Amavasya at sunrise

How the day is chosen

The new moon that ends Bhadro (Ashwin where months end at the full moon), the last day of Pitri Paksha. The day whose afternoon (the 11th and 12th muhurtas of daytime) holds the Amavasya for at least one muhurta; if both days or neither do, the earlier day (Raghunandana’s Shraddhatattva).

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
