PST to GMT Converter – Convert Pacific Time to GMT

GMT is 8 hours ahead of PST, so to convert mentally, add 8 hours to your PST time. For example: 9:00 AM PST = 5:00 PM GMT. Our converter automatically adjusts for Daylight Saving Time so you always get the right result.

GMT (Greenwich Mean Time, UTC+0) is 8 hours ahead of PST (Pacific Standard Time, UTC-8) during standard time. For example, 9:00 AM PST = 5:00 PM GMT. During DST periods, this difference changes by 1 hour when one or both zones observe Daylight Saving Time — our converter automatically applies the correct offset for any date you select.

GMT is 8 hours ahead of PST, so standard 9–5 business hours do not overlap. The most practical window is early morning in PST (7–9 AM), which falls in the evening in GMT — for example, 7:00 AM PST = 3:00 PM GMT. Use our meeting planner to find the exact time for your date, especially around DST transitions.

Yes. PST (Pacific Standard Time) observes Daylight Saving Time. Clocks spring forward to PDT (UTC-7) on the second Sunday in March, and fall back to PST on the first Sunday in November. During the DST period, the difference with GMT changes by 1 hour. Our converter always uses the current offset for the date you select.

Major cities in the PST (Pacific Standard Time, UTC-8) timezone include: Los Angeles, San Francisco, Seattle, Portland, Las Vegas, Vancouver. These cities switch to PDT (UTC-7) from the second Sunday in March to the first Sunday in November.

Major cities in the GMT (Greenwich Mean Time, UTC+0) timezone include: London (winter), Dublin (winter), Edinburgh, Reykjavik, Accra, Dakar. These cities switch to BST (UTC+1) from the last Sunday in March to the last Sunday in October.

GMT is 8 hours ahead of PST. Because PST and GMT are 8 hours apart, there is no standard business-hour overlap — plan for one side to take an early morning or late evening call. Always include both local times in calendar invites (for example, "2:00 PM PST / 10:00 PM GMT GMT"). Double-check around March and November (or March/October for European zones) when DST transitions can shift the offset by 1 hour.
