Difference Between GMT and UTCDifference Between GMT and UTC – FAQs

Difference Between GMT and UTC: Greenwich Mean Time and Coordinated Universal Time are often used interchangeably or are confused as one, but GMT is a time zone and UTC is a time standard. Even though UTC and GMT share the same time, there is a basic difference between them.

GMT is a time zone that is officially used in European and African countries. The time zone can be displayed in both 12-hour and 24-hour format, whereas UTC is a time standard that is used as the international timekeeping standard and is not a time zone.

In this article, we will learn about the definitions of GMT and UTC, their examples, and the difference between GMT and UTC.
