Hindu Festival Calendar

Every date is computed live from the actual positions of the Sun and Moon using the Swiss Ephemeris (the Drik or siddhantic method), with the Lahiri ayanamsa — the same engine that powers our panchang. No precomputed Vakya tables or approximations are used.

A festival is observed on the day its governing tithi actually prevails at the relevant time of day, computed for a reference location. Many sites round to a default city or use an approximated sunrise table, so the observed day can shift by a day when the tithi begins or ends near sunrise.

The major annual festivals (Diwali, Holi, Navratri, Ganesh Chaturthi, and more), the solar Sankrantis, and the recurring tithi observances such as Ekadashi, Pradosh, Purnima, and Amavasya — with cited significance for each.
