What time is represented by the military format 1300?

The military format uses a 24-hour clock system to avoid ambiguity between AM and PM times. In this format, the hours are numbered from 00 to 23. Specifically, 1300 hours indicates 13:00 in the 24-hour format. To convert this to the standard 12-hour format, you subtract 12 from the hour if the hour is greater than 12. Thus, 13 minus 12 equals 1, and since it's in the afternoon (after 12:00 PM), it corresponds to 1:00 PM in the 12-hour clock system. This is why the answer representing 1300 is indeed 1:00 PM.
