Divisional charts (vargas)

Dwadasamsa (D12) in Vedic astrology

Dwadasamsa (D12) cuts every sign into 12 equal parts of 2°30′ 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: parents.

Dwadasamsa: how the API computes it

The dwadasamsa, D12, splits each sign into 12 parts of 2 degrees 30 minutes. So there is one part for each of the 12 signs inside every sign. A planet takes the sign of the part it lands in.

Tradition reads this chart for parents. So a reading about the father or the mother can look here after the 4th and 9th houses of D1, the birth chart. The API gives parents as the use in the signifies field.

POST /v1/chart/D12 returns the ascendant (rising sign) and every planet with the sign and house. The rulebook lists where its count starts and how it steps (VG-02, VG-03). Each part is only 2.5 degrees wide, so the Moon crosses several parts in a single day.

Take care with the Moon's place in this chart when the birth time is rounded to the hour. Tell your user when it is. For a short reading, check which planets are strong in both D12 and D1.

Name only the ones that agree. A planet strong in only one of them gives a weaker signal.

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.
