About Mumbai time
Mumbai runs on India Standard Time, a single nationwide zone offset by an unusual half hour — five and a half hours ahead of UTC.
India uses one time zone for the entire subcontinent, and its UTC+5:30 offset is one of the few in the world set on the half hour — a compromise between the country’s east and west. Mumbai, home to the Bombay Stock Exchange (Asia’s oldest) and to Bollywood, effectively sets the financial and entertainment clock for India. The offset means calls with the U.S. and Europe rarely land on a tidy hour boundary.
