Karwa Chauth 2026: The Computed Date, Tithi and Muhurat

By Dr. R.P. Sharma, Vedic astrologer since 1979 · timings computed on real sidereal positions

Karwa Chauth 2026 falls on Thursday, 29 October 2026. The governing tithi — Kartika Krishna Chaturthi, the fast broken at moonrise — runs from 29-10-2026 01:07 IST to 29-10-2026 22:11 IST, computed from the ephemeris with the Lahiri ayanamsa, the way a Panchang actually derives it. The observance follows moonrise.

Delhi moonrise: 19:11 IST — the fast concludes with the sighting after this.

How the day is kept

The nirjala vrat runs sunrise to moonrise; the evening puja precedes the sighting of the Moon, and the fast is completed when the Moon is seen and offered arghya.

Why the tithi window matters more than the date

A Hindu festival is not a civil date; it is a tithi caught at a particular quality of time — moonrise here. When the tithi straddles two days, the rule decides the day, which is why two neighbouring calendars sometimes disagree while both cite the same sky. The window printed above is the actual astronomy; the rule applied to it is the tradition. Together they give you the answer the forwards never explain. For the method itself, see our muhurat & festivals guide.
