In the graph below you see the time zone difference between Eastern Standard Time and British Summer Time. Drag the bubble to adjust the time and to see the corresponding time in the other time zone.
Eastern Standard Time is the time zone of the Canadian and US East Coast, including cities like Montreal, Ottawa, New York, Washington D.C. And Miami. 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 before lunch for the person in EST and in the afternoon for the person in BST.
This is the standard time of the Eastern US, Canada and parts of the Caribbean. It is in most places observed only in the winter months, from November to March. The origin of EST is the same as for most time zones – it was introduced when the railroad was built across the United States. It is important to note that there is also Eastern Standard Time in Australia, but this is usually called AEST and thus not to be confused with EST.
Most of the Eastern seaboard of the US observe EST, as well as most locations in Eastern Canada although there are a few exceptions. Locations such as New York, Washington, Quebec and Ontario are all on Eastern Standard Time. Also some Caribbean locations such as Jamaica, Haiti and Panama are in this time zone.
It is important to note that with the exception of Panama, Jamaica and a couple of locations in Canada and the US most in this time zone do observe DST and thus switch to EDT in the summer. As always, it is better to look up the actual location than the timezone itself.
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.
