Universal Time (UT) is an international time standard that is used as a basis for all other time zones around the world. It is based on the mean solar time at the Prime Meridian, which is located at 0° longitude. Universal Time is also known as Greenwich Mean Time (GMT) and is the same as Coordinated Universal Time (UTC). It is used to measure the passing of days, hours, and minutes and is essential for the accurate calculation of the position of celestial bodies and navigation. Universal Time is used in a variety of applications such as meteorology, astronomy, navigation, and other scientific endeavors.
