What Tithi Means
The tithi is one of the five elements (angas) of the Hindu Panchang — alongside vara (weekday), nakshatra, yoga, and karana. It's the most important for ritual timing. Festivals, fasts, religious ceremonies, and many cultural observances are scheduled by tithi rather than by Gregorian date. Diwali falls on Amavasya, Karwa Chauth on Krishna Paksha Chaturthi, Janmashtami on Krishna Paksha Ashtami — all are tithi-based.
The Two Pakshas
A lunar month is divided into two halves: Shukla Paksha (the bright/waxing fortnight, from new moon to full moon) and Krishna Paksha (the dark/waning fortnight, from full moon to new moon). Each half has 15 tithis. Shukla Paksha is generally considered favorable for beginning new projects, while Krishna Paksha favors completion, surrender, and contemplative practices.

Frequently Asked Questions
What is a Tithi?+
A Tithi is a lunar day in the Hindu calendar — the time it takes for the Moon to gain 12° on the Sun. There are 30 tithis in a lunar month, divided into two halves: 15 in Shukla Paksha (waxing fortnight, from new moon to full moon) and 15 in Krishna Paksha (waning fortnight, from full moon to new moon). Tithis don't have fixed clock times — they begin and end based on Sun-Moon angular distance.
What are the 30 Tithis?+
Pratipada, Dwitiya, Tritiya, Chaturthi, Panchami, Shashti, Saptami, Ashtami, Navami, Dashami, Ekadashi, Dwadashi, Trayodashi, Chaturdashi, then either Purnima (full moon, Shukla Paksha) or Amavasya (new moon, Krishna Paksha) depending on the half. Each name simply means the ordinal number — 'Panchami' means fifth, 'Saptami' means seventh, and so on.
Why does my Tithi differ from the calendar?+
Tithis are calculated based on the angular distance between the Sun and Moon, which doesn't align with civil days. A tithi can begin in the middle of one civil day and end during the next. Most Panchangs report the tithi 'prevailing at sunrise' as the day's tithi. This calculator computes the tithi at noon for the given date and location.
Why are some tithis considered auspicious?+
Each tithi has traditional associations: Pratipada is good for new ventures, Panchami for educational matters, Ekadashi for fasting and spiritual practice, Purnima for completion ceremonies. Some tithis like Chaturthi (especially in Krishna Paksha), Ashtami, and Chaturdashi are considered less favorable for important undertakings. The full Panchang considers tithi alongside vara, nakshatra, yoga, and karana.
