Kolkata (formerly Calcutta) is the capital of West Bengal and the largest city in eastern India, home to approximately 15 million people in the metro area. Like all Indian cities, it operates on Indian Standard Time (IST, UTC+5:30) — and notably, the IANA timezone identifier 'Asia/Kolkata' is named after this city. Kolkata served as the capital of British India from 1773 to 1911, making it the first metropolis of the colonial era on the subcontinent. The city was a major center of the Indian independence movement and is closely associated with Rabindranath Tagore, the first non-European Nobel laureate in Literature (1913). Mother Teresa devoted most of her life to serving Kolkata's poor through the Missionaries of Charity, which she founded here in 1950. The city is famous for its intellectual culture, literary festivals, football passion, and the Durga Puja festival — the largest street art and community festival in the world.
