In short
The Navamsa, or D9, is the divisional chart made by cutting each 30-degree sign into nine parts of 3°20' and mapping each part to a sign. BPHS lists it among the sixteen vargas and reads the spouse from it. This app computes it for every planet and, when the birth time is known, for the Ascendant.
What the term means
Navamsa is Sanskrit for "ninth part". It is one of the vargas, the divisional charts built from the birth chart (the D1, or Rashi chart). The "D9" label simply means "division by nine". Each sign of 30 degrees is cut into nine equal parts of 3°20', and every part is assigned a sign. A planet's Navamsa sign is the sign of the part its longitude falls in.
Where the term comes from
BPHS Ch. 6 Sl. 2-4 names sixteen divisions of a sign, and the Navansh (the translation's spelling) is the sixth. Sl. 12 gives the rule: for a movable sign the count starts from the sign itself, for a fixed sign from the 9th sign from it, and for a dual sign from the 5th. Ch. 7 Sl. 1-8 then assigns each division a subject and reads "spouse from Navansh". Ch. 7 Sl. 17-19 places the Navamsa in the six-chart Shad Varga set and gives it a Vimshopak weight of 5 there, second only to the Rashi chart's 6.
How this app computes it
- The part number is the degree within the sign divided by 3°20', rounded down (parts 1 to 9).
- The starting sign follows BPHS Ch. 6 Sl. 12: movable signs (Aries, Cancer, Libra, Capricorn) from themselves, fixed signs from the 9th, dual signs from the 5th. The count then moves forward one sign per part.
- When the D9 sign equals the D1 sign the planet is flagged vargottama.
- A Navamsa Lagna, and with it whole-sign D9 houses, exists only when the Ascendant is known, which needs a birth time (see when the birth time is unknown).
A small illustration
Take the chart for 19 January 1985, 11:14 IST, New Delhi. The engine places Jupiter at Capricorn 2.09: Capricorn is movable, so the count starts at Capricorn and the first part stays there, which makes Jupiter vargottama. Mercury at Sagittarius 16.62 is in the fifth part of a dual sign; the count starts at Aries (the 5th from Sagittarius) and lands on Leo. Saturn at Scorpio 2.64 is in the first part of a fixed sign, so it starts and stays at Cancer, the 9th from Scorpio. The Ascendant, Pisces 23.04, gives a Navamsa Lagna of Capricorn.
A small window
A Navamsa part is 3°20' wide, so a planet near a boundary, and above all the Ascendant, can change D9 sign with a small error in the birth time. Treat a D9 reading as only as firm as the time it was cast from.

What it needs
Date, time and place
That is more than this article asks for - it only ever takes a date, and sometimes a time, and never a name or a birth place. So this one runs on its own page, which asks for exactly what it needs and stores none of it.
