In the graph below you see the time zone difference between British Summer Time and Central Standard 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. Central Standard Time is the time zone of the central US and Canada, as well as most of Central America, with places like Winnipeg, Chicago, Dallas, Houston, Mexico City, San Jose and Panama City.
Usually it is preferable to schedule meetings in the late afternoon for the person in BST and before lunch for the person in CST.
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.
Central Standard Time is the time zone of the central US and Canada, as well as Mexico and most of Central America. It is six hours behind UTC and is observed during the winter months. In the summer CST becomes CDT – Central Daylight Time. It is important to remember that not all locations in a given state or province necessarily use the time zone – make sure to check the situation for your exact location!
CST is observed in the US, Canada, Mexico and all of Central America (including Belize, Costa Rica, Guatemala, El Salvador, Nicaragua, Panama and Honduras). In the US it is only the states in the central parts that observes CST, from Wisconsin in the West to Tennessee in the East, and from Michigan in the North to Florida in the South. Similarly, only Canadian provinces in the middle of the country observe CST. With the exception of the North West corner, all of Mexico observes CST.
Mexico: México (including Mexico City), Oaxaca, Yucatán, San Luis Potosi, Chiapas and more.
Canada: Saskatchewan (only Creighton and Denare Beach), Manitoba and most ports of Ontario
US: Nebraska, Wisconsin, Alabama, Arkansas, Louisiana, Texas, Illinois to mention a few.
Most locations in Central Standard Time observe summer time between March and November, then calling it CDT – Central Daylight Time. It is always advisable to check the exact location (e.g. using our time zone converter) instead of relying on time zone abbreviations as there are sometimes exceptions, e.g. some states in the US are split between two time zones.
