Combination yogas

The exact windows during a year when one of twenty-three auspicious or inauspicious day-combinations is in force. These yogas are formed by coincidence rather than by planetary position: a particular weekday falling together with a particular tithi, and for some of them a particular nakshatra as well. Tripushkara and Dwipushkara treble and double the result of whatever is begun in them; Sarvartha Siddhi and Amrit Siddhi are broadly auspicious; Vish, Hutashan, Mrityu and Dagdha are the opposite. Eight of them — tripushkara, dwipushkara, sarvartha_siddhi, amrit_siddhi, siddha, naasha, sudha and halaahal — combine tithi, weekday and the Moon's nakshatra. The remaining fifteen, whose names begin 'vt_' or which are named for the weekday-and-tithi pairs (kulika, samvarta, karkacha, dagdha, vish, hutashan, sheela and so on), use weekday and tithi only. Send `year`, `yoga` and the place. The response is `{year, yoga, rows}` where rows is a list of `{start, end}` ISO timestamps. The windows are continuous intervals cut at every weekday boundary, the way a panchang prints them, rather than whole days — which is the difference between this endpoint and the sunrise-only day-level view in /api/astro/panchanga_yogas/, where short occurrences can be missed.

Content-Type: application/json

Request fields

Field	Type	Required	Notes
latitude	number (double)	required	Latitude of the place, in decimal degrees. Positive is north, negative is south. Example: 26.9124 for Jaipur, 40.7128 for New York. Minutes and seconds are not accepted - convert first.
longitude	number (double)	required	Longitude of the place, in decimal degrees. Positive is east, negative is west. Example: 75.7873 for Jaipur, -74.0060 for New York. Note the sign: a missing minus puts New York in China.
timezone_as_float	number (double)	required	UTC offset of the place, in hours, as a decimal. Example: 5.5 for India (UTC+05:30), -5 for New York in winter, 5.75 for Nepal. This is NOT validated against date_time - if the two disagree you get a successful response for the wrong moment, so derive both from the same source. Use the offset in force on that date, not today's: a summer birth in a country with daylight saving needs the summer offset.
year	integer	required	Year of birth as a number, e.g. 1990. Four digits. min 1800 · max 2400
yoga	string	required	`tripushkaradwipushkarasarvartha_siddhiamrit_siddhisiddhanaashasudhahalaahalvt_siddharatnakurvt_amritvt_mrityu`
