How it is calculated

Positions are geocentric apparent ecliptic longitudes from Astronomy Engine (MIT), converted to sidereal by removing nutation and the Lahiri ayanamsa. Rahu and Ketu use the mean lunar node. Each sign is split into nine parts of 3°20′, counted continuously from Aries (equivalent to the traditional rule: fire signs start from Aries, earth from Capricorn, air from Libra, water from Cancer). Checked against Swiss Ephemeris 2.10 at 80 instants and places between 1900 and 2100: the Lagna and the planets other than the Moon agree within 15 arcseconds, the Moon within about 1 arcminute and the nodes within 1 arcsecond, with all 800 D1 and D9 sign placements identical.

FAQ

What is the Navamsa (D9)?
A divisional chart (varga) made by dividing each sign into nine parts. In Jyotish it is the most important chart after the birth chart (D1), used for partnership, inner values and checking the strength of planets.
Can I calculate it without a birth time?
The D9 Lagna changes about every 13 minutes on average, so it needs an accurate birth time. The Moon's D9 changes about every 6 hours. The D9 signs of the Sun to Saturn usually stay the same even if the time is a little off.
What does vargottama mean?
A graha (or the Lagna) in the same sign in D1 and D9. Its themes are often read as expressing consistently in both charts. It happens in the first, middle and last part of each sign.
Why might other software give a different result?
Near a boundary, results can differ with another ayanamsa or with the true rather than the mean node for Rahu and Ketu. This tool uses Lahiri and the mean node, and flags placements close to a boundary.
Is my birth data stored?
No. Nothing is stored or sent; everything runs in your browser. Shared links contain only the D9 signs of the Lagna, Moon and Venus.
