The Bengali year for a given Gregorian year: Pohela Boishakh and the solar new year, the twelve Sankrantis, Durga Puja and the rest of the autumn sequence, Kali Puja, Bhai Phonta, Jagaddhatri Puja and the pan-Indian festivals as Bengal observes them.
Everything is computed live for the coordinates you pass rather than read from a fixed table. The lunar festivals are found by tithi and then resolved to the civil day on which they are actually kept, using the time of day each observance requires — sunrise for some, midday for others, midnight for Maha Shivaratri — so the dates match what a Bengali panchang would print for that town.
Send `year` with `latitude`, `longitude` and `timezone_as_float`. The response is `{year, events}`, where events is a list of `{name, date}` in date order and `date` is a plain YYYY-MM-DD local civil date. Compare with /api/astro/assamese_calendar/, which shares much of this festival set but adds the Bihus and the solar Assamese observances.
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.
