Tithi Calendar 2026
Find today’s tithi, paksha, and the exact Amavasya & Purnima dates for any month. A free Hindu tithi calendar with tithi start and end timings (IST).
A tithi is a lunar day in the Hindu calendar — the time it takes for the Moon to gain 12° on the Sun. This calendar calculates the tithi at sunrise for each day, along with the current tithi right now and its ending time.

Amavasya & Purnima Dates
What is a Tithi?
In the Hindu lunisolar calendar, the lunar month is divided into 30 tithis. Each tithi ends the moment the angular distance between the Moon and the Sun increases by a multiple of 12°. Because the Moon’s speed varies, a tithi can be shorter or longer than a solar day — which is why a tithi can occasionally be skipped (Kshaya) or repeated on two days (Vriddhi).
Shukla & Krishna Paksha
The month has two halves. Shukla Paksha is the waxing (bright) fortnight from new moon to full moon. Krishna Paksha is the waning (dark) fortnight from full moon to the next new moon.
Purnima (Full Moon)
The 15th tithi of Shukla Paksha, when the Moon is directly opposite the Sun (180°). Many vrats, Satyanarayan puja, and festivals like Guru Purnima are observed on this day.
Amavasya (New Moon)
The 30th and final tithi, when the Moon and Sun share the same longitude. It is significant for Pitru Tarpan (ancestral rites) and observances like Mauni and Somvati Amavasya.
Ekadashi
The 11th tithi of each paksha (so twice a month). Traditionally observed as a fasting day dedicated to Lord Vishnu, considered highly auspicious for spiritual practice.
Frequently asked questions
What is the tithi today?
The “Tithi at sunrise” box at the top of this page shows today’s tithi and paksha, calculated for Indian sunrise. The “Tithi right now” box shows the tithi active at the current moment and the time it ends. Both update automatically.
How is the tithi calculated?
A tithi is defined by the difference between the Moon’s and the Sun’s ecliptic longitudes. This tool computes both positions astronomically in your browser and divides the difference by 12° to get the tithi number (1 to 30). Timings are shown in IST.
Why does a tithi sometimes not appear, or repeat on two days?
The Moon does not move at a constant speed. If a tithi begins and ends between two sunrises, it never touches a sunrise and is skipped (Tithi Kshaya). If a tithi spans two consecutive sunrises, it is counted on both days (Tithi Vriddhi). The calendar reflects this the same way a traditional panchang does.
Which location and timezone are used?
The tithi at sunrise is calculated for Indian Standard Time (IST) using a representative Indian sunrise. For most of India the tithi shown is accurate; for precise muhurat or a specific city’s sunrise, cross-check with a detailed panchang.
