A tithi is the time it takes for the longitudinal angle between the Moon and the Sun to increase by 12°.Tithis begin at various times of the day, and vary in duration.

A pakhṣa (as in suklapaksh or krishanapaksh) is a lunar fortnight and consists of 15 tithis.

A māsa, or lunar month (about 29.5 days), is divided into two paksh. A ritu (season) is two māsas.

An ayana is three ritus.

A year is two ayanas
