What Is a Military Time Converter?
A Military Time Converter changes standard 12-hour AM/PM
time into 24-hour time and can also convert 24-hour military
time back into standard time.
The 24-hour clock avoids the need for AM and PM because every
hour of the day has a unique number. This makes it useful
where clear and unambiguous time communication is important.
Example:
5:30 PM in standard time becomes
1730 in military-style notation.
How to Convert Standard Time to Military Time
AM Times
For most AM times, the hour remains the same and is written
with two digits. For example, 7:15 AM becomes 0715.
Midnight is the important exception. 12:00 AM becomes 0000.
PM Times
For PM times from 1:00 PM through 11:59 PM, add 12 to the
hour. For example, 3:30 PM becomes 1530.
Noon is an exception to the add-12 rule. 12:00 PM remains
1200.
Simple Rule:
1:00 PM → 1300
3:00 PM → 1500
8:30 PM → 2030
11:45 PM → 2345
Midnight and Noon in Military Time
Midnight and noon are two times that commonly cause confusion
when converting between 12-hour and 24-hour formats.
Midnight: 12:00 AM = 00:00 = 0000
Noon: 12:00 PM = 12:00 = 1200
After noon, the 24-hour clock continues with 13:00 for
1:00 PM and progresses through 23:59 before returning to
00:00 at the beginning of the next day.
