This offset is the number of seconds difference between that timezone and UTC.įor the example in this article, the offset between UTC and CST is -21600 and the offset between UTC and EST is -18000.īelow are some examples of the number of hours difference between various timezones and UTC: United States UTC is the new and improved version of Greenwich Mean Time (GMT).Īll of the different timezones will have an offset assigned to them. Notice that I didn't say there are exactly 24, because actually some locations have a 1/2 hour shift in their times, and are not one of the strict 24 hour divisions.Īnyway, a standard time within most of those timezones is a certain offset (a number of hours) from UTC, which is the abbreviated name for Coordinated Universal Time. There are around 24 different time zones that the world is divided into. It can get really confusing, which is why we built this very simple tool that is designed to help anybody quickly and easily convert a time like 7:38am from CST to EST without having to think too much about it. Not only that, but some locations in the same time zone actually have different offsets. If you've ever set your clock forward or back by one hour, you know that daylight savings time can also change how many hours difference there is between two timezones. If you have ever worked with timezones before, you may know that while they seem to be technically easy, there are lots of things to consider and it can sometimes get complicated when you try to calculate a time conversion like 7:38am CST to EST. In this example, CST is 1 hour ahead of EST, which means that in order to convert 7:38am from CST to EST, we deduct 1 hour from 7:38am to give us the answer, 8:38am EST. Are you looking to convert 7:38am from CST to EST? In this article, we'll give you the answer, but also explain how to calculate the difference in these two timezones.
