Converting between US Pacific (PT) and UK (GMT/BST)
US Pacific (PT) covers Los Angeles, San Francisco, Seattle; UK (GMT/BST) covers London, Dublin, Lisbon. Because time-zone offsets shift with daylight saving, the gap between them is not a single fixed number — both zones change their clocks, on different dates, so the difference moves twice a year. The converter above reads today's real offsets from your browser's timezone data, so the live difference and the overlap table are always correct for the current date.
To schedule across the two, use the green rows of the overlap table: they mark the hours that land inside a 9am–5pm working day on both sides. When there's little or no overlap — common for zones more than about ten hours apart — the practical fix is for one party to take the call early or late, or to alternate who does so across recurring meetings.
Frequently asked questions
What is the time difference between PST and GMT?
It changes across the year because at least one of these zones observes daylight saving time. The live converter above shows the exact current difference and updates every second — always convert a specific date's time rather than a remembered number.
When is the best time to schedule a meeting between US Pacific (PT) and UK (GMT/BST)?
The overlap table above highlights the hours that fall within 9am–5pm in both zones for today's offsets. Pick a slot from the green "both working" rows; if there's no overlap, one side takes an early-morning or late-evening call.
Does this converter handle daylight saving time?
Yes — it reads each zone's DST rules from your browser's built-in IANA timezone database, so the difference is correct whether or not either side is currently on summer time. US Pacific (PT) observes DST; UK (GMT/BST) observes DST.
Is my location or time data sent anywhere?
No — the conversion uses your device's own clock and the timezone data already in your browser. Nothing is transmitted, and the page works offline after it loads.
Why might GMT show a different date than PST?
When the offset is large enough, one zone can already be on the next calendar day (or still on the previous one) while the other hasn't rolled over. The live clocks above show each zone's weekday so you can see when they differ.
