What is the Dashamsa or D10 chart?

The tenth divisional chart. Each sign is divided into ten parts of 3° and each part is mapped to a sign, giving every planet a second position. It is read for profession, standing and the conditions of working life.

How is the D10 calculated?

Each sign is cut into ten parts of 3°. For an odd sign the parts are counted from that sign itself; for an even sign they are counted from the ninth sign after it. That asymmetry is part of the classical definition.

Can the D10 tell me which job I will get?

No. It refines the conditions and character of working life — independence, authority, visibility, steadiness. A specific role is not something the method produces.

Is the D10 more important than the 10th house?

They are read together. The 10th house and its lord in the birth chart set the frame; the D10 refines it. Neither replaces the other.

Can I use the D10 without an exact birth time?

Only partly. In our benchmark over 143 charts, a fifteen-minute error changed the D10 ascendant in 99.3% of them, while D10 planet signs changed in only 7.7%. Rely on the planets, not the ascendant or houses.

Why does my D10 differ on another website?

Usually the ayanamsa, or a different Dashamsa method — more than one is in use. We use Lahiri, the Mean node and the classical Parashari rule above, and state them on every report.

What is my Dashamsa (D10) chart?

This builds your Dashamsa — the tenth divisional chart, read for profession and public standing. Each 30° sign is cut into ten parts of 3°; from an odd sign the parts are counted from that sign itself, from an even sign from the ninth sign after it. You get the D10 ascendant and its lord, every planet's D10 house, and any planet exalted, in its own sign or debilitated in the D10.

What this calculator does

It takes each planet's longitude, divides the sign it occupies into ten parts of 3°, and maps the part it falls in to a Dashamsa sign: counted from the sign itself for an odd sign (Mesha, Mithuna, Simha…), and from the ninth sign after it for an even one (Vrishabha, Karka, Kanya…). The D10 ascendant is derived the same way from your rising degree, and house 1 of the chart below is the sign it lands in.

This is the identical D10 our Career report reads, produced by the same engine function. The ascendant lord and the exalted, own-sign and debilitated planets shown here are the same D10-native dignities the report's Dashamsha section is written from, so a free chart here and a paid report can never quietly disagree.

How to read what it gives you

The 10th house of the birth chart says what area of life a career belongs to; the D10 is read to refine it. Look first at the D10 ascendant and where its lord sits, then at planets that are exalted or in their own sign in the D10 — these are read as carrying weight in the working life — and at any that are debilitated, which are read as giving their results with more effort.

A D10 does not name a job title, and nothing in the classical method produces one. What it supports is a reading of conditions: independent or employed, public or behind the scenes, under authority or holding it. A reading that names a profession from the D10 alone has gone past the method.

Why the birth time matters so much here

A Dashamsa part is 3° wide, which the ascendant crosses in about twelve minutes. We measured this over 143 real charts: shifting the birth time by fifteen minutes changed the D10 ascendant in 99.3% of them, and by a single minute in 12.6%.

The planets are far steadier. The same fifteen-minute shift moved at least one planet to a different D10 sign in only 7.7% of charts, and most often it was the fast-moving Moon. So if your birth time is approximate, read the D10 planet placements and dignities, and treat the D10 ascendant and its houses as provisional.
