This marks the new moon day. The moon, which is one of the Nava Grahas denoted as CHANDRAN, is considered as a deity who showers blessings of prosperity and good health. This occurs once every month, usually a fortnight after Pournami. The Amavasai, which occurs in the month of Puratasi, that is the end of September and the beginning of October, is considered of special importance and celebrated as Mahaliya Amavasai. Fasting during this day brings peace to the belated and ancestors. It is a ritual to give Annadhanam (food) to Brahmins on this day.
