It is also equivalent to the civil time for Iceland, Liberia, Morocco, Senegal, Ghana, Mali, Mauritania, and several other countries. During the winter months, UTC is the civil time scale for the United Kingdom and Ireland. However, in the most common civil usage, UT refers to a time scale called "Coordinated Universal Time" (abbreviated UTC), which is the basis for the worldwide system of civil time. It is affected by small variations in the rotation of the Earth, and can differ slightly from the civil time on the Greenwich meridian. In astronomical and navigational usage, UT often refers to a specific time called UT1, which is a measure of the rotation angle of the Earth as observed astronomically. For that purpose different designations of Universal Time have been adopted. When a precision of one second or better is needed, it is necessary to be more specific about the exact meaning of UT. Sometimes the character Z is appended to a time to indicate UT, as in 0935Z (Zulu). Times given in UT are almost always given in terms of a 24-hour clock. The two terms are often used loosely to refer to time kept on the Greenwich meridian (longitude zero), five hours ahead of Eastern Standard Time.

Here’s how to translate UTC to your local time zone.The times of various events, particularly astronomical and weather phenomena, are often given in "Universal Time" (abbreviated UT) which is sometimes referred to, now colloquially, as "Greenwich Mean Time" (abbreviated GMT). enables you to select up to four time zones to convert.īottom line: The Earth has about 24 time zones, but when scientists mention a time, it’s almost always Coordinated Universal Time (UTC). For example, the table shows that Eastern Standard Time is three hours ahead of Pacific Standard Time (U.S.). The table is also useful to determine the difference between the time observed in any two zones. For example, 10 March at 02:00 UTC (2:00 a.m.) is the same as March 9 at 9:00 p.m. When converting a zone time to or from UTC, dates must be properly taken into account. In summer, add 2 hours to get 20:00 CEST. To convert 18:00 UTC into your local time, add 1 hour, to get 19:00 CET. Let’s say you’re in Paris, France, which is in Central European Time. During daylight saving (summer) time, you would only subtract 5 hours, so 18:00 UTC would convert to 1:00 p.m CDT. To convert 18:00 UTC (6:00 p.m.) into your local time, subtract 6 hours, to get 12 noon CST. Let’s say you live in Houston, Texas, which is in United States Central Standard Time.

UTC is the successor to Greenwich Mean Time ( GMT), although their exact definitions differ. Standard time within most time zones is a certain whole number of hours offset from Coordinated Universal Time (UTC), maintained by a large number of very precise “ atomic clocks” kept at laboratories around the world, including the U.S. We say about because some states, regions and countries shift their times by 1/2 hour from the strict 24-hour divisions. The world is divided up into about 24 time zones. UTC (0) is the green vertical stripe just to the left of center.
