Military time chart
Military time runs from midnight to midnight without AM and PM. Midnight is 0000, noon is 1200.
- Morning, 1:00 AM to 11:59 AM: the hour stays the same, written as four digits. 3:00 AM is 0300.
- Afternoon and evening, 1:00 PM to 11:59 PM: add 12 to the hour. 4:00 PM is 1600.
- Midnight and noon: midnight is 0000, and the hour after it is 0015 or 0100, not 1215 or 1300. Noon is 1200.
- Going the other way, subtract 12 from any hour above 1200 to get the PM time.
Frequently asked questions.
What is military time?

Is midnight 0000 or 2400?
Both are in use. 0000 marks the start of a day, 2400 the end of one. In practice 0000 is the more common of the two.
Why do some people call it the 24-hour clock instead?
Outside the United States it is simply how time is written. In the UK, Europe and most of the world the 24-hour clock is standard on timetables, rosters and software, and the term “military time” is rarely used.
