The temple follows Pancharatra Agama and thenkalai tradition. The temple priests perform the pooja (rituals) during festivals and on a daily basis. Like other Vishnu temples of Tamil Nadu, the priests belong to the Vaishnavite community, a Brahmin sub-caste. The temple rituals are performed six times a day; Tiruvanandal at 8:00 a.m., Kala santhi at 9:00 a.m., Uchikalam at 12:30 p.m., Niyyanusandhanam at 6:00 p.m., Irandamkalam at 7:30 p.m. and Ardha Jamam at 9:00 p.m. Each ritual comprises three steps: alangaram (decoration), neivethanam (food offering) and deepa aradanai (waving of lamps) for both Parimala Ranganathar and Thayar.
The food offerings during the six times are curd rice, Ven pongal, spiced rice, dosa, Ven pongal and sugar pongal respectively. The worship is held amidst music with nagaswaram (pipe instrument) and tavil (percussion instrument), religious instructions in the Vedas (sacred text) read by priests and prostration by worshippers in front of the temple mast. There are weekly, fortnightly and monthly rituals.
The major festival celebrated in the temple is the Chitrai festival, celebrated during the Tamil month of Chittirai. The other festivals in the temple include the 10-day Aaandal Aadi festival celebrated during July–August, Thayar Navaratri Utsavam during the Tamil month of Purattasi (September - October), 10-day Aipasi Thula Mahostavam during Aipasi (October - November), 10-day Vaikunta Ekadasi during Margazhi (December - January), Makara Sankranthi during January and Panguni Brahmotsavam during the month of Panguni (March - April).[9]
