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 2026 it fell on 24 June, so this year it lands 11 days earlier.

How was this date computed?

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

Ganga Dussehra 2027 - Date and How It's Fixed

Ganga Dussehra in 2027

Ganga Dussehra falls on 13 June 2027, a Sunday in 2027. In 2026 it fell on 24 June, so this year it lands 11 days earlier.

What Ganga Dussehra is

The descent of Ganga, kept ten days into Jyeshtha Shukla. A river bath is the whole observance, so the date follows the sunrise tithi.

How this date was worked out

The rule: Dashami tithi of the Shukla paksha in purnimanta Jyeshtha, 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.
