Understanding the Time Difference Between London and Mumbai
Mumbai operates on the Asia/Kolkata timezone, which is 5.5 hours ahead of London's Europe/London timezone. This means when it's noon in London, it's 17:30 in Mumbai.
Best Hours for Business Communication
The optimal window for scheduling calls or meetings between London and Mumbai is when both cities are within their standard business hours (9:00-17:00 in London and 10:00-19:00 in Mumbai).
Based on this overlap, we recommend scheduling meetings during the shared business hours window where both cities are within their typical 9:00–17:00 workday.
Daylight Saving Time Considerations
London observes Daylight Saving Time, typically adjusting clocks forward in spring and back in fall. During DST transitions, the time difference may temporarily change by one hour. Always verify the current time difference during March/April and October/November.
