Military time clock 24 hour professional#
Military Time will be written differently by various organizations and professional groups. However, digital watches and clocks that display time in a 24-hour format and computer equipment treat midnight as the start of a new day and express it as 0000. Military and emergency services personnel refer to midnight both ways. The question sometimes arises whether midnight is written as 2400 or 0000. Converting from decimal hours to hours and minutes is a different issue than converting between regular and military time. Time written in this manner is being expressed in decimal hours (hours and hundredths of hours), not military time. Occasionally encounter time written in a format that appears to use minutes larger than 59 (for example 7:82 or 7.82). One does not need to convert minutes between these two systems because military minutes do not exist. Military Time and Regular Time use the same number of minutes per hour and in the same way. The chart below provides a summary and comparison of Military Time and Regular Time. Military time utilizes a rather special two-digit number to identify each of the twenty-four hours in a day so a.m. It is not necessary to change anything regarding minutes and second when one switches from military time to regular time and vice versa. Minutes and seconds are expressed exactly the same way with military and regular time. Under this system, midnight is 00, 1 a.m. With military time, the hours are numbered from 00 to 23. Regular time uses numbers 1 to 12 to identify each of the 24 hours in a day. The most notable difference between regular and military time is the manner in which hours are expressed. Military time operates on a 24- hour clock that begins at midnight which is referred to as 0000 hours, with 1:00 a.m. Military time is a concise method of expressing time that is used by the military as well as emergency services such as law enforcement, firefighting and emergency medical personnel as well as hospitals. Military refers to this time zone as Zulu Time, and they attach the “Zulu” (Z) suffix, to ensure the time-zone referred to is clear.įor example, a military message or communication might state, “The ship will cross into the area of operations at 1300Z.” That means the ship would arrive in the AOO (Area Of Operations) when it is 1:00 PM in Greenwich, England.Military Time operates on a unique time system. To avoid confusion, in these matters, the military uses the time in Greenwich, England, which is commonly called Greenwich Mean Time (GMT). When it comes to operational matters (such as communications, training exercises, deployments, ship movements aircraft flights, etc.), the military must often coordinate with bases and personnel located in other time zones. When using local military time, the Military observes Daylight Savings Time, if recognized by the state or country that the base is located in.
“The First Sergeant wants to see you at 1600 hours,” means you need to be in the 1SG’s office at 4:00 PM, local time. In other words, “report to first formation at 0700,” would mean you have to be at your first formation at 7:00 AM, local time. Simply at 12 to any PM number (for example, 3pm) and you’ll get the military time equivalent, which in this case would be 3pm + 12 = 15, so 1500 hours is the military time for 3pm! So easy! Military Time in UseĪrmy personnel use local time as a reference.
