When is Karwa Chauth?

Change city

Timings on this page are computed for Doha.

The whole table below is recomputed for the city you pick. That is not cosmetic: an observance decided at moonrise, such as Karwa Chauth, can genuinely fall on a different day in two cities, and the moment the fast ends differs by more than an hour across India.

Moonrise in Doha

29 Oct, 19:38

The fast ends at moonrise — 19:38 in Doha.

That figure belongs to Doha and to nowhere else. Moonrise swings by well over an hour between the east and the west of the country on the same evening, which is far more than sunrise does, so a single national moonrise time — the thing most pages print — is wrong almost everywhere it is read. Change the city above and this number, and sometimes the date itself, changes with it.

The two instants above are the astronomy and are not in dispute. The day is an interpretation of them: this observance is decided at moonrise, so it belongs to the day whose moonrise the tithi carries — not simply to the day the tithi begins.

Muhurat · Doha

Karwa Chauth muhurat

This observance ends at moonrise rather than inside a window.

Moonrise is an instant, not a span, so there is no window to intersect. The moonrise time for Doha is given above — and it belongs to Doha and nowhere else, because moonrise swings by well over an hour between the east and the west of India on the same evening.

Auspicious windows that day

Windows usually worked around

These are the spans classical muhurta sets aside for beginnings. They are descriptions of a convention, not warnings: the observance is kept on its day regardless, and nothing here needs to be bought, corrected or remedied.

Every window above is computed for Doha on Thursday, 29 October 2026, from that day's sunrise, sunset and the following sunrise. The Vedic day runs sunrise to sunrise, so a window whose clock time falls after midnight still belongs to the date named above rather than to the one the wall clock has turned over to.

Karwa Chauth across five years

Two years back, this year, and two ahead. Past years are kept rather than dropped so you can check the engine against a calendar you already have.

Every row is computed for Doha from the same ephemeris, not looked up. Sunrise decides which day a tithi names, and sunrise differs across India by more than an hour, so a date computed for Delhi can be a day out elsewhere.

Why calendars disagree about this date

There is no single authority that settles a Hindu festival date, and the divergence is genuine rather than sloppy. Three causes account for almost all of it.

1. A tithi rarely starts at sunrise. One that is running at the deciding moment on two days — or on none — is claimed by both days under different rules.
2. Month reckoning. North India runs purnimanta, the south and west amanta. The same dark fortnight carries different month names in the two, so an observance defined as "krishna X of month Y" can land a full lunation apart.
3. Which moment decides. Most vratas belong to the day whose sunrise carries the tithi, but not all: this one is decided at moonrise. Almanacs that apply the sunrise rule to everything move several festivals by a day.

So this page shows its working. If your pandit or your family almanac gives a different day, the instants above will usually show you exactly why — and that is more useful than a date asserted without one.
