Panchang yoga in Vedic astrology

The panchang yoga is one of the five parts of the Hindu calendar day. It comes from adding the longitudes of the Sun and the Moon: each 13 degrees 20 minutes of the sum is one of 27 yogas, from Vishkambha to Vaidhriti. It is a different thing from a yoga in a birth chart.

Panchang yoga: how the API computes it

The panchang yoga is one of the five parts of the daily panchang (the Hindu almanac). It is not the same thing as a yoga in a birth chart. The API adds the sidereal longitudes of the Sun and the Moon, their places measured against the stars. Then it divides the sum into steps of 13 degrees 20 minutes.

Each step is one of 27 yogas, from Vishkambha to Vaidhriti (PA-02). The Sun and the Moon both move, so the yoga changes about once a day, but not at a fixed hour. That is why the API gives the yoga with its end time.

The response for a full day lists each change from one sunrise to the next. Some yogas, such as Vyatipata and Vaidhriti, are seen as difficult for new starts. Others are seen as gentle.

Do not mix this term up with the 97 chart yogas that POST /v1/yogas returns. POST /v1/panchang returns the yoga for a birth moment. GET /v1/panchang/daily and GET /v1/panchang/month return the yoga running at sunrise and when it ends.

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.
