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 ten 3° parts; odd signs (Aries, Gemini, ...) count from the sign itself and even signs (Taurus, Cancer, ...) from the 9th sign from it, following Parashara. 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, and all 800 D10 placements match those computed separately from the Swiss Ephemeris positions.

FAQ

What is the Dasamsa (D10)?
A divisional chart (varga) made by dividing each sign into ten parts. Jyotish uses it to look closely at career, public role and recognition, read together with the 10th house of the birth chart (D1).
Can I calculate it without a birth time?
The D10 Lagna changes about every 12 minutes on average, so it needs an accurate birth time. The Moon's D10 changes every 5 to 6 hours. The D10 signs of the Sun to Saturn usually stay the same even if the time is a little off.
How is the D10 sign worked out?
Each sign is split into ten 3° parts. Odd signs count from the sign itself, even signs from the 9th sign from it. For example, 0°–3° Taurus falls in Capricorn and 3°–6° Taurus in Aquarius.
Does the D10 alone show the right career?
The D10 refines career themes and is traditionally read with the 10th house of the D1, its lord and the Dasha periods. This tool shows the placements accurately and explains how each is commonly read.
Is my birth data stored?
No. Nothing is stored or sent; everything runs in your browser. Shared links contain only the D10 signs of the Lagna, Sun and Saturn.
