Dhaiya in Vedic astrology

Dhaiya: how the API computes it
Dhaiya is Saturn's time in the 4th or the 8th sign counted from the birth Moon. Each lasts about two and a half years. That is where the word, meaning two and a half, comes from.
Saturn in the 4th sign is called kantaka shani or ardha shani. Saturn in the 8th is called ashtama shani. The API reports both and keeps them apart from sade sati, Saturn's seven and a half years around the Moon sign. That is because they are different periods with different names (SS-02).
Take someone with a Libra Moon. Saturn in Capricorn would be in the 4th sign from it, and Saturn in Taurus in the 8th. Saturn often turns back across a sign boundary. So the API dates every crossing, and a dhaiya period can show a short break in the middle (SS-03).
POST /v1/sadesati returns the dhaiya periods with their start and end dates, together with the sade sati periods. It also says whether one is running on the date you ask about.

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.
