Purnima at sunrise

How the day is chosen

The Purnima of Asharh, by the tithi at sunrise. If the tithi is at two sunrises, the later day, provided it lasts at least three muhurtas after that sunrise; otherwise the earlier day.

Traditional (Surya Siddhanta) panjikas, such as Gupta Press and Beni Madhab Sil, can differ in tithi times by hours, so in some years the day differs too. Their dates will appear here side by side once that school has been checked against a full printed year.

Tithi times are for Kolkata, in Indian Standard Time. Panjikas give Kolkata’s festival days for all of West Bengal. Why another panjika may differ
