Questions

From the Nirṇaya-sindhu, p. 47, and the Vratarāja, ff. 82⁠–⁠86.

When is Sakat Chauth?

In Delhi: Monday, 25 January 2027 (moonrise 21:12), Saturday, 15 January 2028 (moonrise 21:31) and Wednesday, 3 January 2029 (moonrise 20:34). Each city keeps its own day by its own moonrise. Nirṇaya-sindhu p. 47

Is Sakat Chauth a Sankashti Chaturthi?

Yes. It is the Saṅkaṣṭī Caturthī of Māgha, kept by the same rule, the dark Caturthī current at moonrise. The Vratarāja gives it a vow of its own, the Saṅkaṣṭa-hara Gaṇapati vow. Vratarāja ff. 82⁠–⁠86

Why are sesame laddus offered?

The Vratarāja’s vow for this day gives the naivedya as modakas fried in ghee, with sesame laddus. The texts read do not give a reason. Vratarāja ff. 82⁠–⁠86

Why is the date different in the US or UK?

The Moon rises at a different moment at each place, and each city’s clock is its own. The Caturthī is one span everywhere, so a city where it is not current at that evening’s moonrise can keep another day. Nirṇaya-sindhu p. 47

How the day is found

Read the methodology
The day
The dark Caturthī of Māgha (pūrṇimānta; amānta Pauṣa), current at moonrise. When it is current at both moonrises, the earlier day, joined with the Tṛtīyā, is kept, and at neither, the later day. Nirṇaya-sindhu p. 47, as for every Saṅkaṣṭī.
Moonrise
The Moon’s upper limb at the horizon, with refraction, rounded to the nearest minute: our convention, as on the Sankashti pages.
The vow
The Saṅkaṣṭa-hara Gaṇapati vow with its twenty-one names and its naivedya. Vratarāja ff. 82⁠–⁠86.
