Navamsa Calculator (D9)
Divisional charts do not create new planets. The same planets at the same degrees — the sign is simply cut into smaller parts and read again. Which is why a D9 only makes sense alongside the D1, never on its own.
What this calculator tells you
This builds your Navamsa (D9) chart — the divisional chart most used for marriage and for judging a planet’s real strength. In the tradition it ranks second only to the birth chart itself.
How the calculation works
Each sign is divided into nine equal parts of 3°20’. Whichever part a planet falls in determines its navamsa sign. Where the count begins depends on the sign’s type: movable signs count from themselves, fixed signs from the ninth from them, and dual signs from the fifth.
How to read the result
A planet that looks strong in D1 but weakens in D9 has its strength questioned by the tradition. Conversely, a planet in the same sign in both D1 and D9 is vargottama — held to be particularly strong. For marriage, the 7th house of the D9 and its lord are examined.
Common questions
How accurate must the birth time be for D9?
Very. The Moon crosses a 3°20’ segment in about six hours, but the Ascendant crosses one in roughly 13 minutes — so a small error changes the D9 Ascendant.
What is the 64th navamsa?
The 64th navamsa counted from the birth navamsa — the tradition treats it as a sensitive point. It is derived from the same 3°20’ division.
Is the D9 a separate chart?
No, it is a second layer of the same chart. D1 shows the event, D9 its root. They are read together, not one instead of the other.
