Ganesh Chaturthi is celebrated as the birthday of Lord Ganesha. The festival is also known as Vinayaka Chaturthi and Ganeshotsav. According to Hindu calendar it is celebrated on the fourth day of the bright half of Bhadrapad. During the Ganesh Chaturthi festival, idols are made in great numbers. These are usually made out of clay or metal in all sizes; some of them are even as big as 20 ft. People purchase deities of Lord Ganesha and put them in their homes and worship them for one to ten days. After this the deities are taken out majestically, through the streets and are immersed into a river, sea or a well (especially in Maharashtra). Cultural feasts are also organized with main features like classical music and dance performances, folk dances, poetry recitations and film festivals.
