Avani is the month, noted for Vinayaka Chaturthi festival and the Avani-moolam festival. Vinayaka is the most popular deity in the whole of South India. Vinayaka festival is performed on the fourth day, Chaturthi thithi, on the bright fortnight of the Tamil month of Avani. Scholars say, that the month of Avani was originally the first month of a year, long before the time of Saint Tholkappiyar and Vinayakar being the god who is usually worshipped first, at the very start of every act. His festival has appropriately come to be celebrated in the first month of Avani. Avani Moolam (Scorpionis), is another important festival of this month. It is held as very sacred and is celebrated not only in Madurai temple but also in all the Siva temples of Tamilnadu.
