What is the Time Difference Between UK and Sri Lanka?

Sri Lanka operates on Indian Standard Time (IST), which is UTC +5:30 year-round. The UK, however, follows Greenwich Mean Time (GMT) in winter and British Summer Time (BST, GMT+1) in summer.

Here’s the breakdown:

• Winter (GMT in UK): Sri Lanka is 5 hours and 30 minutes ahead.

• Summer (BST in UK): Sri Lanka is 4 hours and 30 minutes ahead.

Example Time Comparison

12:00 PM (BST)	4:30 PM

Daylight Saving Time Impact

The UK observes Daylight Saving Time (DST), moving clocks forward by 1 hour in late March and back in late October. Sri Lanka does not follow DST, so the time difference changes twice a year.

• October to March: UK (GMT) = 5.5 hours behind Sri Lanka.
