D10 Dashamsa Chart: Calculate It Before Reading Career
Calculate D10 using 3° parts and the odd/even starting rule. Compare two examples and keep public-work symbolism separate from career guarantees.
Overview
D10 Dashamsa divides a natal sign into ten 3° parts. Odd natal signs count from themselves; even signs count from their ninth sign, inclusively. Its traditional public-work domain is a reading context, not a promise of promotion, salary or professional status.

How do I calculate a D10 sign?
Determine the part from the degree within the sign: 0°–3° is first, 3°–6° second, and 9°–12° fourth. For an odd natal sign begin there; for an even natal sign count nine signs including itself to find the start.
Then count the part number forward, including that start. Do not confuse the ninth-sign starting offset with a D9 calculation. D10 and D9 use different segment widths and different rules even when the same planet happens to reach the same sign.
Gemini and Taurus at eleven degrees
Gemini 11° lies in part four. Gemini is odd, so Gemini, Cancer, Leo, Virgo yields D10 Virgo. Taurus 11° also lies in part four, but Taurus is even: its inclusive ninth sign is Capricorn.
Counting Capricorn, Aquarius, Pisces, Aries gives D10 Aries for the Taurus input. These deliberately paired examples expose the parity branch. Neither derived sign specifies a job; a public-work reading must still distinguish lagna, house ruler, occupant and the D1 context.
How can I use D10 for a career question?
Begin with a concrete question such as role responsibilities or the difference between daily service and public reputation. Rao Table 11 groups D10 with career, action and society. That vocabulary can organize reflection, but qualifications, applications and workplace evidence decide real opportunities.
Recalculate possible D10 ascendants across an uncertain birth-time interval. A 3° division does not correspond to one fixed number of clock minutes at every location. If its house layout changes, withhold precise house-based conclusions and use the birth-time guide before proceeding.
