The 24-hour clock, popularly referred to in the United States and some other countries as military time, is the convention of timekeeping in which the day runs from midnight to midnight and is divided into 24 hours. This is indicated by the hours passed since midnight, from 0 to 23.

How do you explain 24 hour time?

In the 24-hour clock format, each day runs from midnight to midnight and is divided into 24 hours. 24-Hour Clock Time uses the numbers 00:00 (midnight) until 23:59 to tell the time. You don't need to use am / pm with a 24-Hour Clock, as afternoon is indicated by a number bigger than 12.

Is it midnight 0000 or 2400?

The question sometimes arises whether midnight is written as 2400 or 0000. Military and emergency services personnel refer to midnight both ways. However, digital watches and clocks that display time in a 24-hour format and computer equipment treat midnight as the start of a new day and express it as 0000.
