Durga Pooja is a major Hindu festival celebrating Goddess Durga. It is observed primarily during the month of October according to the Hindu calendar. The festival typically lasts five days and is celebrated with great devotion in India and Bangladesh, especially in regions like West Bengal, Bihar, Jharkhand, Odisha, Tripura, and Assam.

Durga Pooja commemorates the victory of good over evil, symbolized by Goddess Durga's triumph over the demon king Mahishasura. The festival includes fasting, feasting, elaborate worship ceremonies, decorating homes and temples, wearing new clothes, and organizing cultural events.

The festival begins with the installation of the idol of Goddess Durga, followed by nine days of worship. On the final day, a grand procession takes place, ending in the immersion of the idol in a river or water body. Durga Pooja is a time of joy, faith, and community celebration among Hindus.
