Overview of Military Time
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 Standard and Military time is how hours are expressed. (Note: 'Standard' time can also be referred to as 'Civilian' time) Standard 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 ?
Standard 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. ?
Standard 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 standard time = 14:47 military time
8:03 pm standard time = 20:03 military time
10:16 pm standard time = 22:16 military time
5:54 am standard 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.
For more information, see this website: http://en.wikipedia.org/wiki/24-hour_clock
Another Common Question:
My minutes to convert are greater than ":60".
For example: 14:75, 2:83, 8:92. What's that all about ?
Answer:
What looks like minutes, like ":75", is actually the % of an hour that you've worked.
So ":75" means 75% of an hour
which is 45 minutes.
This is used on time sheets to calculate pay and has NOTHING TO DO WITH MILITARY TIME. Don't plug
anything into the calculator at the top of the page.
Here's a chart for you. What's in your Minutes field is equal to the # of minutes shown on the far right.
(For example, ":08" equals 5 minutes worked. And ":75" equals 45 minutes worked.)
:08 = 8% of an hour = 5 minutes
:17 = 17% of an hour = 10 minutes
:25 = 25% of an hour = 15 minutes
:33 = 33% of an hour = 20 minutes
:42 = 42% of an hour = 25 minutes
:50 = 50% of an hour = 30 minutes
:58 = 58% of an hour = 35 minutes
:67 = 67% of an hour = 40 minutes
:75 = 75% of an hour = 45 minutes
:83 = 83% of an hour = 50 minutes
:92 = 92% of an hour = 55 minutes
Technical Explanation: The time reported on a time sheet for a half hour of work is ".5" which is odd. If you turn time in as .30 (implying 30 minutes), that only actually pays you 18 minutes! You need to divide the number of minutes worked by 60 in order to turn in the right amount to pay: (# minutes / 60 = .xx)
For example, if you work 45 minutes,
(45 minutes / 60) = .75 = 75%.
75% of an hour is 45 minutes.
