Convert 24-hour military time to standard AM/PM time, or the other way around.
To convert military time to standard time, subtract 12 from any hour of 13 or more and add PM. 1730 is 5:30 PM, 2100 is 9:00 PM, and 0000 is midnight (12:00 AM). Hours 01 to 11 are AM and 12 is noon.
From military to standard: if the hour is 13 or more, subtract 12 and add PM. 1730 becomes 17 − 12 = 5:30 PM. Hours 01 to 11 are AM, 12 is noon (PM), and 00 is the midnight hour (12 AM).
From standard to military: for PM times from 1:00 to 11:59, add 12 to the hour. 3:15 PM becomes 1515. For 12 AM times, use 00 (12:40 AM is 0040). Morning times only need a leading zero (7:05 AM is 0705).

Hospitals, emergency services and many shift-based employers use 24-hour time to avoid AM/PM mistakes on overnight shifts. To work out a shift's length, subtract the start from the end. If the end is smaller, add 24 hours first: 1900 to 0730 is (7.5 + 24) − 19 = 12.5 hours. The time card calculator handles overnight shifts automatically.
