What is Military time?

There are two systems of keeping time in this globe, the 12- hour and the 24-hour. The 24- hour organization is reserved for keeping hours in military. Countries like United States, United Kingdom, Malaysia, Philippines, Jakarta, New Zealand, Australia and India use the 24-hour time structure or Military Time Format for the military and other emergency services. These countries have the 12-hour clock system to keep time for the civilians.

24 hours time

In the 12-hour clock arrangement, the day is divided into two – 12 hours from midnight to noon (anti meridian – AM) and 12 hours from noon to midnight again ( post meridian – PM). The military time is based on a 24-hour clock system. In this arrangement, the day runs from zero to 23 hours, i.e. midnight to midnight. Here midnight refers to 00:00 and the last minute of the day as 23:59. Sometimes midnight is also specified as 24:00 and it marks the end of the day (refer military time chart given below). For example, you would say that Wednesday ends at 24:00 tonight and Thursday begins at 00:00.

How to Read Military Time

Regular time (or the 12 hour clock) uses a.m. and p.m. to identify the time of the day. In military time, a unique two-digit number identifies the hours and minutes, which is why there is no need to use a.m./p.m.

With hypersensitive issues like military, the use of the 12 hour clock system can be quite cumbersome and dangerous. This can be quite confusing in a case like whether a time given is 12 in the midnight or in the noon.

Comparatively, in the 24- hour system of keeping time or by using the military time chart calculating duration is quite easy. Military time or astronomical time is divided into 24- hour increments and forms the international standard of time telling due to the rarity of its use.

How to convert military time to civilian time?

Once you get a hang of the basics of military way of keeping time, converting it to the civilian way becomes quite easy. Here’s how to do it: The hours from 1 am in the night to the noon is same as civilian clock. The hours below 10 are denoted by adding a zero in front of them, such as, 8:00 am becomes 0800.

History of Military Time

The history of armed forces time can be dated back to the Early Egyptians in the 11th Dynasty. The opening night of a 24-hour clock was located on a coffin lid which is notoriously referred to as the Diagonal Star Table.

The Egyptians integrated the time system with certain patterns of constellations that travelled through the sky during the night. This system was defined by the various quantities of light strength that was present throughout the day and also season. The constellation patterns would eventually become a year with 360 days.

As world wars progressed, there were significant improvements from every nation in technique and also interaction. Among these enhancements being the adaptation of the 24 hour clock because the 12 hour clock posed excessive room for error. The United States Navy adopted the 24-hour system in 1920 and later on by the Army in 1942 and also till today Navy Seals established their watches to army time.
