Karthigai Deepam
The Karthigai Deepam festival is celebrated in the Tamil Month of Karthigai (November - December). It begins on Uttradam day with flag hoisting and goes on the nine days. In the early hours of the tenth day Bharani Deepam in five agantams will be lit in Arunachaleswarar's Sannithi. In the evening, the Pancha Murthis will be brought to the Katchi Mandapam.

At dusk (Pradosha) the Karthigai day synchronizing with the full moon day, the deity, Ardhanareeswarar is taken out to this place with the five deepams, which are put in a big receptacle near the flug-stuff. At the same time the beacon light on the hill is lit. The huge concourse of devotees from all parts of our country in a million voice raise a cry simultaneously "Harohara to Annamalai" which will rend the air.
