PST to GMT

PST and GMT across the year

Both zones change their clocks on the same dates, so the gap between them never moves — London is 8 hours ahead of Los Angeles all year. Note that this is a fixed difference, not a fixed offset: both cities still shift by an hour twice a year, so a time expressed in UTC will change even though the gap between these two does not.

PST: Pacific Time shifts to PDT (UTC−7) during daylight saving and back to PST (UTC−8) in winter. Most people who search for PST mean whatever Pacific Time is right now, which is what this shows.

GMT: The UK is on GMT in winter and BST (UTC+1) in summer, so 'GMT' and 'London time' are the same thing for only half the year. Strictly, GMT never shifts — if you need a fixed reference, use UTC.

Scheduling between Los Angeles and London

The workable window is 9:00 am to 10:00 am in Los Angeles — 5:00 pm to 6:00 pm in London. That is 1 hour out of a nine-hour working day, and everything outside it costs somebody their morning or their evening.

Three hours or fewer is a tight window, and it fills up fast once both sides have their own internal meetings in it. If this pair is a regular working relationship, it is worth treating that window as protected time — the scarcest shared resource the two teams have — rather than letting it be consumed by whatever gets booked first.

The two edges behave differently. Booking at 9:00 am Los Angeles time means London is late in its afternoon and may be winding down; booking at 9:00 am means Los Angeles is mid-afternoon while London is closer to the end of the day. Where the decision matters, give the later-in-the-day side the earlier slot.

If you are the one in Los Angeles

London is ahead of you, which means their day is already ending as yours gets going. By the time you are at your desk at 9:00 am, it is 5:00 pm there — so anything you send in your morning arrives in their evening, after they have stopped. The practical consequence is that your late afternoon is dead time for anything needing a reply from London: they are asleep, and you will not hear back until your next morning.

So the discipline that pays off is front-loading. Anything London needs from you should go out early in your day while they are still working; anything you need from them should be asked for before you leave, so it is waiting when you return. Treat their evening as the deadline, not yours.
