, and a strong Saturn says nothing about the birth date. Number 8 in numerology covers that side, Mulank, Bhagyank and Life Path how the numbers are found, and the Numerology feature what the app does with them.

Checking Saturn in your own chart

1. 1.Cast the chart with the Birth Chart calculator and note Saturn's sign, degree, nakshatra and house, and whether it is retrograde or combust. Sign, degree, retrograde and combustion need only the date, since Saturn moves about two arcminutes a day; the house needs the time and place, as what a missing birth time costs explains.
2. 2.Read the dignity off the sign table. If Saturn is in Aquarius, note whether its degree is under 20. If it is in Sagittarius or Pisces, remember the texts read it better than the app's neutral label.
3. 3.Find the two houses it rules from your Lagna in the BPHS Ch. 34 table, and whether your Kundali's Yoga Karaka fold lists it.
4. 4.Mark the three houses it aspects, the 3rd, 7th and 10th from its own, and the planets in them. Then find what aspects Saturn: any planet opposite it, Mars when Saturn is in the 4th or 8th from Mars, Jupiter when Saturn is in the 5th or 9th from Jupiter.
5. 5.Check the Yogas calculator for Sasa Yoga and the wealth yogas, remembering which Lagnas can hold Sasa at all.
6. 6.Check its strength in the Shad Bala calculator: directional strength peaks in the 7th, and a night birth adds time strength.
7. 7.Look at its Ashtakavarga row and its role among the Char Karakas.
8. 8.Last, timing: when Saturn's Mahadasha and Antardashas fall in the Vimshottari Dasha calculator, and where it transits now from your Moon in the Sade Sati and Gochar calculators.

Your full Kundali collects all of these in one place, and every book cited here is listed on the Sources page.

Common misreadings

• "Saturn is the worst planet, so a prominent Saturn is bad." BPHS ranks Mars above it in malefic strength, makes it the Raja Yoga planet for Taurus Lagna and auspicious for Libra and Aquarius, and gives it a Mahapurusha yoga. Saravali and Bhrigu Sutras both read it well in the 3rd, 6th, 10th and 11th houses.
• "A strong Saturn means more hardship." Saravali Ch. 4 makes Saturn the exception to the rule that a strong significator magnifies what it signifies. BPHS Ch. 27 is more guarded, pairing great strength with long life and burdens together. The dignity chapters of both read a weak Saturn worse, not better.
• "Sade Sati lasts exactly seven and a half years and is uniformly bad." Its length ran from about six and a half to a little over eight years by Moon sign in the engine's last circuit, its edges depend on whether you count by sign or by degree, and the source that defines it lists people who rose during it.
• "Saturn is in its own sign in Aquarius, so every reading is good." Dignity says yes. Saravali's sign reading for Aquarius is among its harshest, and the ray count puts Saturn at 10 degrees of Aquarius below Saturn at 10 degrees of Leo. They are different measures.
• "Retrograde Saturn is weak." Saturn is retrograde on more than a third of days. BPHS gives retrograde motion its highest motional strength, Saravali reads a retrograde malefic as restless, and this engine gives it no credit either way.
• "Saturn aspects that planet, so they aspect each other." Only in the 7th. Saturn's 3rd aspect is never returned, and its 10th is returned by Mars alone.
• "My Saturn sign describes me." It describes everyone born over two to three years. The house, the lordship from your Lagna and the aspects are what narrow it to one chart.
• "The Saturn Mahadasha is nineteen hard years." BPHS Ch. 47 makes the outcome depend on Saturn's sign, house, company and aspects at birth, and both Dasha chapters read the Mercury, Jupiter and Venus sub-periods, almost half of the nineteen years, as capable of going well.
• "Every book makes Saturn the Yoga Karaka for Libra." Modern commentary does. BPHS Ch. 34's own sloka names it for Taurus and calls it auspicious for Libra, which is how this app lists it.

