UK time is Greenwich Mean Time (GMT, UTC+0) in winter and British Summer Time (BST, UTC+1) from the last Sunday in March to the last Sunday in October.
Pacific Time follows the clock in Los Angeles: Pacific Standard Time (PST, UTC−8) in winter and Pacific Daylight Time (PDT, UTC−7) during US daylight saving time.
PST is often used loosely for Pacific Time all year. In summer the correct abbreviation is PDT; the converter uses whichever applies on your date.
PDT is 8 hours behind BST for most of the year (210 days in 2026). The gap is 7 hours for about 4 weeks in 2026.
California uses Pacific Time. PDT is 8 hours behind BST for most of the year (210 days in 2026). The gap is 7 hours for about 4 weeks in 2026. Type any UK time time into the UK time to PST converter to see the California time for any date.
9:00 AM BST or GMT is 1:00 AM PDT or PST for most of the year (337 days in 2026). 9:00 AM GMT is 2:00 AM PDT for about 4 weeks in 2026.

Working days of 9 AM to 5 PM do not overlap. The least disruptive slot is around 4:30 PM BST, which is 8:30 AM PDT while BST and PDT apply.
Both zones change their clocks, on their own dates, so the gap can shift during the year. The next change is on Sunday, November 1, 2026 in Pacific Time.
