    About this calendar

    Moon dates, simply explained

    What is a moon date (tithi)?

    A tithi is one lunar day: the time the Moon takes to move 12 degrees ahead of the Sun. A lunar month has 30 tithis, 15 in the bright half (Shukla paksha) and 15 in the dark half (Krishna paksha).

    Why does a moon date not start at midnight?

    The English calendar day always runs from midnight to midnight. A moon date starts and ends whenever the Moon reaches the next 12-degree step, so it can begin in the afternoon and end the next evening. Its length varies from about 19 to 26 hours.

    Which moon date counts for a fast or festival?

    Most traditions use the tithi that is running at sunrise (udaya tithi). That is why this page also shows the tithi at sunrise for your city.

    What is the difference between Purnimanta and Amanta?

    Both use the same tithis. In Purnimanta (Rajasthan and most of North India) a month ends on Purnima, the full moon. In Amanta (Gujarat, Maharashtra and the South) a month ends on Amavasya, the new moon. So during Krishna paksha the month name differs by one.

    How accurate are these times?

    The times come from astronomical calculation of the Sun and Moon. We compared them with an established panchang for several dates in 2026 and 2027, and they agreed within one minute. Nakshatras use the Lahiri (Chitrapaksha) ayanamsa, the standard used by the Government of India.
