 The Munneswaram temple is well known for its celebration of Navaratri and Sivarathri functions. Navaratri lasts for nine days and is dedicated to various aspects of the presiding goddess, whereas Sivarathri is dedicated to Siva. Both these functions primarily attract Hindus to the temple. The annual Munneswaram festival is an important part of the temple calendar and it attracts Hindus, Buddhists, Catholics and even Muslims. Until the 1830s the festival lasted up to 18 days but since the 1960s it lasts for 28 days in the months of August and September. The festival begins with the hoisting of the temple flag. This is followed by 13 days of internal temple processions conducted in the outer pathways of the Siva temple. On each day of the festival, the images of Ganesha, Skanda, and the presiding consort goddess are paraded around the temple. Local Pattuva village deity temples also have festivals that coincide with the annual festival. Villagers belonging to Maradankulama and Uddappu sponsor a day each of the 28-day festival.
