What is a Tithi?
A Tithi is a lunar day in the Hindu calendar — one of 30 equal divisions of the lunar month. Unlike a solar day (24 hours), a Tithi is defined by the angular relationship between the Sun and Moon. It lasts approximately 19 to 26 hours, so a Tithi can span two Gregorian days, or two Tithis can fall on the same Gregorian day.
There are 15 Tithis in Shukla Paksha (waxing moon, new moon to full moon) and 15 in Krishna Paksha (waning moon, full moon to new moon). Each Tithi has a ruling deity, a group classification, and traditional auspicious/inauspicious qualities used in selecting muhurtham dates.
Five Tithi Groups
| Nanda (1st, 6th, 11th) | Auspicious — joy and happiness |
| Bhadra (2nd, 7th, 12th) | Prosperous — wealth and success |
| Jaya (3rd, 8th, 13th) | Victorious — courage and victory |
| Rikta (4th, 9th, 14th) | Generally inauspicious for new ventures |
| Purna (5th, 10th, 15th/Amavasya/Purnima) | Complete — mixed results |

Frequently Asked Questions
Which Tithis are auspicious for important ceremonies?
For weddings and auspicious ceremonies, the favoured Tithis are: Dwitiya (2nd), Tritiya (3rd), Panchami (5th), Saptami (7th), Dashami (10th), Ekadashi (11th), and Trayodashi (13th). The Rikta Tithis (4th, 9th, 14th) are generally avoided for muhurtham.
Does the Tithi at midnight differ from the one at sunrise?
Yes. The Tithi at sunrise on a given day is the "day's Tithi" used in Panchang. Even if the Tithi changes at 10 PM, the Tithi at dawn is what determines the day's astrological character. The calculator shows the Tithi at sunrise for the selected date.
What is Amavasya?
Amavasya is the 30th Tithi (new moon day) — the last day of Krishna Paksha when the Moon and Sun are in conjunction (0° apart). It is considered especially sacred for ancestral worship (Shraddha/Tarpan) and is observed as a no-moon holy day in most Hindu traditions.
