An 8 day festival starting with flag hoisting and ending with 'Arattu' ()on Thiruvonam day is held annually in the month of 'Medam' (April-May).

In December every year, Maha Ganapathihomam and Bhagavatha Sapthaham are conducted. There is Prasadam Oottu on all days, Devotees in large numbers turn up on all the seven days and take part in Prasada Oottu.

During Navarathri, in the month of 'Kanni' (September-October) Devee Bhagavatha Navaham and Navarathri Sangeetholsav are conducted in the Navaratri Mandapam in Bhagawathi Temple. On Vijaya Dasami day, Saraswathi Pooja and Vidyarambham are also conducted. Hundreds of children are initiated into the world of letters by eminent men of letters on that day.

Amavasi (New moon) day in the month of Karkatakam (July-August) is a special festival day for the temple. On this day Hindus offer 'Pithrubali' () in holy places, in worship of their dead ancestors. Unlike in other temples, there is no provision here for the traditional 'Vavu bali' (). Instead, 'Namaskaram' () offering is made. Tens of thousands of devotees, even when from far away, throng the temple on the day, to make Namaskaram offering. 'Padachoru' () along with the dish 'Thalkkari' () is given as Prasadam for Namaskaram. 'Pada choru' () is prepared from the best quality 'Puncha raw rice'. More than 20 quintalls of this rice is used to prepare Padachoru on Karkataka Vavu day. 'Thalkkari'() is given free of cost along with 'Padachoru' (). This dish is prepared from the stalk of Kattuchembu (Wild cococasia). Kattuchembu stalk normally produces unbearable itching. But strange as it may seen, the dish prepared from it produces no itching. Not only that, the dish is delicious, nutritive and medicinal. About 20 quintalls of the stalk have to be collected from far off places, cleaned and sliced. The reputation of the Thalkari is so high that people form neighboring districts also have started to come over here to collect it.

Amavasi of months Thulam (October-November) and Kumbam (February-March) are also observed though with lesser pomp. Thalkkari is available on these days also.

Lord Dhanwanthari being an incarnation of Lord Vishnu, 'Janmastami' () in the month of Chingam (August-September) when star Rohini and Astami thithi come on the same day, is celebrated with great rejoice as the birthday of Lord Krishna. 'Unni Appam Nivedyam' () is a special vazhipadu on the occasion.

It is believed that Lord Dhanwanthari revealed himself to the world on Thrayodasi Thithi of Black fortnight in Karthika month of Saka Varsha (October-November), during the churning of the sea of milk (Paalazhi) by Devas and Demons. Hence that day is celebrated as Dhanwanthari Jayanthi.

On all Thiruonam days (once in a month) there is a special pooja. Devotees in large numbers register their names for the pooja. They are given Prasada oottu along with Palpayasam. The pooja offered by couples who even after several years of their marriage are childless. They fast and attend the noon pooja. There after they are given prasadam oottu along with palpayasam and butter nivedyam. It is an unshakable belief of the devotees that twelve consecutive Thiruonam poojas will definitely bear fruit. Many couples who have realized their prayers, come to the temple with their off springs to offer their worship. Some even perform Santhanagopalam Kathakali Vazhipadu. (See special Vazhipadus)
