What is Military Time?

Military time is a system of timekeeping that uses the 24-hour clock instead of the traditional 12-hour clock used in standard or regular time. It is especially important in the military, law enforcement, and medical fields for accurate communication and coordination between personnel. While it is not widely used outside of these organizations in the United States, understanding military time can be useful for converting between different time zones or for easier scheduling when communicating internationally.
