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 Standard Time (PST) 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.
