Chart basics

Avakhada chakra in Vedic astrology

The avakhada chakra is a table of birth details found near the start of most printed kundlis. It lists the birth nakshatra and its quarter, the Moon sign, a first syllable for a name, and six traits used in marriage matching: varna, vashya, yoni, gana, nadi and rajju.

Avakhada chakra: how the API computes it

The API builds the avakhada chakra from the birth Moon. Varna and vashya come from the Moon's sign. Gana, nadi, yoni and rajju come from its nakshatra, the Moon's birth star (BD-01).

The API reads them from the same tables it uses for marriage matching. So a person's chart and their match can never disagree about their own gana or nadi. The name syllable (naamakshar) comes from the quarter (pada) of the birth nakshatra.

Some printed kundlis (birth charts) also show paya, tattva and a few other items. The API leaves these out on purpose. Several rules for them are in use, and they give different answers for the same chart (BD-02).

Get the table from POST /v1/reading/section/birth-details. That call also returns the panchang (the Hindu almanac) at the birth moment and the Hindu calendar date. The table is part of the full report on POST /v1/report as well.

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.
