THE MILITARY CLOCK SYSTEM. Learn and understand the military 24 hour clock system.

The military clock system uses 24-hour day cycles instead of 12-hour half-days with A.M. and P.M. designations. To convert 12 hour time to 24-hour time, add 12 to 12-hour times from 1 p.m. onwards to midnight.

Examples:

12-hour time Military time
1:00 A.M. 0100
9:00 A.M. 0900 hours
11:30 A.M. 1130 hours
2:00 P.M. 14 hours
7:00 P.M. 1900 hours
10:15 P.M. 2015 hours
One minute after midnight 0001 hours
8 to 5 workday 0800 to 1700
3 P.M Navy time: 6 bells in the afternoon watch
