PST (Pacific Standard Time) is 8 hours behind GMT (Greenwich Mean Time). This means when it's 12:00 PM in London (GMT), it's 4:00 AM in Los Angeles (PST).
The best time to call from GMT to PST is during overlapping business hours. For GMT callers, schedule between 12:00 PM - 5:00 PM GMT to ensure both parties are within standard business hours.
The time difference may change during daylight saving transitions if one region observes DST while the other doesn't. Greenwich Mean Time (UTC+0 (GMT) / UTC+1 (BST)) and Pacific Standard Time (UTC-8 (PST) / UTC-7 (PDT)) may have different DST schedules.
GMT includes cities like London. PST includes cities like Los Angeles. Both time zones cover important business and cultural centers.
In 2025, DST in North America starts on March 9 at 2:00 AM and ends on November 2 at 2:00 AM. Other regions may have different DST schedules or not observe DST at all.
