Tithi Calendar 2026
A Tithi is a lunar day in the Hindu calendar — the time it takes the Moon to move 12° ahead of the Sun. Each lunar month has 30 tithis, split across two Pakshas (fortnights).
The Two Pakshas
Shukla Paksha
The waxing fortnight, from Amavasya to the full Moon (Purnima), when the Moon grows brighter each night.
Krishna Paksha
The waning fortnight, from Purnima to Amavasya, when the Moon's visible portion shrinks each night.
Key Tithis to Know
Ekadashi
The 11th tithi of each Paksha — considered highly auspicious for fasting and worship; occurs twice a month.
Purnima
The full Moon day, marking the end of Shukla Paksha — significant for many festivals and observances.
Amavasya
The new Moon day, marking the end of Krishna Paksha — associated with ancestor worship and certain rituals.
Chaturthi
The 4th tithi of each Paksha, notably observed as Sankashti/Vinayaka Chaturthi in honour of Lord Ganesha.
Ashtami
The 8th tithi of each Paksha, observed for various regional and goddess-related festivals.
Navami
The 9th tithi of each Paksha, closely tied to Durga Puja observances in Assam.
