According to Hindu calendar listings, Durga Puja’s key days in 2026 fall between October 16 and October 20. Mahalaya, which marks the symbolic beginning of Durga’s journey home, falls on September 26, followed by Maha Panchami on October 16, Maha Sashti and Maha Saptami on October 17, Maha Ashtami and Maha Navami on October 19, and Vijaya Dashami closing the festival on October 20. Predominantly celebrated across West Bengal, Assam, Tripura, Odisha, and Bihar, the festival marks Goddess Durga’s victory over the demon Mahishasura, alongside worship of Saraswati, Lakshmi, Ganesha, and Kartik. Kolkata transforms completely during this stretch, with elaborate pandals showcasing artistic idols and drawing visitors from across the country.
