Karva Chauth 2026 falls on Thursday, October 29 in India. For North America specifically, some panchang calculations place the observance a day earlier, on Wednesday, October 28, since the relevant Chaturthi tithi may already be prevailing at moonrise there a day sooner local time. Check which date your family’s local panchang or community follows, since sources genuinely differ on this point, the same way festival dates can shift by a day for other reasons.
Approximate moonrise times
Based on published panchang calculations for the 2026 observance:
- New York: around 7:32 PM local time
- Toronto: around 7:36 PM local time
- London: around 5:52 PM local time
- Dubai: around 7:58 PM local time
- Delhi, for reference: around 8:18-8:29 PM IST
These are approximate; actual moonrise can vary by a few minutes depending on your exact location and the calculation source. London stands out because late October sunsets come early there (before 5 PM), so moonrise at 5:52 PM means the wait after sunset is relatively short. In contrast, families in Toronto face a longer evening wait.
Why moonrise matters so much
Unlike most fasts where you break at sunset, Karva Chauth specifically requires sighting the moon. No moon sighting, no breaking the fast. This makes it the one fast where cloud cover is genuinely stressful. In cities like London or Toronto where late October skies can be overcast for days, families sometimes use a live moon tracker app alongside the traditional sieve (chalni) through which the moon is viewed.
If the sky is completely overcast, most traditions accept that waiting until the calculated moonrise time has passed is sufficient. You don’t need to physically see the moon through clouds, though families who can see it prefer the traditional sighting.
Fasting window
The nirjala (waterless) fast traditionally runs from sunrise to moonrise. That makes the length of the fast highly dependent on where you live. In Delhi, sunrise on October 29 is around 6:20 AM and moonrise around 8:20 PM, giving roughly a 14-hour fast. In London, sunrise is around 6:50 AM and moonrise around 5:52 PM, making it closer to 11 hours. New York falls in between at roughly 13 hours.
The sargi (pre-dawn meal) eaten before sunrise is a critical part of the preparation. Your mother-in-law traditionally prepares it, and it includes fruits, sweets, and something substantial enough to sustain you through the day. For families abroad where the mother-in-law may not be nearby, preparing your own sargi is perfectly fine.
Confirm your local sunrise and expected moonrise window a day or two ahead so the fast’s timing is clear in advance.
Confirm for your exact city
Use the panchang page with your city selected to confirm the tithi and general timing; for the precise moonrise minute, cross-check with a local astronomical source or app close to the date.
The modern Karva Chauth abroad
For many women in the US, UK, and Canada, Karva Chauth has become as much a social event as a religious one. Groups of friends gather in the evening dressed in their wedding finery, share mehndi, and break the fast together once the moon rises. If you’re observing alone without family nearby, a video call home at moonrise keeps the tradition alive across the distance. The sieve, the diya, and the moment of seeing the moon through the chalni before looking at your partner: these translate perfectly across time zones, even on a phone screen.
