Theyyam season starts from the tenth day of the Malayalam month of Thulam (usually falls during October, and known as paththaam-udayam) and lasts up to seven months till the middle of Edavam month (typically late May and June). The last Kaliyaattam for the season is performed at Madayi Kavu and Kalarivathukkal Bhagavathy Temple, both being the family shrines of Kolathiri royal family.
