Rule: the day the tithi is current at local sunrise (udaya tithi).

What the day observes

The worship of the Sun on the sixth day of the bright fortnight of Kartika, the great festival of the Terai, Bihar and eastern Uttar Pradesh. Four days: Nahay Khay, the bath and the first meal; Kharna, the day-long fast broken at dusk; the evening offering (sandhya arghya) to the setting Sun on Shashthi, standing in the water; and the morning offering to the rising Sun on Saptami, after a fast without water through the night.

How it is kept

The offerings at the ghat at sunset and sunrise, the thekua and fruit in the soop, and the exact discipline of the fast.

Common questions

When is Chhath (Surya Shashthi) 2027 in Sydney?

Thursday 4 November 2027. Kartika Shukla Shashthi; the tithi runs Thu, 4 Nov, 1:03 am to Fri, 5 Nov, 3:09 am Sydney time.

When is Chhath (Surya Shashthi) 2027 in Nepal?

Thursday 4 November 2027 in Kathmandu. Kartika Shukla Shashthi; the tithi runs Wed, 3 Nov, 7:48 pm to Thu, 4 Nov, 9:54 pm Nepal time.

When is Chhath (Surya Shashthi) 2027 in the United States?

Thursday 4 November 2027 in New York, Wednesday 3 November 2027 in Los Angeles. US sunrises fall ten to fifteen hours behind Kathmandu's, so when the tithi ends in that gap the US keeps the festival a day earlier than Nepal.

Why is Chhath (Surya Shashthi) on a different day in different countries?

Because the day is decided by which civil day the tithi (lunar day) is current at local sunrise. Sydney's sunrise is four to six hours ahead of Kathmandu's and New York's ten hours behind, so a tithi that ends between two sunrises gives a different day. In 2027 the cities split across Wed, 3 Nov and Thu, 4 Nov.

How is the Chhath (Surya Shashthi) date calculated?

Sun and Moon positions from Meeus' algorithms with the Lahiri ayanamsa, amanta lunar months named by the solar ingress inside them, and the day on which the tithi is current at local sunrise (udaya tithi). Tithi boundaries are accurate to a few minutes; a boundary within minutes of sunrise is worth checking against your temple's panchang.
