Why people convert BST to PDT time
- Scheduling a call from BST to PDT: a 10:00 AM start in BST lands at 2:00 AM in PDT, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -8h gap: BST and PDT have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in PDT is 1:00 AM in BST.
- Keeping family and friends in sync: knowing that 8:00 PM in BST is 12:00 PM in PDT makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM BST" is unambiguous; "3 PM" across a -8h gap is not.
- With a -8h gap there is no shared 9-to-5 window, so alternate the early start: one week BST takes the early slot, the next week PDT does.
About BST (British Summer Time)
British Summer Time (BST) is the daylight saving period in the United Kingdom, when clocks move one hour forward from Greenwich Mean Time (GMT, UTC+00:00) to UTC+01:00. It runs from the last Sunday in March to the last Sunday in October. England, Scotland, Wales and Northern Ireland all follow it, along with the Isle of Man and the Channel Islands of Jersey and Guernsey. During BST, London is one hour ahead of UTC, four hours ahead of New York on Eastern Daylight Time, and five hours ahead of New York once the United States returns to Eastern Standard Time in November. BST is also used to abbreviate Bangladesh Standard Time (UTC+06:00), which is listed separately on this site.
About PDT (Pacific Daylight Time)
Pacific Daylight Time (PDT) is observed from March to November on the Pacific coast. During PDT, the west coast is 7 hours behind UTC and only 2 hours behind the east coast's EDT.
Best time to call between BST and PDT
With a -8h offset there is no overlap inside a normal 9 AM – 5 PM day. PDT opens at 9:00 AM PDT, which is 1:00 AM in BST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
BST and PDT have no shared working hours because of the -8h gap. Teams need to alternate early starts or rely on asynchronous handovers.
BST is 8 hours behind PDT (BST UTC+01:00 → PDT UTC-07:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
