In the graph below you see the time zone difference between British Summer Time and Pacific Daylight Time. Drag the bubble to adjust the time and to see the corresponding time in the other time zone.
British Summer Time is the time zone of the United Kingdom when observing daylight saving time in the summer, including cities like London, Dublin and Glasgow. Pacific Daylight Time is the time zone of the Canadian and US West Coast when observing daylight saving time in the summer, with places like Seattle, Vancouver, San Francisco and Los Angeles.
Usually it is preferable to schedule meetings in the late afternoon for the person in BST and before lunch for the person in PDT.
British Summer Time, or sometimes called British Standard Time, is the timezone of the United Kingdom in the summer months. It does not have a typical counterpart like most summer/winter pairs but is an exception to adjust for the dark winters in the UK!
United Kingdom only, including the Isle Of Man
All cities in the United Kingdom (England, Scotland, Wales and Northern Ireland), such as London, Manchester, Edinburgh, Cardiff and so on.
BST is the summer time equivalent of GMT. So for half the year the UK is on Greenwich Standard Time and the rest of the year they observe British Summer Time which is one hour ahead.
While GMT is observed in many places in addition to the UK BST is only observed in Britain (as the name suggests). Not even Ireland are on BST in the summer, instead they have their own time zone for this.
Pacific Daylight Time is the time of the Western United States and Canada and is typically abbreviated as PDT. It is 8 hours behind GMT. Although PDT is for the Western part of the US and Canada it is not the Westernmost – both Hawaii and Alaska are on their own time zones due to their location.
Pacific Daylight Time is for the Western US and Canada and thus include locations such as Vancouver, Seattle, San Francisco and Los Angeles. It also extends halfway down Baja California in Mexico. In addition to California and Washington also Nevada and Idaho are on PDT in the summer.
PDT is only used in the summer months so you will need to pay attention to when the switch takes place. Daylight Time is in the Pacific area observed from November to March and is one hour ahead of Pacific Standard Time.
