Our free GMT to PST converter instantly translates Greenwich Mean Time into US Pacific Time — the London-to-Los-Angeles conversion. With an eight-hour gap, overlapping work hours are narrow, so this tool helps you find the few windows that work for both the UK and the US West Coast.

GMT to PST Time Difference

Pacific Time is well behind GMT; the exact gap depends on daylight saving on both sides: (Offsets follow the IANA Time Zone Database.)

Standard time (GMT vs PST): PST is 8 hours behind GMT in winter. 12:00 PM GMT is 4:00 AM PST.
DST timing: the UK and US change clocks on slightly different dates, so the gap can briefly be 7 hours in spring and autumn before settling back. The converter applies the correct offset for the date.
In UK summer, London runs on BST (UTC+1), so “London to Los Angeles” becomes a BST-to-PDT conversion of about 8 hours.

Best Times to Schedule London ↔ Los Angeles Meetings

4:00–6:00 PM GMT = 8:00–10:00 AM PST — UK late afternoon meets the start of the LA day, the main overlap.
5:00–7:00 PM GMT = 9:00–11:00 AM PST — end of the UK day for a mid-morning West Coast call.

Frequently Asked Questions

How many hours ahead is GMT from PST?

GMT is 8 hours ahead of PST during standard time, so 12:00 PM GMT is 4:00 AM PST. Near daylight-saving changes the gap can be 7 hours for a short period.

What is the best time for a London–LA call?

UK late afternoon (4:00–6:00 PM GMT) overlaps the start of the Los Angeles workday (8:00–10:00 AM PST). That is the most practical window given the 8-hour gap.

Is GMT to PST the same as UTC to PST?

For conversion, yes — GMT and UTC share a zero offset, so both put noon at 4:00 AM PST in winter. UTC is the standard used by software and servers.
