Vimsamsa (D20) in Vedic astrology

Vimsamsa (D20) is one of the 16 divisional charts. It divides each sign into 20 parts of 1°30′ and gives each part a sign, which makes a new chart. The API describes its use as: spiritual practice. POST /v1/chart/D20 returns the sign and house of the ascendant and each planet in it.

Vimsamsa: how the API computes it

The vimsamsa, D20, splits each sign into 20 parts of 1 degree 30 minutes. Each part has a sign, and that sign becomes the planet's place in D20. Tradition reads it for spiritual practice: worship, devotion and the way a person relates to a faith.

The signifies field says spiritual practice. POST /v1/chart/D20 returns the ascendant (rising sign) and every planet with the sign and house in this chart. Its start sign and step are in the rulebook (VG-02, VG-03). It is one of the charts with smaller parts.

Read it with the main chart beside it, not alone. Take a planet that is strong in D1 and also well placed in D20. It gives a fuller picture than one that is strong only in D20.

Each part is just 1.5 degrees. So the birth time has to be reliable before this chart means much. A rounded time is enough for D1, but not always for D20. So show your user which time you used.

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.
