United Kingdom's Timezone System Explained

The United Kingdom uses Greenwich Mean Time (GMT, UTC+0) in winter and British Summer Time (BST, UTC+1) in summer. England, Scotland, Wales, and Northern Ireland all observe the same change on the same schedule.

DST in 2025: clocks spring forward one hour at 1:00 AM on Sunday 30 March, and fall back one hour at 2:00 AM on Sunday 26 October. This follows the European Union convention of the last Sunday in March and last Sunday in October, which the UK retained after Brexit.

London is the world's reference timezone anchor — GMT was established here and UTC is calibrated against it. During BST (late March to late October), London aligns with Paris, Berlin, and Amsterdam (all on CEST at UTC+1). During GMT (late October to late March), London is one hour behind continental Europe.

Key gaps from London: New York is 5 hours behind GMT (4 hours behind BST). Los Angeles is 8 hours behind GMT (7 hours behind BST). Dubai is 4 hours ahead of GMT year-round. Mumbai (IST) is 5.5 hours ahead of GMT. Sydney (AEDT) is 11 hours ahead during Australian summer, 9 hours ahead during Australian winter.
