Chhath Puja in Calgary

Date and timing in this city

Chhath Puja falls on Kartik Shukla Shashthi, the sixth tithi of the bright fortnight of Kartik. The observance is dedicated to Surya and to Chhathi Maiya, and its central act is sun worship at rivers.

For Calgary (कैलगरी), Canada, in the America/Edmonton time zone, the date computed for Calgary's own sunrise is:

• 2026: Saturday 14 November 2026
• 2027: Wednesday 3 November 2027

These are the dates for Calgary itself, not a date carried over from an Indian calendar. The tithi is the same tithi everywhere; what changes is when it is current in local time, and that is what fixes the day of observance at your location.

Why the date can differ from India

Chhath Puja is tied to a tithi, and a tithi is a segment of the Moon–Sun relationship measured in time, not a fixed clock hour. Calgary sits many hours behind Indian Standard Time. By the time Shashthi begins or ends in India, the clock in Calgary may still be on the previous or the following day. When the tithi's window is judged against Calgary's sunrise, the observance can land on a different Gregorian date than the one used in Bihar, Jharkhand, eastern Uttar Pradesh or Nepal.

This is why families in the diaspora sometimes find that relatives in India are observing on one day while they observe on another. Neither is a mistake. Each is the correct local reckoning for that place. Where traditions differ — North and South, Smarta and Vaishnava, amanta and purnimanta reckonings — the month naming and the day count can vary as well; the brief above gives the Kartik Shukla Shashthi reckoning, which is the common one for this festival.

For personal chart questions, consult a qualified jyotishi rather than relying on a general calendar.

Where and how the community celebrates

The heart of Chhath is standing before the sun at a river: an evening offering as it sets, and a morning offering as it rises. In Calgary, the community keeps this form as far as the local setting allows. The essentials that travel are the same — a clean stretch of water or a prepared water body, the family together, the offerings, and the two sandhyas.

In the regions named in the brief, the festival belongs to Bihar, Jharkhand, eastern Uttar Pradesh and Nepal, and diaspora families carry those household customs with them. Details of the vrat, the prasad and the order of the rituals are family and regional matters, and they are best learned from one's own elders.

Practical tips

• Fix your date by Calgary's sunrise for the year, as listed above, not by an Indian panchang's Gregorian date.
• Confirm the exact tithi window for your year with a qualified jyotishi or a panchang computed for America/Edmonton.
• November in Calgary is cold; plan warm clothing and a sheltered spot for the evening and morning offerings.
• Arrange water access and any permissions well in advance, and keep the site clean afterwards.
• If you cannot reach a river, families commonly prepare a clean water body at home; follow your household tradition.
