Coast Guard Practice Exam 2026 – Complete Prep Guide

The time 2400 is not traditionally associated with military time because military time uses a 24-hour clock that rolls over at 0000. When it comes to the end of the day, 2400 represents midnight and is often avoided in practical use, as the next moment is 0000 of the following day.

In military nomenclature, 0000 marks the start of a new day, while 2400 might introduce confusion as it symbolizes the end of a day. In contrast, the times 0000, 1300, and 1159 are all valid representations within the military time system. At 1300, it is simply 1 PM, indicating the early afternoon, and 1159 is one minute before noon, which clearly falls within the accepted military time format. Therefore, 2400 stands out as the time that is not conventionally used in military time.
