Women everywhere keep a pūjā without the fast, the Dharmasindhu notes, and its day is the date shown. It falls on the fast day, unless the Caturdaśī lasts eighteen nāḍīs (7 h 12 min) or more after that day’s sunrise: then the pūjā moves to the next day, and the three-night fast stays where it was. DS p. 41

Unlike the other Pūrṇimā and Amāvasyā fasts, the Sāvitrī fast keeps the Caturdaśī-joined day, even with eighteen nāḍīs of Caturdaśī after sunrise, provided the tithi runs more than three muhūrtas before that day’s sunset; if it does not, the fast keeps the later day. Its three nights end on that day, and the fast is broken at the end of the tithi. NS pp. 147⁠–⁠148; DS p. 41 The texts do not say which new moon. We take the one before the Jyeṣṭha Pūrṇimā, the end of pūrṇimānta Jyeṣṭha’s dark fortnight (amānta Vaiśākha): our reading.

Questions

From the Nirṇaya-sindhu and the Dharmasindhu, with the page for each.

When is Vat Savitri?

In Delhi, 2027: the Amāvasyā form on Friday, 4 June and the Pūrṇimā form on Friday, 18 June; 2028: the Amāvasyā form on Wednesday, 24 May and the Pūrṇimā form on Tuesday, 6 June; 2029: the Amāvasyā form on Monday, 11 June and the Pūrṇimā form on Monday, 25 June. These are the pūjā days; where the three-night fast ends a day earlier, each year’s page shows it. The Amāvasyā form’s new moon, the one before the Jyeṣṭha Pūrṇimā, is our reading. NS pp. 147⁠–⁠148; DS p. 41

Why are there two dates, Amavasya and Purnima?

The Nirṇaya-sindhu records both: the southerners keep the vow on the Jyeṣṭha Pūrṇimā, and the westerners on the new moon, quoting the Bhaviṣya, with the worship at the root of the banyan. The Dharmasindhu gives the Pūrṇimā. Which new moon the Bhaviṣya means is not said; we take the one before the Jyeṣṭha Pūrṇimā. NS pp. 146⁠–⁠147; DS p. 41

When is the fast broken?

At the end of the tithi, the Pūrṇimā or the Amāvasyā. Each form’s time is in the table, for your city. NS p. 148

Why is the date different in the US or UK?

The tithi begins and ends at the same moment everywhere, but sunrise and sunset come at different hours. The test of three muhūrtas before sunset can then pick a different day in another city, and so can the eighteen nāḍīs after sunrise that move the pūjā. DS p. 41

How the day is found

Read the methodology
The date
The pūjā women everywhere keep: the fast day, or the next day when the Caturdaśī lasts eighteen nāḍīs or more after the fast day’s sunrise (DS p. 41; for the Amāvasyā form, NS p. 148: our reading).
The fast
The fast keeps the Caturdaśī-joined day when the Pūrṇimā (or Amāvasyā) runs more than three muhūrtas before its sunset, and otherwise the later day (NS pp. 147⁠–⁠148; DS p. 41).
The nights
The fast day and the two before it (NS p. 148).
Pāraṇa
After the tithi ends (NS p. 148).
The new moon
The one before the Jyeṣṭha Pūrṇimā (pūrṇimānta Jyeṣṭha): our reading, since the texts do not say.
Sunrise and sunset
At the centre of the Sun’s disc, with refraction, for the chosen city. Every date is that city’s own.
