What is Military Time For?
Military time is a method of telling time that is based on the 24-hour clock, instead of the 12-hour clock used in everyday life. It is often used by members of the armed forces and emergency services such as police or firefighters. Military time is also known as “24-hour time” because all times use four digits, with the first two indicating the hour and the last two indicating minutes.
For example, 1:00 pm would be written as 1300 rather than 12:00 pm. This system makes it easier to understand when using military maps or planning operations since there can be no confusion between morning and afternoon hours. Furthermore, military personnel needs to adjust their sleep patterns while serving, so military time helps keep everyone on schedule. Military time is also used by many airlines that must coordinate flights across multiple time zones. While not as widely used in civilian life, understanding how to read and write military time can come in handy in certain situations.
