Questions

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

When is Nag Panchami?

In Delhi: Friday, 6 August 2027; Wednesday, 26 July 2028; Tuesday, 14 August 2029. Each is the Śrāvaṇa śukla Pañcamī, joined with the Ṣaṣṭhī. NS p. 164, quoting the Camatkāra-cintāmaṇi

Why the later Panchami?

For the worship of serpents, the Nirṇaya-sindhu takes the Pañcamī joined with the Ṣaṣṭhī, quoting the Camatkāra-cintāmaṇi: the serpents are pleased on it, and the earlier day is joined with the Caturthī. The Dharmasindhu limits this. The later day needs three muhūrtas of the Pañcamī after its sunrise, or two when the Caturthī before it ran more than three; with less, the earlier day is kept. NS p. 164; DS p. 44

Why is the date different in the US or UK?

The Pañcamī begins and ends at the same moment everywhere, but sunrise comes at different hours, so the muhūrtas it runs after sunrise differ from city to city. Where it runs too briefly after the later sunrise, the earlier day is kept. DS p. 44
