Every act, from the leaf entry to the immersion, is held on the tithi current at sunrise, even for a muhūrta, which is how the Tithi-tattva reads its ghaṭikā. The worship usually takes three days, and two or four when a tithi is lost or gained. Tithi-tattva pp. 87⁠–⁠89 Each year’s page gives every act with its time and page, and the Nirṇaya-sindhu’s and the Dharmasindhu’s days where they differ.

Questions

From Raghunandana’s Tithi-tattva, with the Nirṇaya-sindhu and the Dharmasindhu where they differ.

When is Durga Puja?

By Raghunandana’s Tithi-tattva, with the days reckoned at Kolkata for every city: 18 to 21 October 2026, with the Mahāṣṭamī on Mon 19 Oct; 6 to 10 October 2027, with the Mahāṣṭamī on Thu 7 Oct; 25 to 28 September 2028, with the Mahāṣṭamī on Tue 26 Sep; 13 to 16 October 2029, with the Mahāṣṭamī on Sun 14 Oct. Tithi-tattva pp. 87⁠–⁠89

Why can Maha Navami differ between calendars?

The Tithi-tattva keeps the Mahānavamī on the day after the sandhi, on the Navamī current at sunrise. The Nirṇaya-sindhu and the Dharmasindhu take the Navamī of the Aṣṭamī day when it covers three muhūrtas before that day’s sunset, and otherwise the next day, so in many years they keep it a day earlier. Tithi-tattva p. 88; Nirṇaya-sindhu pp. 272⁠–⁠273; Dharmasindhu p. 69

Is Durga Puja the same as Navratri?

It falls in the same bright fortnight of Āśvina as Navratri, on its sixth to tenth days. Bengal’s schedule follows Raghunandana’s Tithi-tattva, and the Navratri pages follow the Nirṇaya-sindhu and the Dharmasindhu, so a day can differ, the Mahānavamī most often.

Is the date different in the US or UK?

No. The days are reckoned at Kolkata, where this Bengal rule is kept, for every city, and the times are in your local clock. Where a city’s own sunrise would give another day for an act, the schedule says so. Tithi-tattva pp. 87⁠–⁠89

How the days are found

Read the methodology

The rule: Every act on the tithi current at sunrise for at least a muhūrta (Tithi-tattva pp. 87⁠–⁠89); a tithi holding no sunrise gives the day it falls on (our reading of p. 89).
Bodhana: The Ṣaṣṭhī’s evening twilight, three ghaṭīs after sunset (our reading), with the two-day rules of p. 75; the āmantraṇa on the evening before the leaf entry (p. 76).
Forenoon: The leaf entry and the immersion in the forenoon, sunrise to midday (our reading), never at night (pp. 76⁠–⁠77, 86⁠–⁠87). The movable lagna or navāṃśa the text wants (p. 89) is listed beside them.
Sandhi Puja: The last daṇḍa of the Aṣṭamī and the first of the Navamī, 48 minutes at the junction (p. 86).
Mahanavami: The day after the sandhi, on the sunrise Navamī (p. 88). The Nirṇaya-sindhu’s and the Dharmasindhu’s day is shown beside it where it differs (NS pp. 272⁠–⁠273; DS p. 69).
One set of days: Kolkata’s days for every city, where this Bengal rule is kept. Where the city’s own sunrise would give another day, the schedule notes it.
Sunrise and sunset: At Kolkata for the days, at the centre of the Sun’s disc, with refraction. The forenoon and evening windows are the chosen city’s own on those days.
