The temple follows Saivite tradition. The temple priests perform the pooja (rituals) during festivals and on a daily basis. The temple is open from 6am - 12 pm and 4-8:30 pm on all days except during new moon days when it is open the full day. The Ranganathaswamy temple is present in the same campus and the water for daily rituals is taken from the same tank for both the temples. During a yearly festival the festival image of Ranganathar is brought to the Nanjundeswarar temple for an event called Ambu yerithal. The Shivaratri festival during the Tamil month of Vaiakasi (May - June) and Annabishekam in Aippasi (October - November) being the most prominent. During the tenth day of Navratri festival, the festival image of Nanjundeswarar (a form of Shiva) and Ranganathaswamy temple, Karamadai (a form of Vishnu) are sported together fighting demons with bow and arrow. The union of Shiva and Vishnu in such a form is one of its kind in Tamil Nadu.
