Sakat Chauth
6 January 2026

Sakat Chauth is Magha Krishna Chaturthi — the Chaturthi of the krishna fortnight of Magha. It is kept after sunset, so the date is the day that tithi is running pradosh, the hour and a half following sunset.

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.
