The U.S. Navy began using military time in 1920, followed by the U.S. Army in 1942. Today, military time is extensively used in aviation, navigation, emergency services, and the military itself.
Understanding Military Time
The military time system starts at midnight, which is represented as 0000 hours. The day progresses chronologically, with each hour assigned a unique number from 0100 to 2300 hours. After noon (1200 hours), military time continues chronologically, adding 12 hours to the standard time. For example, 1:00 PM is represented as 1300 hours, and 5:00 PM is represented as 1700 hours.
Converting Between Military and Standard Time
Converting between military and standard time is relatively straightforward. To convert military time to standard time, subtract 12 hours from the military time if it is greater than 1200 hours. For example, 1700 hours would be 5:00 PM in standard time. If the military time is less than 1200 hours, simply add 12 hours to obtain the standard time. For instance, 0300 hours would be 3:00 AM in standard time.
To convert standard time to military time, add 12 hours to the standard time if it is afternoon or evening (i.e., between 12:00 PM and 11:59 PM). For example, 5:00 PM would be 1700 hours in military time. If the standard time is between midnight and 11:59 AM, simply remove the AM/PM designation and add a zero in front of the hour if it is less than 10. For instance, 9:00 AM would be 0900 hours in military time.
Pronunciation of Military Time
When pronouncing military time, leading zeros are said out loud, and “thousands” are not used. For example, 2000 military time is pronounced as “twenty hundred” or “twenty zero zero”. This pronunciation helps to avoid confusion and ensure clarity in communication.
Conclusion
Military time is a precise and efficient timekeeping system used by the military and various professions worldwide. Its 24-hour format eliminates ambiguity and aligns with international standards. Understanding military time is crucial for effective communication and coordination in various fields, including aviation, navigation, emergency services, and the military itself.
