PST (Pacific Standard Time) is 8 hours behind GMT (Greenwich Mean Time). During PDT/BST, when both observe daylight saving, PST is 7 hours behind GMT.
The best time to call from GMT to PST is between 4:00 PM and 8:00 PM GMT, which corresponds to 8:00 AM to 12:00 PM PST. This ensures both parties are within standard business hours.
Usually the difference stays at 8 hours because both regions observe DST. However, there are brief periods when the difference is 7 hours, as the US and UK change their clocks on different dates.
GMT cities include London, Manchester, Birmingham, Liverpool, and Edinburgh. PST cities include Los Angeles, San Francisco, Seattle, San Diego, and Portland.
The 8-hour difference exists because London and the US West Coast are separated by approximately 5,400 miles. GMT is at the Prime Meridian (0° longitude), while PST is at UTC-8.
