As the day is approximately 24 hours long, on the military time clock, the day begins at midnight – 0000 in military time – and ends at 2359. Military time is the convention of timekeeping in which the day is divided into 24 hours. Within this system, the day runs from midnight to midnight, from 0 to 23. Today, it is the most widely used time format in the world. The military divided the world into 24 time zones and utilizes the phonetic alphabet to identify each time zone. For converting military time to standard time, input the military time, excluding a colon. Use the military time converter to quickly convert standard time to military time and vice versa. The 24-hour clock, also known as military time, tells time by dividing the day into 24-hour increments, numbered 0000 to 2400. Military time differs from standard time, which uses numbers 1 through 12 and an a.m./p.m. Military time, with its special notation and syntax, is usually only used in certain contexts. The military is an obvious example, but hospitals and emergency services also use the 24-hour timekeeping system.
