About GMT and IST
Time Difference
India Standard Time (IST) is 5 hours and 30 minutes ahead of Greenwich Mean Time (GMT). When it's 12:00 PM (noon) in London, it's 5:30 PM in Mumbai.
Best Time for Meetings
For meetings between UK and India, the best overlap is typically between:
- •8:00 AM - 11:00 AM GMT (1:30 PM - 4:30 PM IST) - Good for UK morning / India afternoon
- •2:00 PM - 5:00 PM GMT (7:30 PM - 10:30 PM IST) - UK afternoon / India evening
Daylight Saving Time
The UK observes British Summer Time (BST) from late March to late October, moving clocks 1 hour forward. India does not observe daylight saving time, so the time difference changes to 4 hours and 30 minutes during BST.
