London to Mumbai time difference
India Standard Time is 4.5 or 5.5 hours ahead of the UK, depending on the time of year, because India does not observe daylight saving. That half-hour offset is easy to miscalculate by hand, but it's handled automatically here.
Working hours: when London and Mumbai overlap
Taking a standard 09:00–17:00 working day in both places, the two cities currently share 09:00-12:30 in London , which is 13:30-17:00 in Mumbai . Anything scheduled inside that window lands in office hours at both ends.
The narrower the window, the more it pays to book the very start or end of it. Drag the timeline above to see the effect of moving a meeting by half an hour.

Daylight saving between London and Mumbai
Mumbai stays on the same offset all year, but London changes its clocks, so the gap between the two cities shifts during the year.

- 28 March 2027 — London puts its clocks forward an hour. Mumbai is then 4.5 hours ahead of London.
These dates come from the same time zone database your browser uses, so the converter above applies each change automatically on the day it happens.
Frequently Asked Questions: London & Mumbai
Can I compare London and Mumbai time directly?
Yes - this page loads London and Mumbai by default so you can see the current gap between them immediately. You can still change either city using the boxes above if you want a different comparison.
What do the common time zone abbreviations GMT, EST, and PST stand for?
These abbreviations identify a region's standard offset from UTC. GMT (Greenwich Mean Time) is the reference time for the UK, EST (Eastern Standard Time) covers the US East Coast such as New York and Washington, and PST (Pacific Standard Time) covers the US West Coast such as Los Angeles.
Does this time zone calculator automatically account for Daylight Saving Time (DST)?
Yes. TimeMatch.me reads the time zone database built into your own browser, which already knows whether any given city is currently observing daylight saving or standard time, and adjusts the calculation automatically all year round.
Does the site save my location or time data on a server?
No. TimeMatch.me runs entirely on the client side - every calculation happens on your phone or computer. Nothing about your location, your searches, or the cities you compare is sent to or stored on our servers.
Can I compare two specific time zones directly?
Yes. Besides the main comparator, dedicated pages such as the GMT to EST converter pre-load two common zones for a quick check, and you can always type any two cities into the boxes on any page.
