Current time in Mumbai

India Standard Time and its half hour

Mumbai uses India Standard Time (IST), five and a half hours ahead of UTC, all year. The half hour catches out many first-time callers: when it is noon in London in winter, it is 17:30 in Mumbai, and 16:30 during British Summer Time. India does not change its clocks, so the gap to New York is ten and a half hours in the northern winter and nine and a half in summer.

Bombay Time outlived the Raj

India Standard Time was introduced in 1906, but Bombay, as the city was then called, refused to give up its own local time. Bombay Time ran 4 hours and 51 minutes ahead of Greenwich, 39 minutes behind the new national standard, and the two were used side by side for decades. The city’s separate time was only dropped in 1955, eight years after independence.

When India’s markets are open

Mumbai is home to the National Stock Exchange and the Bombay Stock Exchange. Both trade from 09:15 to 15:30 local time, Monday to Friday, which is 03:45 to 10:00 UTC. For an investor in London the session therefore ends at 10:00 in winter and 11:00 in summer. In New York it runs overnight, from late evening to early morning, and in Singapore it fills the day from 11:45 to 18:00.
