A military time chart is a helpful document used to convert between the standard 12 hour clock in the U.S. and a 24 hour clock. Usually, citizens find the conversion process confusing. But having this chart can make whole process easier. People keep it in their wallet and refer to it as needed.

However, the military time is based on the 24-hour clock. It is a process of keeping time in which a day runs from midnight to midnight. It is further divided into 24-hour increments. Military time is used by astronomers, hospitals, and emergency services.

12-hour system:

In 12-hour system, a day is divided into two-cycle. It is used in countries where English is the main language. Some other countries also embrace it too. It has two equal periods of 12 hours;

  • From midnight 12:00 A.M. (Ante meridiem) to midday 12:00 P.M. (post meridiem).
  • From midday back to midnight and then a 24-hour cycle completes.

In a 12-hour, in each period, the numbering runs from 1 to 12 with twelve representing zero as the start point.

24-hour system:

The 24-hour clock system originated from ancient Egypt. It has been used for many centuries and is still being used today. This system is also referred to as the military time conversion. For a total period of 24 hours, it runs the day from midnight to midnight. The counting system of 24-hour time begins at midnight. It is denoted as 00:00 and runs all the way through to 23:59. Moreover, most people use 24-hour system because it is much easier to read and interpret.

How to write the military time?

Likewise 12-hour clock system, it is also displayed in four digits. But it doesn’t use a colon (:) to separate the hours and the minutes. However, the hours and the minutes are written together. In the military time, the first two digits display the hour and the last two represent the minutes. For example, 10:00 A.M., in military format is written as 1000 and read as ten hundred or ten hundred hours.

The main difference between the military time and the 12-hour clock system is in the afternoon hours. In the 12-hour clock system, the hour after midday is written as 1:00 P.M. while in the military format, you have to continue the count from twelve to thirteen, fourteen, and so on. Therefore, the 1:00 P.M. is written as 1300 in the military format.

How to understand military time?

Here are some steps to understand military time;

  • The military time starts at midnight, written as 0000 and read as zero hundred hours. Likewise 12-hour clock, the military time is represented in four digits. The first two digits indicate the hour and the last two represent the minutes. It runs all the way through to 2359 hours. It then resets at 0000 hours at midnight again.
  • To tell the military time, you just have to make sure that the time has four digits. Before the hour, add zero and remove colon for single digit hours. After reaching the two digit hours remove the colon. For example, if you want to convert 5:00 A.M. into military time then add a zero before 5 and remove the colon like 0500 hours.
  • The main difference between the military time and the 12-hour clock system is in the afternoon hours that we have discussed above.
  • You just have to add the number of hours passed since noon for converting noon hours to military time.
  • In the military time, to read hours with minutes just place the four-digit number as two pairs of numbers with tens and one’s digit.


In conclusion, with a help of military time chart, you can easily tell the military time. Also, military time removes the confusion between the AM and the PM. Due to this reason, public transits, doctors, and the armed forces use the military time.
