What does 2200 mean in military time

Military time, also known as 24-hour time, is a way to measure the passage of time that is used around the world by both civilians and military personnel. In this system, instead of using AM/PM as a way to denote morning and afternoon times as we do in the Western world, time is expressed as a four-digit number between 0000 and 2359. Each hour of the day is represented with two digits from 00(midnight) to 23 (11 PM).

When expressing military time, the hours between 00 and 12 are prefaced with a zero for clarity. So 2200 would read as "twenty-two hundred hours" or "10 PM". The 00 at the end of this number indicates that it is exactly 10 o'clock, rather than any other minute past 10. This system is useful for those working in aviation and other industries where exact timing can be critical due to arriving at the correct destination on time or scheduling meetings accurately.

Military personnel are required to use this method when completing reports or keeping records due to its relative accuracy and ease of use. In some cases it could be important for civilian personnel as well since military installations may not allow visitors onto their grounds until a certain hour - denoted in military time - has been reached. For example, one may see signs that state "No entry before 1600 (4PM)" outside of an installation's gate.

Military time can also be used when noting the start and end times of meetings — especially during night shifts. Since AM/PM can sometimes be confusing after long hours have been worked, using four digits to denote an exact time makes it easier for both military personnel and civilians alike to understand when they are being called upon or dismissed from their duties respectively. Additionally, military members may use this form when communicating with international partners to ensure that certain events occur concurrently as times zones differ around the globe.
