Military Time Conversion

Overview
Military time is an unambiguous, concise method of expressing time used by the military, emergency services (law enforcement, firefighting, paramedics), hospitals and other entities.

The main difference between regular and military time is how hours are expressed. Regular time uses numbers 1 to 12 to identify each of the 24 hours in a day. In military time, the hours are numbered from 00 to 23. Under this system, midnight is 00, 1 a.m. is 01, 1 p.m. is 13, and so on.

What about Minutes ?
Regular and military time use the same number of minutes per hour and they use minutes in exactly the same way. There is no need to convert minutes when going back and forth between the two time systems.

What about a.m. and p.m. ?
Regular time requires the use of a.m. and p.m. to clearly identify the time of day. Since military time uses a unique two-digit number to identify each of the 24 hours in a day, a.m. and p.m. are not used.

What about Midnight ?
The question sometimes arises whether midnight is written as 24:00 or 00:00. 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 00:00.

Above, we've converted the hours and each 15 minute interval.
But ANY time can be converted to military time.

For example, 2:47 pm regular time = 14:47 military time
8:03 pm regular time = 20:03 military time
10:16 pm regular time = 22:16 military time
5:54 am regular time = 05:54 military time


Common Question: I thought that Military personnel did NOT use colons in military times ?
Answer: True, but Civilians, especially in Science and Engineering, usually DO use commas.
