Times follow London for BST and New Delhi for IST, using the IANA time zone database.
BST to IST time difference
IST is 4 hours 30 minutes ahead of BST for most of 2026, and 5 hours 30 minutes ahead of BST for about 155 days, because daylight saving time changes on different dates.
In 2026, UK Time switches to BST on March 29 and back to GMT on October 25. India Standard Time does not use daylight saving time.
