Aadi Perukku is a festival of fertility & prosperity celebrated in south India for over 500 years. It was mentioned in Sangam Tamil literature, Paripadal, written in the 14th century about the celebration of this festival.
Chitrannam is a platter of different rice varieties usually prepared on the day of Aadi perukku ie. 18th day of Aadi month in Tamil calendar. It is believed that whatever we do on that day would grow manifold, so farmers used to sow their seeds expecting a good yield, businessmen venture into new business, and people in every walk of life eager to start something new.
