Sharadotsav is an annual Hindu festival in South Asia that celebrates worship of the Hindu goddess Durga.
It refers to all the six days observed as Mahalaya, Shashthi, Maha Saptami, Maha Ashtami, Maha Nabami and Vijayadashami. The dates of Durga Puja celebrations are set according to the traditional Hindu calendar and the fortnight corresponding to the festival is called Devi Paksha, "Fortnight of the Goddess". Devi Paksha is preceded by Mahalaya, the last day of the previous fortnight Pitri Paksha, "Fortnight of the Forefathers"), and is ended on Kojagori Lokkhi Puja.
Durga Puja festival marks the victory of Goddess Durga over the evil buffalo demon Mahishasura. Thus, Durga Puja festival epitomises the victory of Good over Evil.
