Where it began
Chithra Pournami means the full moon of Chithirai, the first month of the Tamil year. On this night the moon is in the Chitra star, which gives the day its name.
Legend says Chitragupta was born on this day and serves Yama, writing down the deeds of every person. Devotees pray to him for forgiveness and a good life, and give food and help to others.
One story tells that Indra worshipped Shiva at Madurai on this full moon to be freed from his wrongs, which is why the day is linked to washing away mistakes.
