Why people convert PST to BST time
- Scheduling a call from PST to BST: a 10:00 AM start in PST lands at 7:00 PM in BST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +9h gap: PST and BST 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 BST is 6:00 PM in PST.
- Coordinating a PST-based team with BST contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM PST" 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 PST takes the early slot, the next week BST does.
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.
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.
Best time to call between PST and BST
With a +9h offset there is no overlap inside a normal 9 AM – 5 PM day. BST opens at 9:00 AM BST, which is 6:00 PM in PST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
PST and BST have no shared working hours because of the +9h gap. Teams need to alternate early starts or rely on asynchronous handovers.
PST is 9 hours ahead of BST (PST UTC-08:00 → BST UTC+01:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
