What is GMT in PST?
Pacific Time is 7 hours behind
Greenwich Mean Time is on UTC+0:00 and Pacific Time is on UTC−7:00 right now. Pacific Time is on daylight saving, so its clocks read PDT. The gap changes during the year — see below.

When the difference changes
Greenwich Mean Time and Pacific Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:
- Now – November 1, 2026Pacific Time is 7 hours behind
- November 1, 2026 – March 14, 2027Pacific Time is 8 hours behind
- March 14, 2027 – onwardsPacific Time is 7 hours behind
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
Daylight saving
