Almanacs Set Different Dates for Bengal’s 2026 Durga Puja
Different Bengali almanacs use different calculations to decide when Durga Puja rituals should happen.
Both systems say the 2026 festival will last six days.
However, they disagree about which day will be stretched over two calendar days.
Under some almanacs, the Nabapatrika ceremony will happen on October 17.
Under Bishuddhasiddhanta, it will happen the next morning.
The two systems also give different times for Ashtami and Sandhi Puja.
These differences matter because priests and volunteers need time to prepare food and rituals.
One puja organiser is changing almanacs to give worshippers more time to participate.
Another organiser will continue using its traditional almanac.
Two almanac systems agree that the 2026 Durga Puja will span six days, from Sashthi to Dashami.
Bishuddhasiddhanta says Sashthi will extend across two days, while Suryasiddhanta-based almanacs make Saptami the two-day tithi.
The Nabapatrika procession will take place on October 17 under Gupta Press, PM Bagchi and Benimadhab Seal, and the next morning under Bishuddhasiddhanta.
Ashtami and Sandhi Puja timings differ significantly, with Bishuddhasiddhanta allowing later ceremonies than Gupta Press.
Some organisers are changing almanacs for more manageable schedules, while others are retaining their traditional systems.
