What PST and BST Actually Are

PST — Pacific Standard Time

Los Angeles, San Francisco, Seattle, Las Vegas, Vancouver. Standing at UTC-8:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to PST. The Philippines occasionally uses PST for Philippine Standard Time (UTC+8); PHT is the clearer label for that.

California voted in 2018 to move to permanent daylight time, but the change needs an act of Congress and has never happened, so PST is still the winter standard.

BST — British Summer Time

London, Manchester, Birmingham, Glasgow, and the rest of the UK from late March to late October. Standing at UTC+1:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, October 25, 2026, to GMT. BST also stands for Bangladesh Standard Time (UTC+6). BDT is the clearer label for that one.

British Summer Time began in 1916 as a wartime fuel-saving measure and has run every year since, making it one of the oldest continuous daylight saving schemes in the world.

What This Means in Practice

The date changes mid-working-day

For 1 of the eight hours in a normal PST working day, the equivalent BST time falls on a different calendar date. Anything scheduled in that stretch needs the date checked as well as the time, or a Tuesday call quietly becomes a Wednesday one at the other end.

Both sides change clocks, on different dates

Both regions observe daylight saving but do not switch on the same day, so for a week or two each spring and fall the gap between them is an hour different from the rest of the year. Those short windows are where recurring invitations quietly break.
