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.

How was this date computed?

Amavasya tithi of the Krishna paksha in purnimanta Magha, prevailing at sunrise. Computed from the sidereal (Lahiri) panchang for New Delhi.

Mauni Amavasya 2027 - Date and How It's Fixed

Mauni Amavasya in 2027

Mauni Amavasya falls on 6 February 2027, a Saturday in 2027.

What Mauni Amavasya is

The silent new moon of Magha, and the principal bathing day of the Magha season. The observance is a river bath kept in silence - maun - rather than a puja with a muhurat.

How this date was worked out

The rule: Amavasya tithi of the Krishna paksha in purnimanta Magha, 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.
