Tithi Calendar: All 16 Tithis and Their Next Dates

15 tithis in each paksha — 14 shared names plus Purnima and Amavasya make 16 names, 30 tithis a month. A tithi is the time the Moon takes to gain 12° on the Sun, so it does not follow the clock: it lasts roughly 19 to 26 hours and can begin at any hour of the day or night.

The panchang therefore names each civil day by the tithi running at sunrise — the udaya tithi. That rule has two consequences. When a short tithi begins after one sunrise and ends before the next, no sunrise falls inside it and it drops out of the day count: a kshaya tithi. When a long tithi spans two sunrises, both days carry its name: a vriddhi tithi. That is why a month can show Navami twice or skip Dashami altogether. It is also why a vrat can fall on a different day from the date its tithi first begins: each vrat adds its own deciding hour, such as moonrise for Sankashti or dusk for Pradosh. The dates below are vrat days fixed by our panchang engine for New Delhi and matched against DrikPanchang.

The 16 tithis

The five tithi groups

Muhurta Chintamani and Narada Samhita sort the fifteen tithis of each paksha into five groups of three, repeating in order: Nanda (“joyful”) — Pratipada, Shashthi, Ekadashi; Bhadra (“good”) — Dwitiya, Saptami, Dwadashi; Jaya (“victorious”) — Tritiya, Ashtami, Trayodashi; Rikta (“empty”) — Chaturthi, Navami, Chaturdashi; and Purna (“full”) — Panchami, Dashami, Purnima and Amavasya. Muhurat texts read the group together with the vaar and nakshatra; Rikta tithis, for instance, are traditionally kept for worship and completion rather than beginnings — yet Chaturthi and Navami carry some of the most-kept vrats of the year.
