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.
Pacific Time is well behind GMT; the exact gap depends on daylight saving on both sides: (Offsets follow the IANA Time Zone Database.)
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.
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.
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.
PST is 8 hours behind GMT year-round. 100% free, no registration, and fully private — every conversion happens in your browser.
Uses the IANA database for Europe/London and America/Los_Angeles, so daylight saving is applied automatically — no manual offset math.
Convert GMT to PST the moment you pick a time. No signup, no ads in your way, nothing to install.
Spot the wide 8 hours gap between London and Los Angeles so you can plan async or off-hours calls.
Every conversion runs locally in your browser using your device clock. Your dates and times never touch a server.
