Convert between 24-hour and 12-hour time
Military or 24-hour time and standard 12-hour AM/PM time are two ways of writing the same clock, and converting between them is a frequent need. This converter switches between military 24-hour time and standard 12-hour AM/PM time.
Why the two formats coexist
The 24-hour clock removes the ambiguity of AM and PM by counting hours from 0 to 23, which is why the military, aviation, medicine and much of the world use it. The 12-hour clock with AM/PM is familiar in everyday use in some countries. Converting between them matters when reading a schedule in one and needing the other, and the conversion has a couple of catches, midnight and noon, that trip people up. The converter handles these correctly so 12-hour and 24-hour times match exactly.
