PST to GMT time difference
Right now UK is 8 hours ahead of US Pacific Time: when it is 9:00 AM in US Pacific Time (PDT), it is 5:00 PM in UK (BST). The difference is not fixed. US Pacific Time and UK change the clocks twice a year, so from October 25, 2026 the gap becomes 7 hours, and from November 2, 2026 it goes back to 8 hours.
PT, PST and PDT
PT means Pacific Time, whatever the season. It is PST (Pacific Standard Time, UTC-8) from early November to mid-March and PDT (Pacific Daylight Time, UTC-7) the rest of the year. Today it is PDT. People often write "EST" all year when they mean Eastern Time; the times on this page are correct either way.

Scheduling tips
With a gap of 8 hours, working hours barely overlap. Early morning in one place is evening in the other, so calls usually work best at the start or end of the day. When you share a time, write the zone with it, such as "9:00 AM PST", and remember that a time near midnight can fall on a different date on the other side.
