The most famous festivals held by Keralites are Onam, the harvest festival and Vishu, the Malayalam Calendar New Year. In addition to these, temples as well as churches hold festivals in several days of the year. A common tradition in all these festivals is the hosting of the holy flag, which is brought down on the last day of the festival. Some temple festivals are called poorams, and the most famous one among these is 'Thrissur Pooram'. The main attractions of poorams are firecrackers, traditional dance forms like 'Theyyam, Kathakali, Chakyar Koothu etc.'. Festivals are locally known as "utsavams" .
