Timings on Wednesday, 23 December 2026
- Pradosh Kaal to 2 h 36 min · 23/12/2026 (Wed)
Rule applied: Smarta — The tithi covers the required time on this day only.
How the date is determined
- The date is Margashirsha Shukla Paksha Purnima; the month name is the same in the Amanta and Purnimanta systems.
- It falls on the day when this tithi prevails during Pradosh Kaal — the first fifth of the night after sunset.
- If the tithi prevails at that time on two consecutive days, the day on which it covers more of that period is taken.
- If the tithi does not touch that period on any day (a kshaya tithi), the Hindu day on which the tithi prevails longest is used.
- In a year with an Adhik month of the same name, it is observed in the regular (Nija) month.
Traditional variation
Kept mainly in Maharashtra, Karnataka, Goa, Gujarat, Andhra Pradesh and Telangana. Some panchangs take the day on which Purnima prevails at sunrise (udaya tithi); when Purnima covers the evening of one day and the sunrise of the next, they give the next day.
This is the date given by the rule shown above for the selected place. It is not the only valid date: regional Panchangs, family customs and sampradayas may observe it on a different day.
Rule source: Datta sampradaya tradition (no Nirnaya Sindhu or Dharma Sindhu ruling of its own): Dattatreya appeared at dusk on Margashirsha Purnima, so the day on which Purnima prevails at Pradosh; on two evenings the evening with the greater coverage
