A Tithi (திதி) is a lunar day in the Hindu calendar — one 30th division of the lunar month. There are 30 Tithis in a month (15 in Shukla Paksha/waxing and 15 in Krishna Paksha/waning). Each Tithi has a ruling deity, a group classification, and auspicious/inauspicious qualities.

What are the five Tithi groups?

Tithis are classified into 5 groups: Nanda (1st, 6th, 11th) — blessed; Bhadra (2nd, 7th, 12th) — prosperous; Jaya (3rd, 8th, 13th) — victorious; Rikta (4th, 9th, 14th) — generally inauspicious; Purna (5th, 10th, 15th/Purnima/Amavasya) — full.

Does a Tithi always correspond to one Gregorian day?

No. A Tithi is a lunar unit and lasts approximately 19–26 hours. It can span two Gregorian days or, rarely, two Tithis can fall on the same Gregorian day. The Tithi at sunrise on a given day is considered the Tithi for that day.

What is a Tithi?

A Tithi (திதி) is a lunar day — one of 30 equal divisions of the lunar month in the Hindu calendar. Unlike a solar day (24 hours), a Tithi is defined by the angular relationship between the Sun and Moon, and lasts approximately 19 to 26 hours.

There are 15 Tithis in the waxing phase (Shukla Paksha, from new moon to full moon) and 15 in the waning phase (Krishna Paksha, from full moon to new moon). Each Tithi has a ruling deity, a Tithi group, and traditional auspicious or inauspicious qualities used in selecting muhurtham dates.
