Karva Chauth 2027 falls on Monday, October 18 in India, on Kartik Krishna Chaturthi. Check which date your family’s local panchang or community follows, since festival dates can genuinely shift by a day for observers well outside India’s time zone.
For women observing Karva Chauth abroad, the single most important piece of information is: what time does the moon rise in my city? Everything else, the sargi, the puja, the stories, you know. But moonrise is what you’re waiting for all day. And it’s different everywhere.
Why moonrise time differs by city
Moonrise depends on your city’s longitude and latitude, not just the date. A published India-based moonrise time has no direct bearing on when the moon rises in New York, Toronto, London, or Dubai; each needs its own calculation.
Here is what is fixed and what is not. The date is fixed by the tithi, and Drik Panchang lists the same date, Monday, October 18, 2027, for all five cities below. The moonrise minute is not fixed. It is different in each city and has to be looked up for yours.
| City | Karva Chauth 2027 | Time zone |
|---|---|---|
| New Delhi | Monday, October 18 | IST |
| London | Monday, October 18 | BST |
| New York | Monday, October 18 | EDT |
| Toronto | Monday, October 18 | EDT |
| Dubai | Monday, October 18 | GST |
Calculated for each city’s own location and time zone, from the Drik Panchang snapshot for that city (fetched September 2026). The snapshot lists dates only. It has no moonrise times, so this article gives none. A moonrise time quoted for another city, or from India, does not apply to yours.
Even within one country the moonrise minute differs. Toronto and Vancouver do not see the moon at the same clock time on the same night. If you are in a Karva Chauth WhatsApp group with friends across Canada, do not assume their moonrise time applies to you.
How these dates are produced and checked is on the methodology page.
Fasting window
The nirjala (waterless) fast traditionally runs from sunrise to moonrise. Its length depends on your city’s sunrise and moonrise that day, so look both up for your city before the day.
Some practical tips that experienced Karva Chauth observers swear by: eat a proper sargi (pre-dawn meal) with slow-release energy foods like dahi, paratha, dry fruits, and banana. Avoid overly salty or spicy food in the sargi, as it’ll make the thirst worse. If you’re in a dry climate or doing a physically demanding job, the nirjala aspect is the hardest part by far.
The evening puja
The Karva Chauth katha (story) is read in the late afternoon or early evening, traditionally in a group of women sitting together. For women abroad, community groups and temple organizations often arrange a gathering. If no community event is available, the puja can be done at home with a group on video call, which has become completely normal for diaspora families.
The puja involves a karva (small clay pot) filled with water, mehndi, bangles, and the katha book. After the katha, women wait for moonrise. The fast-breaking ritual: look at the moon through a sieve (chhalni), then look at your husband’s face through the same sieve, then he offers you water and the first bite of food.
What if the sky is overcast?
This is a real problem in cities like London, Toronto, and Seattle, where October skies are frequently cloudy. If you can’t see the moon, the traditional guidance varies by family and community. Some families break the fast at the calculated moonrise time regardless of visibility. Others wait until a gap in the clouds. Having the calculated moonrise time is your backup plan for a cloudy night.
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, since it can shift by a few minutes depending on your exact location and the calculation source.
