Ganesh chaturthi is the Hindu festival celebrated in honour of the elephant-headed god, Ganesha. Celebrations are traditionally held on the fourth day of the first fortnight (Shukla Chaturthi) in the month of Bhaadrapada in the Hindu calendar, usually August or September in the Gregorian calendar. The festival generally lasts ten days, ending on the fourteenth day of the fortnight (Anant Chaturdashi).
The festival is celebrated in public and at home. The public celebration involves installing clay images of Ganesha in public pandals (temporary shrines) and group worship. At home, an appropriately-sized clay image is installed and worshiped with family and friends. At the end of the festival, the idols are immersed (and dissolve) in a body of water such as a lake or pond.
It is celebrated throughout India, particularly in Maharashtra, Karnataka,Telangana, Tamil Nadu, Kerala, Andhra Pradesh, Goa, Odisha and other parts of western and southern India. Abroad, Ganesh Chaturthi is observed in the Terai region of Nepal and by the Hindu diaspora in the United States, Canada and Mauritius.
