Why does the date change every year?

Hindu festivals are fixed by the lunar month and tithi, which don't line up with the Gregorian calendar. The date therefore drifts each year, and shifts further in a year carrying an intercalary (adhika) month. In 2027 it falls on 14 September, 11 days earlier than this year.

How was this date computed?

Chaturdashi tithi of the Shukla paksha in purnimanta Bhadrapada, prevailing at sunrise. Computed from the sidereal (Lahiri) panchang for New Delhi.

Anant Chaturdashi 2026 - Date and How It's Fixed

Anant Chaturdashi in 2026

Anant Chaturdashi falls on 25 September 2026, a Friday in 2026. In 2027 it falls on 14 September, 11 days earlier than this year.

What Anant Chaturdashi is

The tenth and last day of Ganeshotsav, when the immersions are done. Ganesh Chaturthi opens the festival on the fourth; this closes it on the fourteenth.

How this date was worked out

The rule: Chaturdashi tithi of the Shukla paksha in purnimanta Bhadrapada, prevailing at sunrise. The date is derived from the panchang - the same computation that drives this site's daily pages. Note that the day is fixed by the tithi running during the observance window, not the one at sunrise; that is why several festivals land on a day whose sunrise tithi is something else entirely.

Regional variation

These dates are computed for New Delhi and follow the north-Indian (purnimanta) convention. Tamil, Bengali and Kerala traditions differ on several festivals, and a tithi boundary falling near a window edge can shift the day for a distant city. Check a local panchang before committing to a fast or an event.
