This is the time during which the difference of the increment of longitude of the Sun and the Moon amounts to 12. Each Tithi or Lunar day is equal to 0.9483 of a day so that a lunar month, when the Moon completes a 360 degree rotation is equal to about 29.53 days.
Thithi can be found from any horoscope if we know the positions of Sun and Moon in the natal chart.
The 15 days, commencing from Amavasya (the last day of the dark half of a lunar month) to Purnima (Full moon), are called the Tithis of the Shukla-Paksha (brighter phase) and the days commencing from Purnima to Amavasya are called Krishna Paksha (darker 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.
