Panchangam API
Free, no key, CORS open. Every value is computed with the Swiss Ephemeris on the Lahiri ayanamsha at that city's own horizon, and the day runs sunrise to sunrise.
Endpoints
/api/v1/today/{city}.json
Today for one city.
/api/v1/day/{city}/{YYYY-MM-DD}.json
One named day.
/api/v1/range/{city}.json?from=YYYY-MM-DD&days=31
Up to 366 days.
/api/v1/cities.json
The 18 cities with coordinates.
/api/v1/festivals.json
Festival dates, each marked published or not.
/api/v1/meta.json
Field order, name tables, range.
Times are integers
Every time is minutes from IST midnight of that date. A value above 1440 means the following day, so a tithi ending at 1531 ends at 01:31 the next morning. No timezone parsing, no ambiguity.
Two things to respect
A time is only meaningful with its city. Rahu kalam in Chennai is not rahu kalam in Delhi — every value here is computed for one town's own horizon, and quoting one for another is simply wrong.
Festivals carry published: false when the date is computed but
not asserted: either unchecked against the printed almanacs, or genuinely
contested between traditions. Govardhan Puja 2026 is contested. Please do not
render those as settled dates.
