GMT to PST Time

GMT covers Reykjavik and Accra, and the reference for every other zone. PST covers Los Angeles, San Francisco, Seattle, Las Vegas and Vancouver.

Working days overlap between 16:00 and 18:00 GMT, which is 09:00–11:00 in PST. That window is where calls land without anyone working late.

The clocks do not change on the same day, so a recurring meeting can shift by an hour in March and again in November. Check any standing call in the two weeks after each change.

Pacific Time (Los Angeles) is 8 hours behind of GMT / UTC between November and March, and 7 hours behind the rest of the year.

1. Take the GMT time you want to convert.
2. Subtract 8 hours between autumn and spring, or 7 hours during daylight saving.
3. Roll the date forward or back if the result crosses midnight.

The gap changes because the two places start and end daylight saving on different dates — for a few weeks each spring and autumn the difference is an hour off its usual value. The converter above uses the live IANA time zone database, so it is right on those days too.

Zone details: GMT is +0 in winter and summer (UTC), PST is −8 in winter and −7 in summer.
