About BST to PST Conversion

Last updated: April 2026

Converting time between GMT and PST requires understanding their time zone offsets and any daylight saving time adjustments. GMT (BST) operates at UTC+1, while PST (PST) is set to UTC-7. This means PST is 8 hours behind GMT. For example, when it's 8:13 AM BST on April 30, 2026, it's 12:13 AM PST in PST. Both Europe/London and America/Los_Angeles observes daylight saving time, switching between GMT (UTC+0) and BST (UTC+1). Keep this in mind when converting times, especially during the spring and fall transition periods.
