Scheduling Tips

Schedule at 4:00-5:00 PM GMT / 8:00-9:00 AM PST for the sweet spot where both teams are alert and available.
UK managers can batch async reviews and decisions in the morning (9:00 AM-12:00 PM GMT) and save the afternoon for live calls with the West Coast.
Watch the DST transition weeks in March and October — set calendar reminders to verify recurring meeting times have not shifted.

Frequently Asked Questions

What is the time difference between GMT and PST?

GMT (UTC+0) is 8 hours ahead of PST (Pacific Standard Time, UTC-8). When it is 5:00 PM GMT, it is 9:00 AM PST. From mid-March to early November, Los Angeles uses PDT (UTC-7), so GMT is 7 hours ahead.

When does the GMT-PST offset change?

GMT never changes, so the offset changes only on US dates. The US moves to PDT on the second Sunday in March, and the gap shrinks to 7 hours. The US returns to PST on the first Sunday in November, and the gap returns to 8 hours. London time is different: UK clocks use BST in summer, so London and Los Angeles stay 8 hours apart for most of the year.

What is 9 AM GMT in PST?

9:00 AM GMT is 1:00 AM PST. The UK morning falls in the middle of the night on the West Coast. Morning GMT meetings are not practical for PST attendees.

What is 3 PM GMT in PST?

3:00 PM GMT is 7:00 AM PST. This catches the very start of the West Coast workday and is the earliest feasible meeting time for both sides.

What is 5 PM GMT in PST?

5:00 PM GMT is 9:00 AM PST. The UK is ending its day while LA is starting. This is the most popular slot for transatlantic meetings between London and the West Coast.

What is the best meeting time for GMT and PST teams?

The prime window is 3:00-5:00 PM GMT / 7:00-9:00 AM PST. UK teams are in their afternoon; West Coast teams are in their morning. Outside this window, one side is out of hours.

Does BST change the gap with PST?

During BST (UTC+1, late March to late October), the UK is 1 hour further ahead. If the US is also on PDT (UTC-7), the net gap stays at 8 hours. The gap only shifts during the 2-3 week spring window and the ~1 week fall window when only one side has changed.
