Tithi
As per the Indian Hindu almanac, Tithi (also spelled Thithi) is the lunar date, or the time it takes for the longitudinal angle between the moon and the sun to increase by 12°. Tithis commence at varying times of a day and differ in duration from approximately 19 to 26 hours. Tithi is one of the most important aspects of the Indian Almanac or the Panchang and therefore many Hindu festivals and ceremonies are based on Tithi Calendar.
Tithi is also considered as the first phase or portion among the 16 phases of the Moon. The 15 days(First half of the Lunar Month), commencing from Amavasya (the last day of the dark half of a lunar month) to Pournami (Full moon), are called the Tithis of the Shukla-Paksha (Waxing phase/ First phase) and the days commencing from Pournami (Full Moon day) to Amavasya (New Moon day) are called Krishna Paksha (the Waning phase/ Second phase).
In Indian Astrology, the calculation of the Tithis starts from Pratipada (The first day in each half of the lunar month) of the Shukla-Paksha.
There are 30 Tithis in each lunar month, are named as follows:
