A Tithi (तिथि) is a lunar day in the Hindu Panchang, defined as the time it takes for the longitudinal angle between the Moon and the Sun to increase by 12°. Unlike solar days which are fixed at ~24 hours, tithis vary in duration from approximately 19 to 26 hours and can begin at any time of day or night.
There are 30 tithis in a complete lunar month (one full cycle from New Moon to New Moon): 15 in Shukla Paksha (waxing, bright fortnight) and 15 in Krishna Paksha (waning, dark fortnight). Each tithi is presided over by a specific deity and has particular characteristics that make it auspicious or inauspicious for different activities.
In Panchang calculations, the tithi at the time of sunrise determines the "tithi of the day." If a tithi begins after sunrise and ends before the next sunrise, it is called a "Kshaya Tithi" (lost tithi). If the same tithi spans two sunrises, it is called an "Adhika Tithi" (extra tithi). These variations affect festival dates and muhurat calculations.
Shukla Paksha (bright half): Pratipada → Dwitiya → Tritiya → Chaturthi → Panchami → Shashthi → Saptami → Ashtami → Navami → Dashami → Ekadashi → Dwadashi → Trayodashi → Chaturdashi → Purnima
Krishna Paksha (dark half): Pratipada → Dwitiya → ... → Chaturdashi → Amavasya

Hindu festivals and vrats are determined by tithi (not solar date), which is why they fall on different Gregorian dates each year. Key tithi-festival mappings:
Today's tithi is shown at the top of this page with the exact end time, calculated for your selected city based on the Moon-Sun angular distance.
Shukla Pratipada, Dwitiya, Tritiya, Panchami, Saptami, Dashami, Dwadashi, and Trayodashi are generally auspicious. Chaturthi, Ashtami, Navami, and Chaturdashi are typically avoided for new ventures.
Shukla Paksha is the waxing (bright) fortnight from New Moon to Full Moon. Krishna Paksha is the waning (dark) fortnight from Full Moon to New Moon. Shukla Paksha tithis are generally preferred for auspicious activities.
Tithi is determined by the Moon-Sun angular distance, which is the same everywhere. However, the "tithi of the day" depends on which tithi is active at local sunrise, which varies by longitude and timezone.
