About Kolkata
Kolkata is the capital of the Indian state of West Bengal and the main city of eastern India. Formerly the capital of British India, it is known for its colonial architecture, literary and film traditions, the Howrah Bridge across the Hooghly River and the Durga Puja festival. Its port and trading houses serve much of eastern India and neighbouring countries.
Kolkata uses India Standard Time, UTC+5:30, and India does not observe daylight saving. One zone covers the entire country, so sunrise and sunset in Kolkata come noticeably earlier than in Mumbai or Delhi on the same clock. The half-hour offset is easy to overlook: Kolkata is five and a half hours ahead of London in winter and four and a half in summer.
