Answer:
Durga Puja, held in September–October, is the biggest and most important festival of West Bengal as well as of Kolkata. It marks the victory of ten-armed goddess Durga over the buffalo demon Mahishasur and signifies the victory of good over evil. The festival commences on Mahalaya, a week before the actual Puja celebrations begin on Sashthi and continue through Saptami, Ashtami, Navami and Vijaya Dashami, when the festival comes to an end. Pandals are set up and idols of goddess Durga and her four children - Lakshmi, Saraswati, Kartik, Ganesh are worshipped and displayed for five days across the state, especially in Kolkata. Some 3000 pandals are erected throughout Kolkata and its suburbs. Pujas are also conducted in sizeable number of family households. Elaborate rituals are performed by priests amid sound of drums (dhaak), conch shell (shaankh) and bells, and many devotees join in the prayers. Although the root of Durga Puja is essentially religious, the festival has slowly changed into more of a social carnival than a religious festival, where people from other religious or ethnic backgrounds freely participate in the festivity. It has become Kolkata's biggest public spectacle, glamorous art event and consumerist carnival. The city is decked up with lighting decorations.
