PST to GMT converter
GMT is 8 hours ahead of PST. The gap is stable for most of the year and wrong for about three weeks of it. The full hour-by-hour table is below, and it reads perfectly well with JavaScript turned off. No account, no email address.
The live converter needs JavaScript. The conversion table below works without it, and so does everything else on this page.
Nothing leaves this browser. There is no account and nothing is uploaded. Offsets are fixed values, not a live feed. See the daylight saving note below.

PST to GMT is not the same gap all year
The gap is stable for most of the year and wrong for about three weeks of it. The United States and Europe both use daylight saving, and they do not start and finish it on the same dates: the US moves in mid-March and early November, Europe in late March and late October. In the fortnight or so between, the usual difference is out by an hour.
Those two windows in March and October are when a recurring call quietly moves for one side and not the other.
PST and GMT
- Same all year
- No, one hour less for part of the year
- Shared office hours
- None between 9 and 5
Booking a call between Los Angeles and London (winter)
There is no overlap in a nine-to-five day. At 8 hours apart, one side is always outside working hours while the other is in them. Somebody takes an early morning or a late evening. The useful thing is to decide which, once, rather than rediscovering it every week.
When it is 9:00am in Los Angeles it is 5:00pm in London (winter). When London (winter) opens at 9:00am, Los Angeles reads 1:00am.
PST covers the US west coast and British Columbia: Los Angeles, San Francisco, Seattle, Vancouver, San Diego. GMT covers the UK in winter, and much of west Africa all year: London (winter), Dublin (winter), Accra, Reykjavik.
PST to GMT: common questions
What time is it in GMT when it is 9am PST?
5:00pm. GMT is 8 hours ahead of PST. The table above runs the same conversion for every hour of the day.
Why is my PST to GMT conversion off by an hour?
Because of daylight saving. The gap is stable for most of the year and wrong for about three weeks of it. The United States and Europe both use daylight saving, and they do not start and finish it on the same dates: the US moves in mid-March and early November, Europe in late March and late October. In the fortnight or so between, the usual difference is out by an hour. If a conversion looks an hour out, check which side of a clock change the date falls on.
Why does PST to GMT show tomorrow’s date?
Because the gap is large enough to cross midnight. GMT is 8 hours ahead of PST, so an evening in PST is already the next morning in GMT. It is not an error; the date genuinely differs while both clocks are running normally.
When can PST and GMT actually meet?
There is no overlap in a nine-to-five day: the difference is 8 hours ahead, which puts one side outside working hours whenever the other is in them. Somebody has to take an early morning or a late evening, so it is worth deciding which end that is rather than rediscovering it every week.
