What is Military Time?
Military time, also known as the 24-hour clock, is used by the military, emergency services, and various organizations globally. Instead of the standard 1 to 12 hours format, military time counts continuously from 00:00 (midnight) to 23:59 (one minute before midnight). This timekeeping method ensures that there is no ambiguity, particularly during operations or emergencies where every second counts.
Military Time Format
Military time is structured as follows:
- From 00:00 to 12:00: It is the same as standard time. For example, 01:00 is 1:00 AM, and 12:00 is noon.
- From 13:00 to 23:59: You subtract 12 from the hour to convert it to standard time. For instance, 14:00 becomes 2:00 PM, and 21:00 becomes 9:00 PM.
Understanding 21:40 in Military Time
