How to read military time
Military time uses a 24-hour clock cycle where hours are represented from 00 to 23. It is read as a four-digit number. The first two digits represent the hour, and the last two digits represent the minutes. For example, 0800 is read as 'zero eight hundred hours' (8:00 AM), and 1430 is read as 'fourteen thirty hours' (2:30 PM). There is no AM or PM in military time.
How to convert standard time to military time
To convert AM hours to military time: keep the hour the same (e.g., 6:15 AM is 06:15), except for 12:00 AM (midnight), which becomes 00:00. To convert PM hours: add 12 to the hour (e.g., 4:00 PM becomes 16:00, since 4 + 12 = 16), except for 12:00 PM (noon), which remains 12:00.
Why is military time used?
Military time is used in aviation, emergency services, military, navigation, and medical facilities to eliminate the possibility of AM/PM confusion. For example, scheduling a surgery or flight at 07:00 versus 19:00 prevents critical mistakes that could occur in a 12-hour system.
