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 20 October, so this year it lands 11 days earlier.

How was this date computed?

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

Maha Navami 2027 - Date and How It's Fixed

Maha Navami in 2027

Maha Navami falls on 9 October 2027, a Saturday in 2027. In 2026 it fell on 20 October, so this year it lands 11 days earlier.

What Maha Navami is

The ninth of Navratri, and its culmination - kanya pujan and the havan are kept on this day, the day before Dussehra.

How this date was worked out

The rule: Navami tithi of the Shukla paksha in purnimanta Ashwina, 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.
