Krishna Janmashtami is an important utsava in the temple which celebrates the birth of Krishna, the eighth avatar of Vishnu. It occurs on the eighth day of the dark fortnight of Sravana month. An inscription dated 1233 AD records a gift of 100 cows to provide milk to the temple's deity from that year's Janmashtami onwards. The utsava idol of Andal is taken round the temple and then made to occupy an ivory throne. After completing the bathing formalities and prayers, the chapter related to Krishna's birth in Bhagavata Purana is read aloud along with few sections of the Dravida Prabandha.
