What time does 4:00 am convert to in military time?

In military time, time is expressed in a 24-hour format rather than the typical 12-hour format used in civilian timekeeping. The conversion from civilian time to military time involves eliminating the colon and representing the hours without the "AM" or "PM" suffix.

For the specific case of 4:00 AM, it is represented as 0400 in military time. The first two digits represent the hour (04 for 4 AM), and the last two digits represent the minutes (00 for the top of the hour).

Therefore, when converting 4:00 AM to military time, you simply write it as 0400, clearly indicating the time in the early morning hours. This method of expressing time ensures clarity and uniformity in communication, especially in military and nautical contexts.
