Divisional charts (vargas)

Saptamsa (D7) in Vedic astrology

Saptamsa (D7) cuts every sign into 7 equal parts of about 4.29° each. It maps each part to a sign of its own, building a separate chart from the same birth moment. It is one of the 16 divisional charts, and the API names its use as: children and progeny.

Saptamsa: how the API computes it

The saptamsa, D7, splits each sign into 7 parts of about 4.29 degrees. The part a planet sits in sets its D7 sign. Tradition reads it for children and for the family line.

The signifies field says children and progeny, which means a person's descendants. POST /v1/chart/D7 returns the ascendant (rising sign) and every planet with the sign and house in this chart. Seven does not divide 30 into a round number. So the parts are hard to guess by eye, and a hand calculation is easy to get wrong. That is a good reason to let the API do the counting (VG-02, VG-03). It uses the start sign and step the rulebook lists for each chart.

A planet only has to move about four degrees to land in the next part. The Moon does that in a few hours. So the Moon's place in D7 is the part most affected by an uncertain birth time.

For a reading on children, compare D7 with the 5th house of D1, the birth chart. Also compare it with the putrakaraka, the Jaimini planet for children, from POST /v1/jaimini.

How we check the numbers

Every value here starts from planet positions worked out from NASA JPL planet data (DE440). We test them against NASA JPL Horizons, NASA's planet position service. On 25,571 positions from 1850 to 2149, the Sun and planets agree within 0.001 arc seconds. The Moon agrees within 0.011. On 2,000 random birth charts, the rising sign agrees with Swiss Ephemeris within 0.004 arc seconds. An arc second is 1/3,600 of a degree. A practicing astrologer reviews the rules behind these answers. See how we test.
