What it does

Builds the Saptamsa (D7): each sign split into seven parts of about 4°17′ with planets placed in the matching signs.

Why it matters

Tradition reads D7 for children and descendants, as a detail layer under the 5th house.

How it is worked out

  1. Each sign is divided into seven equal slices.
  2. For odd signs the count starts from the same sign; for even signs it starts from the 7th sign from it.
  3. The slice number gives the planet's D7 sign.

How to read your result

  • Check the 5th house of D7 and the planets in it.
  • Compare with the main chart: the tradition looks for consistency between D1 and D7.

What it cannot tell you

Time-sensitive, and a traditional symbol only. It says nothing about fertility or whether you will have children.
