Transits
Sade sati in Vedic astrology
Sade sati is the seven and a half years Saturn spends passing over the birth Moon. It covers three signs: the one before the Moon's sign, the Moon's sign and the one after. Each of its three phases lasts about two and a half years. Saturn circles the zodiac in about 29.5 years, so sade sati comes back about every 30 years.

Sade sati: how the API computes it
Sade sati runs while Saturn is in the sign before the birth Moon, the Moon's own sign, and the sign after it. POST /v1/sadesati returns each sade sati as three dated phases: rising, peak and setting (SS-01). Saturn often moves back into a sign for a while.
The API dates each crossing, including those, so a phase can appear more than once (SS-03). The response says whether sade sati is running on the as_of date. It also gives the dates of the next one.
The two shorter Saturn periods called dhaiya are reported separately, because they are not sade sati (SS-02). Remedy text for the period is in the reading sections. The API does not claim a past-life cause for it.

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.
