Jaimini Char Dasha

Computes Jaimini Char Dasha — a sign-based dasha system from the Jaimini school of astrology. Returns mahadasha and antardasha periods starting from the ascendant (Lagna), with the current active mahadasha and antardasha highlighted. Method: K.N. Rao, as in his own dated case notes. The sequence runs forward when the 9th sign from the Lagna is savya (Aries, Taurus, Gemini, Libra, Scorpio, Sagittarius) and backward otherwise; period years count to the sign lord (savya forward, apasavya backward) minus one, 12 for the lord in its own rashi, with no year added or taken off for an exalted or debilitated lord (JHora's K.N. Rao option adds/subtracts one). Scorpio and Aquarius count to the co-lord outside the sign, or with both outside to the one with more planets, then the one further advanced. With cycles 2 or 3, every cycle repeats the first cycle's years. Antardashas are 12 equal parts (each as many months as the mahadasha has years); K.N. Rao: they run forward or backward by the 9th sign from the mahadasha sign (the same rule the Lagna uses), starting from the next sign, and the mahadasha sign's own antardasha comes last. Request JSON follows BirthInput plus cycles (1–3): name, date (YYYY-MM-DD), time (HH:MM, required), either location or latitude/longitude/timezone, ayanamsa.

namestring

Person name associated with the birth record

datestring required

Birth date in YYYY-MM-DD format

Birth time in HH:MM 24-hour format. Required: this endpoint has no sunrise fallback.

latitudenumber nullable

Latitude. Required if location not provided.

longitudenumber nullable

Longitude. Required if location not provided.

timezonestring nullable

IANA timezone. Required if location not provided (unless utc_offset is given). For dates before the zone adopted a standard time, the birthplace's local mean time (longitude / 15 hours) is used.

utc_offsetstring nullable

Optional explicit UTC offset of the birth time, as ±HH:MM or ±HH:MM:SS (e.g. '+04:51:31' for Bombay mean time). Overrides the offset timezone would give. Use it when the birth record states the offset, or for historical local times the IANA database cannot represent.
