Military time is a 24-hour timekeeping format commonly used in several fields, such as aviation, military, or healthcare, for which precision counts. Unlike the standard 12-hour clock, military time does not leave room for subjectivity because it continues counting from noon. Thus, 10:00 PM is given as 2200 hours.
It provides absolute clarity in the spoken word, particularly in operational areas where timing becomes significant, and its simple layout provides good applicability for use in digital watches and clocks.
