BST vs PST — London to West Coast

BST is UTC+1, the UK's summer time (late March–late October). PST is UTC-8, US West Coast winter time. In summer both shift: BST (UTC+1) vs PDT (UTC-7) = 8 hours apart.

The London–Silicon Valley gap is 8 hours in summer. The standard overlap: 5:00–7:00 PM BST = 9:00–11:00 AM PDT.

Frequently Asked Questions

How many hours is BST ahead of PST/PDT?

BST (British Summer Time, UTC+1) is 8 hours ahead of PST (UTC-8) in US winter. During US Daylight Saving Time (PDT, UTC-7), BST is 8 hours ahead. Both the UK (BST) and US West Coast (PDT) observe summer time simultaneously from mid-March to late October, making the gap consistently 8 hours during that period.

What is 9 AM BST in PST/PDT?

9:00 AM BST (London summer) is 1:00 AM PST the same day, or 2:00 AM PDT. A 9 AM London morning call is the middle of the night in Los Angeles. The practical overlap window is 5:00–7:00 PM BST = 9:00–11:00 AM PDT.

What is the best time to schedule a London–Los Angeles meeting in summer?

In summer when London uses BST (UTC+1) and LA uses PDT (UTC-7), the best overlap is 5:00–7:00 PM BST = 9:00–11:00 AM PDT. This is late afternoon for London and morning for Los Angeles.
