Panchanga
asterwise_get_panchanga
Panchanga for one date at a location: the limbs at sunrise plus every tithi, nakshatra, yoga and karana of the panchanga day (sunrise to next sunrise). Each comes with ISO start and end times and kshaya/vriddhi flags. Also returns sunrise, sunset, moonrise and moonset; Sun and Moon rashi; lunar month (amanta and purnimanta, with Adhik months); Vikram, Shaka and Gujarati samvat; ritu and ayana; and the day's timings (Rahu Kaal, Gulika, Yamaganda, Abhijit, Brahma Muhurta, Durmuhurta, Varjyam, Amrit Kaal, Bhadra with residence, Panchaka, Pradosh, Nishita).
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
location | object | yes | For tools that need location but not birth time. Required fields: date, lat, lon. Optional fields: timezone, response_format. |
What it covers
The top-level tithi, vara, nakshatra, yoga and karana are the limbs at sunrise. A tithi that starts after sunrise and ends before the next one (kshaya) appears in data.tithis flagged is_kshaya; a tithi that holds two sunrises is flagged is_vriddhi on both days. Times are ISO 8601 local time with offset. data.yoga is the Panchanga Yoga (Sun+Moon), unrelated to natal yogas.
