Hindu Festival Calendar 2027

Hindu festivals follow the lunar tithi, not the solar date. A tithi is each 12° the Moon gains on the Sun, so it lasts 19 to 27 hours and can change in the middle of a day. That is why each festival has a rule for the part of the day its tithi must touch — nishita (midnight) for Janmashtami, pradosh (early night) for Diwali, madhyahna (midday) for Ram Navami.

For each year our engine finds the lunar months (amanta, adhik months included), the start and end of every tithi, and these parts of the day from New Delhi’s sunrise and sunset, then applies each festival’s rule. Holika Dahan and Raksha Bandhan also avoid Bhadra; Ekadashi keeps Dwadashi for the parana. Makar Sankranti follows the Sun’s entry into sidereal Capricorn.

We checked our 2025 and 2026 dates against a published New Delhi almanac. Where traditions differ — Vaishnava Ekadashi, South Indian Hanuman Jayanti, amanta and purnimanta month names — each page says so.
