What is Military Time? ⏰
Military time is a method of keeping time that uses a 24-hour format instead of the 12-hour format most people are accustomed to. It eliminates the ambiguity of AM and PM designations. This system is widely used in military contexts, transportation (like airlines and trains), and in various global settings where clarity is crucial.
The Basics of Military Time
In military time, the day runs from 00:00 (midnight) to 23:59 (one minute before the next midnight). Each hour of the day is represented by a two-digit number. Here's a quick breakdown:
- Midnight to Noon:
- 00:00 to 11:59
- Noon to Midnight:
- 12:00 to 23:59
Converting Military Time to Standard Time
To convert military time into standard time (12-hour format), follow these simple rules:
- From 00:00 to 12:59: The military time is the same as standard time (with the exception of midnight which is 12:00 AM).
- From 13:00 to 23:59: Subtract 12 from the military hour to convert to standard time, and add "PM".
For instance:
- 17:00 (military) = 17 - 12 = 5:00 PM (standard)
- 08:30 (military) = 8:30 AM (standard)
Breaking Down 17:21 Military Time
Now let's focus on our example: 17:21.
Step 1: Identify the Hour
