GMT is 7 hours ahead of Pacific Time from March to November, and 8 hours ahead the rest of the year.

About these time zones
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.
GMT: Greenwich Mean Time
Greenwich Mean Time is UTC+0.
The same time as UTC. The UK, Ireland and Portugal use GMT in winter, then switch to summer time (BST in the UK) from late March to late October. Iceland and much of West Africa stay on GMT all year.
How the difference changes
Right now GMT is 7 hours ahead of PDT. From 1 November 2026, when US clocks go back, the difference becomes 8 hours. From 14 March 2027, when US clocks go forward, the difference becomes 7 hours.
