Convert a specific time from BST to PST
Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.
What is the time difference between BST and PST?
Pacific Time is 8 hours behind UK Time. To go from BST to PST you subtract 8 hours. That gap is not fixed. Across 2026 the distance between these two zones takes 2 different values, from 7 hours to 8 hours, because the two sides change their clocks on different dates. This page recomputes it rather than assuming.

What are the best hours to schedule a call between BST and PST?
No hour of the standard 9:00 am to 5:00 pm working day falls inside working hours on both sides. UK and Pacific are 8 hours apart, which is too far for an overlap, so somebody has to take a call outside their own working day. The least painful options are below, ranked by how close both sides sit to the middle of the afternoon.
| BST | PST | Working hours | Note |
|---|---|---|---|
| 3:00 pm | 7:00 am | BST only | afternoon in UK, early morning in Pacific |
| 4:00 pm | 8:00 am | BST only | afternoon in UK, mid morning in Pacific |
| 5:00 pm | 9:00 am | PST only | evening in UK, mid morning in Pacific |
Does daylight saving change BST to PST?
UK Time is currently on BST and changes next on Sunday, October 25, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC+1 to UTC+0.
Pacific Time is currently on PDT and changes next on Sunday, November 1, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC-7 to UTC-8.
Because the two sides do not move together, the answer to this conversion changes during the year. The United States changes on the second Sunday in March and the first Sunday in November, while the United Kingdom and European Union change on the last Sunday in March and the last Sunday in October. Those dates are weeks apart, which opens a window each spring and autumn where the usual gap is an hour out. The table above is built for today, not for an average day.
Is BST ahead of or behind PST?
BST is ahead of PST by 8 hours: when it is 12:00 pm in UK, it is 4:00 am in Pacific. One wrinkle worth knowing: GMT and BST are two names for the same zone, not two zones. UK Time reads GMT in winter and BST in summer. When somebody types "bst to pst" they nearly always mean the zone rather than the literal winter offset, so this page resolves BST to Europe/London and PST to America/Los_Angeles and applies whichever offset is genuinely in force on the day.
UK Time covers London, Cardiff, Edinburgh and Dublin. Pacific Time covers Los Angeles, San Francisco, Seattle and Vancouver. The identifiers behind them are Europe/London and America/Los_Angeles, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
