How the navamsa (D9) is calculated
Each sign of 30° is divided into nine navamsas of 3°20′. The counting starts from a different sign depending on the kind of sign the planet is in:
| Planet in a… | Signs | First navamsa starts from |
|---|---|---|
| Movable (chara) sign | Aries, Cancer, Libra, Capricorn | The same sign |
| Fixed (sthira) sign | Taurus, Leo, Scorpio, Aquarius | The 9th sign from it |
| Dual (dvisvabhava) sign | Gemini, Virgo, Sagittarius, Pisces | The 5th sign from it |
Then count the parts in zodiac order. A Moon at 21°02′ Taurus is in the 7th part (between 20°00′ and 23°20′). Taurus is fixed, so counting starts from the 9th sign, Capricorn: the 7th sign from Capricorn is Cancer, so the Moon’s navamsa is Cancer. Each navamsa is also one pada (quarter) of a nakshatra, which is why the D9 and the nakshatra padas line up exactly. Step-by-step, with more examples: how to calculate a navamsa chart by hand.
How the dashamsa (D10) is calculated
Each sign is divided into ten parts of 3°. In an odd sign (Aries, Gemini, Leo, Libra, Sagittarius, Aquarius) the counting starts from the same sign; in an even sign (Taurus, Cancer, Virgo, Scorpio, Capricorn, Pisces) from the 9th sign from it. A Sun at 14°30′ Leo is in the 5th part; Leo is odd, so count five signs from Leo: Sagittarius.
What the D9 and D10 are read for
The navamsa is read for marriage and partnership, and to judge a planet’s real strength: a planet strong in the D1 but weak in the D9 gives less than it promises. The dashamsa is read for career, status and achievement, usually together with the 10th house and its lord in the birth chart. Both are read from their own lagna, so an accurate birth time matters.

Frequently asked questions
What is the D9 (navamsa) chart?
The navamsa is the divisional chart made by dividing each sign into nine parts of 3°20′. Brihat Parashara Hora Shastra treats it as the most important chart after the birth chart: it is read for marriage and for the real strength of each planet.
What is the D10 (dashamsa) chart?
The dashamsa divides each sign into ten parts of 3° each. It is read for career, status and public achievement.
Do I need my exact birth time?
Yes, for the lagna of the D9 and the D10: the navamsa lagna changes about every 12 to 15 minutes and the dashamsa lagna about every 12 minutes. The planets’ D9 and D10 signs need less precision, except for the Moon, which changes navamsa about every 6 hours.
What does vargottama mean?
A planet is vargottama when it occupies the same sign in the birth chart (D1) and the navamsa (D9). The texts count it as strong, much like a planet in its own sign.
Why is my D9 different from another website?
Usually because of the ayanamsa or the birth time. We use the Lahiri ayanamsa and historical time zones (including Bombay and Calcutta time). A planet near the edge of a navamsa (every 3°20′) can move into the next one with a different ayanamsa or a few minutes’ difference in the birth time.
