What Is the Time Difference Between PST and UK Time?
PST (UTC−8) is 8 hours behind UK time when the UK is on GMT (UTC+0). So 9:00 AM PST is 5:00 PM in the UK, and 12:00 PM PST is 8:00 PM in the UK. For a few weeks each year the gap is 7 hours, because the US and the UK change their clocks on different dates.
How to Convert PST to UK Time
You can convert Pacific Standard Time to UK time manually in three steps.
Step 1
Start With the PST Time
Take the time in PST. For example, 3:00 PM PST.
Step 2
Add 8 Hours
3:00 PM plus 8 hours gives 11:00 PM UK time (GMT).
Step 3
Adjust the Date if Needed
If the result passes midnight, the UK date is one day ahead of the PST date. For example, 6:00 PM PST is 2:00 AM the next day in the UK.
If the US is on Pacific Daylight Time (PDT, UTC−7) and the UK is on British Summer Time (BST, UTC+1), the difference is still 8 hours. If only one of them is on daylight saving time, the difference is 7 hours.

PST vs PDT and GMT vs BST: Why the Time Difference Changes
Both regions move their clocks for daylight saving time, but not on the same dates. The US Pacific zone switches between Pacific Standard Time (PST, UTC−8) and Pacific Daylight Time (PDT, UTC−7). The UK switches between Greenwich Mean Time (GMT, UTC+0) and British Summer Time (BST, UTC+1).
The US changes its clocks on the second Sunday of March and the first Sunday of November. The UK changes on the last Sunday of March and the last Sunday of October. Because the dates differ, the time gap shifts briefly. Here is how it works in 2026.
| Period (2026) | US Pacific Time | UK Time | Time Difference |
|---|---|---|---|
| Jan 1 – Mar 7 | PST (UTC−8) | GMT (UTC+0) | 8 hours |
| Mar 8 – Mar 28 | PDT (UTC−7) | GMT (UTC+0) | 7 hours |
| Mar 29 – Oct 24 | PDT (UTC−7) | BST (UTC+1) | 8 hours |
| Oct 25 – Oct 31 | PDT (UTC−7) | GMT (UTC+0) | 7 hours |
| Nov 1 – Dec 31 | PST (UTC−8) | GMT (UTC+0) | 8 hours |
Tip: Be careful when scheduling meetings in late March and late October. The one-hour shift catches many teams off guard.
Best Time for a Meeting Between California and the UK
With an 8-hour gap, the working days overlap for only a short window. The UK workday ends just as the US West Coast morning begins.
| Pacific Time (PST) | UK Time (GMT) | Suitability |
|---|---|---|
| 7:00 AM – 8:00 AM | 3:00 PM – 4:00 PM | Good (early start for the US) |
| 8:00 AM – 9:30 AM | 4:00 PM – 5:30 PM | Best overlap |
| 9:30 AM – 10:00 AM | 5:30 PM – 6:00 PM | Fair (late for the UK) |
| 10:00 AM onward | 6:00 PM onward | Outside UK office hours |
A standard 9:00 AM to 5:00 PM workday in PST runs from 5:00 PM to 1:00 AM the next day in the UK.

In winter it uses Greenwich Mean Time (GMT, UTC+0), and in summer it uses British Summer Time (BST, UTC+1). In the IANA database it is listed as Europe/London. Clocks go forward on the last Sunday of March and back on the last Sunday of October.
