US: Nebraska, Wisconsin, Alabama, Arkansas, Louisiana, Texas, Illinois to mention a few. Mexico: México (including Mexico City), Oaxaca, Yucatán, San Luis Potosi, Chiapas and more.Ĭanada: Saskatchewan (only Creighton and Denare Beach), Manitoba and most ports of Ontario Example of states observing Central Standard Time: With the exception of the North West corner, all of Mexico observes CST. Similarly, only Canadian provinces in the middle of the country observe CST. 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. 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! Countries observing CST:ĬST 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 summer CST becomes CDT – Central Daylight Time. It is six hours behind UTC and is observed during the winter months. Not even Ireland are on BST in the summer, instead they have their own time zone for this.Ĭentral Standard Time is the time zone of the central US and Canada, as well as Mexico and most of Central America. While GMT is observed in many places in addition to the UK BST is only observed in Britain (as the name suggests). 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. Summer time and Daylight saving time:īST is the summer time equivalent of GMT. United Kingdom only, including the Isle Of Man Example of cities observing it:Īll cities in the United Kingdom (England, Scotland, Wales and Northern Ireland), such as London, Manchester, Edinburgh, Cardiff and so on.
