How to say 2100 in military time

The 24-hour clock or "Military Time" uses a unique system for telling time that can be slightly confusing to those unfamiliar with it. In military time, the day begins at midnight, which is 0000 hours. For example, 1:00 AM would be 0100 hours while 1:00 PM would be 1300 hours. This format continues throughout the day by adding or subtracting 1200 hours after noon. Knowing how to use and convert between military time and standard time is essential in many industries, such as aviation and the military.

So, how do you say 2100 in military time? 2100 hours is equivalent to 9:00 PM in standard (or "civilian") time. To show this same time on a 24-hour clock, all you have to do is add 1200 hours (or one "click" of the clock). Therefore, 2100 in military time represents 21 + 12 = 33 or 9:00 PM on a 12-hour clock.

There are several other examples that may help you better understand how to read and convert between the two different formats. 5PM in civilian or standard time can easily be converted to 1700 on a 24-hour clock; 15 minutes past noon (12:15) would be 1215 hours; and 8AM translates to 0800 on a 24-hour scale.

It's important to recognize that AM/PM distinctions are not made in military time as every hour has 2400 minutes (100 minutes per hour). This means that 2100 could refer to either 9PM at night or 9AM in the morning but context should make it clear which one is being referred to. For instance, if someone were referring to their bedtime as "2100" then it would almost certainly be referring to 9PM since most people don't go to bed so early in the morning!
