Military Time Card Calculator Online

Military time, also known as 24-hour time, is a timekeeping system that eliminates the need for AM and PM designations. This calculator helps you convert between military time and standard time (12-hour format) with precision.

What is Military Time?

Military time is a 24-hour clock system used primarily by the military and in aviation. It replaces the AM/PM system with a straightforward numerical format where:

00:00 is midnight
12:00 is noon
13:00 is 1:00 PM
23:59 is 11:59 PM

The system eliminates any ambiguity about whether a time is in the morning or evening, making it ideal for scheduling, aviation, and military operations.

Military time is also known as the International Civil Aviation Organization (ICAO) standard time format.
