Times follow UTC / GMT for GMT and London for BST, using the IANA time zone database.
GMT to BST time difference
BST is 1 hour ahead of GMT for most of 2026, and the same time as GMT for about 155 days, because daylight saving time changes on different dates.
Greenwich Mean Time does not use daylight saving time. In 2026, UK Time switches to BST on March 29 and back to GMT on October 25.
