GMT never changes for daylight saving time, but Pacific Time does, so the gap moves by an hour twice a year. The table below always shows the right one for your date.
Convert Greenwich Mean Time (GMT) to Pacific Daylight Time (PDT) for any date and time.
Pacific Time is 7 hours behind GMT from March to November, and 8 hours behind the rest of the year.
Right now GMT is UTC+0 and the West Coast is on PST (UTC−8). Pacific Time switches to daylight saving time on 14 March 2027.
9:00 am to 5:00 pm GMT is 1:00 am to 9:00 am PST.

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.
Pacific Daylight Time is UTC−7.
California, Washington, Oregon and Nevada, plus British Columbia in Canada, from March to November. The rest of the year the zone is on PST.
PDT isn't in use at the moment: Pacific Time is on PST (UTC−8) until 14 March 2027. The times on this page follow the clocks, so they show PST.
