Military time is similar to civilian time during the morning hours (Midnight to Noon). After Noon, military time continues to increment the hour digit, whereas civilian time starts over.
To convert military time after Noon to civilian time, subtract 12. For example, 1800 hours becomes 6:00pm.
To convert civilian time after Noon to military time, add 12. For example, 5:00pm becomes 1700 hours.
Military time is also pronounced differently than civilian time. 9:00am in civilian time is 0900 in military time, and it is pronounced oh-nine-hundred. A military person would refer to 7:00pm civilian time as nineteen hundred hours in military time.
