GMT to PST Converter

Pacific Standard Time is UTC−8 and Pacific Daylight Time is UTC−7. GMT here is the fixed UTC+0 reference, Etc/GMT in the IANA time zone database, so the gap is eight hours in the US winter and seven in the US summer. The West Coast moves forward on the second Sunday in March and back on the first Sunday in November, the dates set out by the US Department of Transportation.

With a gap that large, the GMT morning is the West Coast night. Anything before 08:00 GMT in winter, or 07:00 GMT in summer, is still the previous day in Los Angeles.

If you work with people in the UK, both clocks move: London goes to BST on the last Sunday in March and back on the last Sunday in October. For most of the year London is eight hours ahead of Los Angeles, and seven hours for a few weeks in March and late October.

That leaves almost no shared office time. 8:00 AM in San Francisco is 4:00 PM in London, so the usual slot is the first hour of the California day. Anything after 10:00 AM Pacific reaches the UK after 6:00 PM.

Times in the cards assume the usual eight-hour London gap. See the live Vancouver clock, or convert back with PST to GMT.
