What is the UTC time zone?
Coordinated Universal Time, abbreviated as UTC, is the primary time standard by which the world regulates clocks and time. It is related, but not identical to, Greenwich Mean Time (GMT).
The usage of UTC and GMT is based upon a twenty-four hour clock (similar to military time) and is based upon the 0° longitude meridian, referred to as the Greenwich meridian in Greenwich, England.
You will often see time zones represented similar to "UTC - 5" or "GMT - 5". In this example the "-5" refers to that time zone being five hours behind UTC or GMT and so forth for the other time zones. "UTC + 5" or "GMT + 5" would refer to that time zone being five hours ahead of UTC of GMT and so forth for the other time zones.
How do I convert UTC to EST?
EST (Eastern Standard Time) is an important time zone in the United States.
Converting timezones is tricky because of daylight saving times, so it is always safer to use an automated tool such as Time Zone Converter.
The table below explains the conversion from UTC to United States timezones. For example, if it's 2:00 PM in UTC, you need to subtract 5 hours (because EST is UTC-5), so, 2pm UTC is 9am EST.
