Every day, Vila puja (Morning/special puja), Shanti puja, Uchchikaalam puja (noon puja), Sayaraksha puja, and Arthajamam puja (mid-night puja) are performed.

The Vaikasi Brahmotsavam festival is celebrated for 10 days at the Kannathal temple. Apart from this, the Kolattam festival is celebrated in Aippasi, the Thailakappu Utsavam in the month of Thai, the Mulakottu festival in the month of Aadi, the Navaratri festival, the Sevvai Festival and the Kaliyatta festival which occurs once in 12 years are also celebrated.

People with visual impairment are said to be cured if they fast for 48 days, worship the goddess every day, and apply the goddess' holy water to their eyes. Nine silver pots and one gold pot are used to grow the seeds during the Mulai Kottu festival. Childless couples pray to the goddess by vowing to offer a sugarcane cradle. Upon being blessed with a child, they fulfill their vow in gratitude.

The main sanctum, ardhamandapam and mahamandapam are found in the front of the temple. The temple premises has a tall Rajagopuram with intricate carvings, an Alankara mandapam and a Karnakaal mandapam. There is also a beautiful theppakulam (temple tank) opposite the temple.

The goddess Kannudaiya Nayaki, also known as Kannathal, is considered by many to be a powerful deity who grants the gift of sight to the blind and the visually impaired. In this temple, the goddess is enshrined as a self manifested idol (swayambu murti). In the sanctum of this temple, goddess Kannathal is depicted with her head slightly tilted, trampling a demon under her feet, which is adorned with anklet, and with her other leg folded and raised. In her eight hands, the goddess holds a kapala (skull), agni (fire), sulam (spear), a udukkai (small drum), a short sword, a parrot, a shield, and a bell.

The renovation of the Kannudaya Nayaki Amman temple, such as the placement of the flagstaff (dwajasthambam), were made by Sethupathi kings, as can be seen from the song "Kanaka Visaya Raghunatha Sethupathi siddha Kodi Kamba Mandapam Pugazha Koovai Kuyile" in the book "Kannudaya Ammai Pallu" sung by Muthu Nayakam poet. It is reported that the processional deity-Kaliyattkannudaya Nayaki- is listed as Chamundeeswari in the Sivagangai Devasthanam register. The Amman, adorned as the Kaliyattkannudaya Nayaki with eight arms, is taken on a procession on a silver chariot in a seated form. Every year, before the Kannudaya Nayaki Amman Velliratham (silver chariot) festival begins in the tamil month of Panguni, a ceremony called "Sēngai Vettu" takes place, where people voluntarily involve themselves in the dredging process of the temple's Thirukkulam (temple tank)- a tradition that continues to this day. On the day of the Thirukarthigai festival, the goddess appears on the Anna Vahanam (swan vehicle), and on the same day, the ceremonial burning of the Chokkappanai takes place.
