Planets (grahas)

Saturn (Shani) in Vedic astrology

Saturn (Shani in Sanskrit) is one of the nine grahas. It rules Capricorn and Aquarius, is exalted in Libra and is debilitated in Aries. It is the slowest of the visible planets, taking about 29.5 years to go around the zodiac. It stands for discipline, delay and hard work, and its transit over the Moon sign is sade sati. Its main period in the Vimshottari dasha lasts 19 years.

Saturn: how the API computes it

POST /v1/planets returns Saturn with its sign, degree, house, nakshatra (birth star) and dignity (how well it is placed in its sign). For John Doe, Saturn is at 26 degrees of Sagittarius, in house 4 and the nakshatra Purva Ashadha. It is retrograde, and its dignity is neutral.

Saturn is exalted anywhere in Libra (CH-02), and its exact high point is 20 degrees of Libra (SB-02). In Aquarius, the first 20 degrees are its mulatrikona, a strong place just below exaltation. The rest of Aquarius and all of Capricorn are its own signs (CH-04).

Saturn aspects (casts its influence on) the 7th house from itself. It also aspects the 3rd and the 10th (AS-03). It is always a natural malefic, a planet tradition treats as harsh (CH-14).

Saturn is combust within 15 degrees of the Sun (CH-07). It spends about two and a half years in each sign. When it turns retrograde near the edge of a sign, it can cross that edge three times.

The API dates every crossing (TR-06). POST /v1/sadesati returns sade sati, Saturn's seven and a half years over the signs around the birth Moon. It returns the two shorter dhaiya periods on their own.

In shadbala, the six-part strength score, Saturn needs 5 rupas to count as strong.

What the API reference says

Each line is quoted from the reference page of the endpoint named above it.

  • POST /v1/planets · Planet positions and the ascendantplanetary_war lists any pair of Mars, Mercury, Jupiter, Venus and Saturn within 1 degree of each other (graha yuddha).
  • POST /v1/ashtakavarga · Ashtakavarga: strength points for each signThere are eight contributors: the seven planets from the Sun to Saturn, plus the ascendant.
  • POST /v1/upagrahas · Upagrahas: Gulika, Mandi, the kaala velas and the Dhoomadi pointsThe Sun's part gives Kaala, the Moon's Paridhi, Mars's Mrityu, Mercury's Ardhaprahara, Jupiter's Yamakantaka, Venus's Kodanda and Saturn's Gulika.
  • POST /v1/special-lagnas · Special lagnas, the yogi point, Jaimini lords and dagdha signsSaturn, Rahu and Ketu are never returned: where one of them wins a stage, it is named nominal and graha is the 6th planet from it instead, with the other counting convention in disputed.

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.
