A lunar calendar comprises of 30 Tithis or Dates. A Tithi exemplifies a Lunar Day according to the Hindu Calendar. A Tithi is evaluated when the Moon proceeds 12 degrees east from the Sun and this is envisaged as the first Tithi also known as Pratipada Tithi during Shukla Paksha. On the contrary, when the Moon locomotes by 180 degrees then it is said to be Purnima or full Moon and at last when the Moon transposes by 360 degrees it is known as Amavasya. As the speed of Sun and the Moon are mercurial in nature, thus the length of Tithi alters to an extent that it can range from 26 hours to 21 hours and 34 minutes.
