Bhai Dūj
The popular claimYama Dvitīyā is an afternoon, and in 2026 the afternoon is Wednesday.
Bhai Dūj closes the sequence that Dhanteras opened, and like Dhanteras it is fixed to a part of the day rather than to a date.
The rule
The tithi is Kārttika śukla Dvitīyā, the second of the bright half. The nibandhas call the day Yama Dvitīyā and take it on the day Dvitīyā is present in the aparāhna — the fourth of the five equal parts of daylight, a window of a little over two hours starting a bit after one in the afternoon.
There is one further clause, and it runs the opposite way from Dussehra's. Where Dvitīyā reaches the aparāhna on both of two consecutive days, the second is taken. The Dharmasindhu states it for this tithi specifically.
2026, computed
Dvitīyā begins at 2:00 PM on Tuesday 10 November and ends at 3:53 PM on Wednesday 11 November — Delhi times from this site's engine.
- Tuesday 10. Sunrise 6:40 AM, sunset 5:29 PM — ten hours forty-nine minutes of light, each fifth 130 minutes, aparāhna roughly 1:10 to 3:20 PM. Dvitīyā arrives at 2:00, so it is present for the later part of the window only.
- Wednesday 11. Sunrise 6:41, sunset 5:28; aparāhna roughly 1:11 to 3:19 PM. Dvitīyā, which ends at 3:53, covers the whole of it.
Both afternoons see some Dvitīyā, so the two-day clause applies and the second day is taken — and the second day is also the one with full coverage. Bhai Dūj 2026: Wednesday 11 November.
Toronto: Dvitīyā runs from 3:30 AM on the 10th to 5:23 AM on the 11th, local time. Tuesday's aparāhna in Toronto — 12:59 to 2:57 PM, from a 7:06 sunrise and a 4:55 sunset — is covered; Wednesday's is not, because the tithi ended before dawn. Toronto keeps Bhai Dūj on Tuesday 10 November. Delhi on Wednesday. Both correct.
What the day carries
The name in the texts is Yama's. The Skanda Purāṇa tells of Yama visiting his sister Yamunā on this tithi; she feeds him, and he grants that whoever is fed by a sister on this day is under his protection. The tilaka and the meal are the whole rite, and they are why the day is fixed to an afternoon — it is the hour of the meal.
The bathing in the Yamunā that some traditions keep on this day comes from the same story. So does the Bengali Bhāi Phõṭā and the Marathi Bhāu Bīj; one tithi, several names.
Notice what the rite is not. It is not a vrata — nobody fasts. It has no pūjā of a deity at its centre; the brother is the guest and the sister is the host. It is the only one of the five days whose whole content is a relationship between two living people, and the texts treat it that way: the description in the Dharmasindhu is a few lines, most of them about the meal.
The five days, seen whole
Dhanteras, Naraka Caturdaśī, Lakṣmī Pūjā, Govardhan, Bhai Dūj: five tithis, the thirteenth of one fortnight to the second of the next, running across the new moon. Each is fixed to a different part of its day — pradoṣa, pre-dawn, pradoṣa and niśītha, forenoon, aparāhna — which is why they do not simply fall on five consecutive dates. In 2026 in Delhi they land on Friday, Sunday, Sunday, Tuesday and Wednesday: a shared day and an empty one. That is not a calendar being careless. It is five rules being applied.
Why the times above are not the times for you
Aparāhna is measured from your sunrise and sunset. In November, Toronto's daylight is about an hour shorter than Delhi's and its afternoon window sits earlier in the clock; combined with the ten-and-a-half-hour offset, that is enough to put the two cities on different days this year. This site's panchang computes the window for the city you type.
What this page does not say
It does not say what the tilaka protects against, and it does not turn Yama's promise into a warning for the sister who is elsewhere that day. The rite is a meal between a brother and a sister at a named hour. The texts describe it; this page describes the texts.
