How military time works
Military time runs on a 24-hour clock with no AM or PM. The day starts at 0000 (midnight) and runs to 2359. Morning hours match the regular clock (9:00 AM = 0900); from 1:00 PM onward, add 12 (1:00 PM = 1300, 11:00 PM = 2300). Minutes are unchanged.

Midnight: 0000 or 2400?
Both are used. 0000 marks the start of a day and 2400 the end of the previous one — a shift ending at midnight is written 2400, one starting at midnight is 0000. Timesheets usually standardize on 0000.
