Why people convert BST to PST time
- Scheduling a call from BST to PST: a 10:00 AM start in BST lands at 1:00 AM in PST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -9h gap: BST and PST 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 PST is 12:00 AM in BST.
- Keeping family and friends in sync: knowing that 8:00 PM in BST is 11:00 AM in PST 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 -9h gap is not.
- With a -9h gap there is no shared 9-to-5 window, so alternate the early start: one week BST takes the early slot, the next week PST 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 PST (Pacific Standard Time)
Pacific Standard Time (PST) covers the west coast of North America, including tech hubs like San Francisco and Seattle, and entertainment capital Los Angeles. The Pacific Time Zone is home to Silicon Valley and the world's largest technology companies. During summer, clocks advance to Pacific Daylight Time (PDT, UTC-07:00). PST is also observed in Baja California, Mexico.
Best time to call between BST and PST
With a -9h offset there is no overlap inside a normal 9 AM – 5 PM day. PST opens at 9:00 AM PST, which is 12:00 AM in BST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
BST and PST have no shared working hours because of the -9h gap. Teams need to alternate early starts or rely on asynchronous handovers.
BST is 9 hours behind PST (BST UTC+01:00 → PST UTC-08:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
