Durga Puja, also referred to as Durgotsava (Festival of Durga), is a famous Hindu festival marked by worship of Mother Goddess Durga over the last five days of Navratri, in the Ashwin month of the Hindu calendar. These five days are observed as Shashthi, Saptami, Ashtami, Navami and Vijayadashami. The festivities culminate on the tenth day on Vijayadashami when Durga idols are carried out in grand procession and immersed in the river or other water bodies.
