What is the military time representation for 11:00 PM?

In military time, the hours are represented on a 24-hour clock format, where the day begins at midnight (0000) and continues through to 2359, just before the next midnight. To convert standard time to military time for hours that fall in the PM, you add 12 to the hour, up until 11 PM.

For 11:00 PM, you start with 11 and add 12, resulting in 23. Therefore, 11:00 PM in military time is represented as 2300. This format is used to avoid confusion between AM and PM, which is particularly crucial in military operations where precise timing is essential.

The other options do not correctly represent the time of 11:00 PM because 2100 refers to 9:00 PM, 2400 represents midnight of the following day (which is often used interchangeably with 0000), and 2200 corresponds to 10:00 PM. Thus, 2300 is the accurate military time for 11:00 PM.
