Est time zone to gmt4/12/2024 Obviously, they couldn’t calculate the exact time but it was enough to plan their day and make predictions about the following events. Specifically, when the sun was the highest in the sky, they could tell that it was noon. Consequently, the majority of people were well-aware of nature and its wonders. Both ancient people and those from the 18th century used to observe the sun every day in order to find out what time of the day it was. Most western countries can’t imagine measuring the time without nowadays’ standards but did you know that EST was founded only several centuries ago?įor millions of years, people measured time by using natural resources such as the sun or moon. In other words, while most countries around the world observe time zones correlating to their geographical realities, sometimes time zone decisions can be purely political – or, in the case of France with numerous territories around the world, simply bizarre because of historical reasons. The offset is usually one or more whole hours, but there are countries with offsets of 30 minutes (India, for example) and even 45 minutes (Nepal, for example).Īnd while there are many countries that are split between time zones (Russia spans over 12 of them), there are also countries that only observe one time zone despite spanning vast territories (China, for example). In the case of the Eastern Standard Time zone, the time is 5 hours behind UTC time. This difference from UTC time is the UTC offset. Anything that is West from the zero longitude will have a minus offset, and anything that is East will have a plus offset.ĮST, the Eastern Standard Time observed in the Americas, as an example, is UTC-05:00, while the time observed in Central Asia will be UTC+05:00. It may sound confusing, but think of it this way: while both stand for the exact time at the zero longitude, UTC is the standard, and GMT is the time zone.Īll time zones around the world are UTC plus or minus some time (usually one or more hours). It is the standard when it comes to measuring time around the world originating from the GMT, or the Greenwich Mean Time, which used to be the only time standard measured at the Greenwich Meridian (0 longitude), UTC now defines the „zero hour“ time standard and is commonly mistaken for GMT which is a time zone rather than a time standard. UTC stands for Coordinated Universal Time. And if you’re after some fun time zone facts, make sure to read the entire page – we’ve listed some weird and wonderful time zone facts at the bottom of the post. It gets even more confusing knowing that the North and the South Poles have no time zones at all, and astronauts follow the GMT regardless of where they are… So let’s start at the beginning and explain what time zones are, what UTC is, and what it is used for, and then analyze the EST time zone which covers several countries and major cities in the Americas. In fact, most people erroneously believe they are in the UTC time zone when they are really in the GMT time zone. However, most people don’t know exactly what a time zone is, and they may not know what UTC is, either. To make things simple, all time zones are defined by the Coordinated Universal Time ( UTC), which is a time standard. So what are time zones, how are they set, and how is time calculated around the world? Because of this fact, time zones usually follow the boundaries of countries or regions (although there are curious exceptions to this). Truth be told, it is very helpful for countries and people who do business together and who conduct all sorts of other activities together to keep the same time. To keep track of time around the planet, countries adhere to certain time zones. Time zones were set to determine noon around the world because of the Earth’s rotation, noon comes at different times in different places around the world. Sounds crazy, right? However, time zones have been created for a wide variety of social, legal, and commercial reasons. By contrast, if you’re flying to Tokyo or Vladivostok, you’re catching up with tomorrow, as Japan and Russia are eleven time zones ahead of Europe. It’s weird to think that you can, quite literally, travel in time: if you’re leaving Paris or London and heading to Phoenix or San Francisco, you’ll arrive earlier than you’ve left. If you have ever traveled internationally, you’re probably familiar with the confusing effects of jetlag and the adaptation to a different time in another country.
