Dussehra
20 October 2026

Dussehra is Ashwina Shukla Dashami — the Dashami of the shukla fortnight of Ashwina. It is kept in the afternoon, so the date is the day that tithi is running aparahna, the fourth of five equal parts of daylight.

Computed from the Moon’s elongation with the Swiss Ephemeris, sidereal, Lahiri ayanamsa. A tithi begins and ends at a real minute rather than at midnight, which is why the moment above decides the day — and why the same tithi read at a different hour can name a different date.
