About PDT to GMT Conversion

Last updated: April 2026

Converting time between PST and GMT requires understanding their time zone offsets and any daylight saving time adjustments. PST (PDT) operates at UTC-7, while GMT (GMT) is set to UTC+1. This means GMT is 8 hours ahead PST. For example, when it's 3:57 AM PDT on May 30, 2026, it's 11:57 AM GMT in GMT. Both America/Los_Angeles and Europe/London observes daylight saving time, switching between PST (UTC-8) and PDT (UTC-7). Keep this in mind when converting times, especially during the spring and fall transition periods. Use this converter to quickly find the equivalent time in GMT for any time in PST, whether you're scheduling meetings, planning travel, or coordinating with teams across different time zones.
