How to Quickly Convert From Military Time

Military times are written with four digits (e.g., 0100 which is 1:00 AM). The first two digits are the hours and the last two digits are the minutes. If a time only has three digits, then the first one is the hour (e.g., 100) and the last two digits are the minutes.

The easiest way to convert a time from military time is to subtract 12 from any hour that is greater than 12 and add PM to the end. For example, if you see 1300 as the time, the hours are 13 and the minutes are 00. Since 13 is greater than 12, subtract 12 which gives you 1 (13-12=1) so you have 1:00 PM.

It is helpful to know that all military bases, including those overseas, observe the standard United States calendar with 12 AM and 12 PM occurring 59 minutes apart. They also use 24-hour days just like we do but they use two digits per hour. For example, if it’s a Monday at 10:30 AM, it would be 10 30. If it’s 1:30 PM on Friday, it would be 13 30 (1/13).

How to Quickly Convert to Military Time

If you are trying to convert to or from military time, there is a simple formula that you can use based on what type of time it is:

If it’s AM/PM, then it’s the same as normal. For example, 10 30 would be 8 o’clock in the morning. If you need more precision than in 30-minute intervals, then add one digit for each additional 15 minutes. For example, 12:15 would be 12 1/4 (12 and 1/4th).

Once you’ve figured out what time it is in military time, if you need to convert back to regular 24-hour clock time, then just subtract 12 or simply add 12 hours. For example, it would be 04 30 if it’s 2:30 PM.

If you are working on a base that uses military time, this part is easy because it’s just another measurement system; however, if you are working with someone who has to convert to or from military time for work, then they have to learn what AM/PM means and how each hour is broken down into ten 30-minute intervals. This takes time and practice.

What Is Military Time?

While most people in the military use a 24-hour clock, civilians usually have to know whether a specific time is AM or PM. The 24-hour clock makes knowing the exact time efficient. If someone told you to meet at “five-o-clock” you might ask if that is in the morning or evening. With military time, they would have told you “Zero Five Hundred Hours” or “Seventeen Hundred Hours” which would clear up the confusion.

Military time is a term that specifically refers to the way time is measured in the U.S., and it’s typically used by people working on military bases, such as ones overseas.

While this type of measurement may be different, it’s really not all that complicated when you know what each number stands for and how they are applied. What is military time?
As a general rule, military time is a system of telling when it is. It’s also used to report the times of briefings, meetings, and calls. Unlike standard time, the military time has the hours using numbers from 0-23 instead of 1-12. There are also distinct letters for the minutes of the hour.

The History of Military Time

Military time is a relatively recent concept. While most people can easily work with it, it’s going to take a little bit of time to get used to it.

In 1896, the U.S. Naval Observatory was established, and in keeping with its role as a government agency for astronomical research, its first duty was to establish a standard time that was uniform around the country and internationally. The need for this came on the heels of two major events in American history: the Mexican-American War and the Civil War. For those unfamiliar with these terms, both were conflicts where at least one side tried to end slavery. While they ended differently, they did bring forward issues regarding how slavery should be handled in the U.S.

The Mexican-American War, which was fought from 1846 to 1848, primarily over California and other territories. The war didn’t end the slave trade in the U.S., but it did bring about a move for Congress to abolish slavery altogether. The Civil War, which took place from 1861-1865, was fought over issues of states’ rights versus federal powers as well as the abolition of slavery.

The issue of time in this scenario is important because while it may not have been a major factor during the Civil War, it was certainly an issue that came up after the war ended. In fact, it was even something that was discussed during the Mexican-American War, which is considered the first of the “modern wars”. At this time, when the U.S. Navy began setting up its Military Timekeeping Service, it was originally designed for military purposes only. This included keeping track of military bases and planning operations around the world.

In 1913, President Woodrow Wilson issued an executive order to establish standard time zones in every state of America as well as those in Canada and Mexico simultaneously across all three countries. With this came an international system of time zones known as Universal Coordinated Time (UTC) or Greenwich Mean Time (GMT). It is important to know the history of military time because it is based on the same system as the universal time zones.
