The D10 (Dasamsa) chart: reading career and public life
The D10 (Dasamsa) is a divisional chart that splits each sign into ten parts and recasts the planets. It supplements the D1 to read work, profession and public activity in detail.

How it is built
Each 30° sign is divided into ten 3° parts. By Parashara's rule, odd signs count from the same sign and even signs from the ninth sign from it.
Why birth time precision matters
With 3° parts, the D10 Lagna changes on average about every 12 minutes, so a few minutes' error can change it.
Reading the D10
- The D10 Lagna and 10th house: approach to work and public role

- Where the Dasha planet sits in the D10: the active work area of that period
D1, D9 and D10
The D1 is the foundation; the D9 adds partnership and inner strength, the D10 career. GenesisCore calculates divisional charts when a birth time is given and limits them without one.
