British Summer Time is UTC+1. BST is also used for Bangladesh Standard Time (UTC+6). This page converts UK time.
The United Kingdom from the last Sunday in March to the last Sunday in October. The rest of the year the UK is on GMT (UTC+0).
PST: Pacific Standard Time
Pacific Standard Time is UTC−8. PST is also used for Philippine Standard Time (UTC+8) and sometimes for Pakistan Standard Time (UTC+5). This page converts US Pacific Time.
California, Washington, Oregon and Nevada, plus British Columbia in Canada and Baja California in Mexico. PT is the short form people use for the whole zone.
Most places on Pacific Time are on PDT (UTC−7) right now, not PST. People still say "PST" all year, so the times on this page follow the clocks and show PDT until 1 November 2026.
