How to Read Military Time
When keeping hours in this fashion, the day starts at midnight and is written as 00:00. The last minute of the day is written as 23:59, or one minute before the next midnight. Sometimes you may see 00:00 written as 24:00. Both are acceptable.
A usage example showing the 12 hour clock vs military time would be a time table showing 4:00 pm to 12:00 midnight. This would be written as 16:00 – 24:00. Another example highlighting the difference between the two would be to show that 10:15 am is written as 10:15 in military time but 2:30 pm is written as 14:30.
There are only two things to remember to help you tell military time:
The morning hours are the same. So 1:00 a.m. is the same in both military and civilian time. This holds true all the way up to 12:59 p.m.
For everything after 12:59 p.m., just add 12 to the hours. For example, 2:00 p.m. becomes 14:00 (12+2=14), and 10:00 p.m. becomes 22:00 (10+12=22).
This method of keeping time is most commonly used by the military, government, public transportation, hospitals, meteorologists, astronomers, those employed in emergency services, and also with computers. When speaking in military time, 07:00 may be stated as “zero seven hundred” or “oh seven hundred”. Also, in the military, these time stamps are often written without the colon, so 07:52 would rather be written 0752.
Time stamps referencing Greenwich Mean Time (GMT for short – often interchanged with Coordinated Universal Time/UTC) is denoted by a “Z” at the end, and is written as 0752Z. The local time is denoted by a “J” at the end, and the eastern time zone is denoted by an “R” at the end. Each of the zones have a corresponding letter and name.
