How it works
Military time is the 24-hour clock written with four digits and no colon. Hours run from 00 (midnight) to 23 (11 PM), so there is never any confusion between AM and PM. For times from 1300 to 2359, subtract 12 from the hour to get the PM time; for times before noon, the hour is the same as on a 12-hour clock, with 00 becoming 12 AM.
