In the graph below you see the time zone difference between Central European Time and British Summer Time. Drag the bubble to adjust the time and to see the corresponding time in the other time zone.
Central European Time is the time zone of most central European countries, and the Nordics, including cities like Paris, Berlin, Stockholm, Amsterdam, Madrid, Rome, Zurich and Warsaw. British Summer Time is the time zone of the United Kingdom when observing daylight saving time in the summer, with places like London, Dublin and Glasgow.
Usually it is preferable to schedule meetings any time from the morning for the person in CET and any time from the morning for the person in BST.
CET is, as the name implies, the time zone for Central Europe. Important to note is that in summer Central European Time becomes CEST, which stands for Central European Summer Time. In practice, “Central” means “Western” as Central European Time includes everything from the Nordics to Spain. Note that Portugal and the UK are not on CET but instead observe GMT and that Eastern Europe (every country from Finland and South) observe Eastern European Time.
All countries in Western Europe, except Portugal and the UK, observe Central European Time. This includes Germany, Sweden, Italy, Spain, Croatia, Montenegro and Gibraltar to name a few.
The list is long but includes Berlin, Oslo, Madrid, Rome, Tirana, Amsterdam, Paris, Warsaw, Bern, Geneva and Copenhagen.
Daylight Saving Time is applied in Central Europe/Western Europe. CET in that case becomes CEST – Central European Summer Time and is one hour different. CEST is observed between the last Sunday of March and the last Sunday of October.
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.
