This zone includes major cities such as Mexico City with a population of 12 million people. The military uses this time zone and designates it with an "S" which stands for "Sierra." it is used in the following countries: Belize, Canada, Costa Rica, Guatemala, Honduras, Mexico, El Salvador, and the United States. This zone is 6 hours behind Universal Coordinated Time (UTC) and is written as UTC -6:00. Let's examine each time zone in more detail: During DST, both of these time zones are in different slots: Eastern Daylight Time (EDT) and Central Daylight Time (EDT) respectively. Always add one hour to the Central time to convert to the Eastern one.īoth of these locations observe Daylight Saving Time, therefore there is a period of each year from March until November where the clocks are moved forward an hour. If it's 5:00 P.M in the CST zone, then it is 6:00 P.M in the EST zone. The Eastern zone is one hour ahead of the Central zone. When converting between these two zones, it's best to remember that these two time zones are adjacent to one another, meaning they are exactly an hour off from each other. Also, tables are available for easy reference to various conversions as you see fit. In this case we're talking about converting Central Standard Time to Eastern Standard Time.īeyond this convenient tool, we also have live clocks for both of these areas that adjust for factors like Daylight Saving Time. 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. Also some Caribbean locations such as Jamaica, Haiti and Panama are in this time zone. Locations such as New York, Washington, Quebec and Ontario are all on Eastern Standard Time. Most of the Eastern seaboard of the US observe EST, as well as most locations in Eastern Canada although there are a few exceptions. 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. 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 in most places observed only in the winter months, from November to March. This is the standard time of the Eastern US, Canada and parts of the Caribbean. The rest of the year these countries are on CET. Daylight saving time and summer time:ĬEST is the summer time of CET – Central European Time and is observed between the last Sunday of March and the last Sunday of October each year. The list is long but includes Berlin, Oslo, Madrid, Rome, Tirana, Amsterdam, Paris, Warsaw, Bern, Geneva and Copenhagen. Example of cities observing Central European Summer Time: This includes Germany, Sweden, Italy, Spain, Croatia, Montenegro and Gibraltar to name a few. Countries using CEST:Īll countries in Western Europe, except Portugal and the UK, observe Central European Summer Time. Note that Portugal and the UK are not on CEST but instead observe GMT (or, in the summer BST – British Summer Time) and that Eastern Europe (every country from Finland and South) observe Eastern European Summer Time. About CEST – Central European Summer TimeĬEST is, as the name implies, the time zone observed by Central Europe during the summer months.