The other grahas: the Sun, the Moon, Mars, Mercury, Jupiter, Venus, Rahu and Ketu. The houses Saturn is most tied to: the 7th, where it gains directional strength; the 8th and the 12th, its house-karaka roles; and the 10th, where Saravali reads it best.

Is Saturn a benefic or a malefic in Vedic astrology?

A natural malefic in BPHS Ch. 3 Sloka 11 and Saravali Ch. 4 Sloka 9, and the second strongest after Mars in BPHS Ch. 34 Sloka 8-10. Its role in a given chart depends on the Lagna: BPHS Ch. 34 makes it the Raja Yoga planet for Taurus and auspicious for Libra and Aquarius.

Where is Saturn exalted, debilitated and in Moolatrikona?

Exalted in Libra, deepest at 20 degrees; debilitated in Aries, deepest at 20 degrees (BPHS Ch. 3 Sloka 49-50). It owns Capricorn and Aquarius, and the first 20 degrees of Aquarius are its Moolatrikona (Sloka 51-54). This app uses the same points.

Which planets are Saturn's friends and enemies?

Friends: Mercury and Venus. Neutral: Jupiter. Enemies: the Sun, the Moon and Mars. BPHS Ch. 3 Sloka 55 derives this from Aquarius, and Saravali Ch. 4 Sloka 28-29 and Bhrigu Sutras state it directly.

Which houses does Saturn aspect?

The 3rd, 7th and 10th from the house it occupies. Every graha has the 7th; the 3rd and 10th are Saturn's special full aspects (BPHS Ch. 26 Sloka 2-5; Saravali Ch. 4 Sloka 32-33).

How long is the Saturn Mahadasha, and how do I know when mine runs?

Nineteen years in Vimshottari (BPHS Ch. 46 Sloka 15). When it runs depends on your Moon's nakshatra at birth; the Vimshottari Dasha calculator finds it from your birth date.

What is Sade Sati, and am I in it?

Saturn transiting the 12th, 1st or 2nd sign from your natal Moon. The Sade Sati calculator checks it from your birth date and names the phase. With Saturn in Pisces it applies to Aquarius, Pisces and Aries Moons.

Is Sade Sati always seven and a half years?

No. The figure is three signs at about two and a half years each. Saturn's real stay in a sign varies, and by this engine the three signs together took between about six and a half and a little over eight years in the 2011-2041 circuit, depending on the Moon sign.

What is Sasa Yoga, and can my chart have it?

Saturn in its own sign or exaltation in the 1st, 4th, 7th or 10th house (BPHS Ch. 75 Sloka 1-2). With whole-sign houses only the movable and fixed Lagnas can have it: Aries, Cancer, Libra and Capricorn from Saturn in Libra or Capricorn, and Taurus, Leo, Scorpio and Aquarius from Saturn in Aquarius.

Is a retrograde Saturn bad?

The texts do not agree. BPHS Ch. 27 gives retrograde motion the highest motional strength; Saravali Ch. 5 Sloka 39 reads a retrograde malefic as grief and wandering. Saturn is retrograde on about 37 per cent of days, so it is an ordinary condition. This app flags it and gives it no strength credit either way.

Do I need my birth time to read Saturn?

Not for its sign, degree, dignity, retrograde state or Sade Sati, which need only the date. You need the time and place for its house, the houses it rules and aspects, its directional strength and Sasa Yoga.

Why does the app call Saturn in the 2nd from my Moon favourable during Sade Sati?

Two rules overlap there. The general transit rule the engine follows reads a malefic in the 2nd from the Moon as well placed; the Sade Sati rule counts the same sign as its setting phase. The app shows both. Advanced Predictive Astrology's own favourable list for Saturn is the 3rd, 6th and 11th.

Does the app suggest remedies for Saturn or Sade Sati?

No. BPHS Ch. 57 prescribes recitations and charity for each sub-period and Bhrigu Sutras lists gems; this app carries no remedies, gemstones or rituals for any placement or transit.
