About these time zones

BST: Greenwich Mean Time

British Summer Time (BST). The United Kingdom from late March to late October (UTC+1). In winter the UK returns to GMT. BST is also sometimes used for Bangladesh Standard Time (UTC+6); this page means British time.

Sunday, March 28, 2027: clocks go forward 1 hour at 1:00 AM local time (UTC+0 → UTC+1).

GMT: Coordinated Universal Time

Greenwich Mean Time (GMT). Equal to UTC for everyday use. The United Kingdom, Ireland, Portugal, Iceland and much of West Africa use GMT in winter or all year; the UK switches to BST (UTC+1) in summer.

No clock change is scheduled; the offset stays the same all year.
