Military time, also known as 24-hour time, is a method of telling time where the day runs from midnight to midnight, divided into 24 hours. Instead of using the conventional AM and PM system, military time avoids confusion by counting from 00:00 (midnight) to 23:59 (11:59 PM). That way, each time of the day is unique.
For example, in regular 12-hour time, you might need to clarify whether a time like 7:00 refers to morning (AM) or evening (PM). In military time, 0700 is 7 AM and 1900 is 7 PM. This clarity helps ensure there are no misunderstandings, which is especially important in certain jobs and fields.
How is Military Time Written?
Writing military time is simple but requires some getting used to if you’re accustomed to the 12-hour clock. Here’s a step-by-step guide to writing it:
First 12 Hours (Midnight to Noon):
- These hours are similar to regular time but without the colon or AM/PM.
- Midnight is written as 0000 (pronounced “zero hundred hours”).
- 1:00 AM is 0100 (pronounced “zero one hundred hours”).
- 11:00 AM is 1100 (pronounced “eleven hundred hours”).
Second 12 hours (Noon to Midnight):
- For times after noon, simply add 12 to the hour.
- 1:00 PM is 1300 (pronounced “thirteen hundred hours”).
- 9:00 PM is 2100 (pronounced “twenty-one hundred hours”).
- 11:59 PM is 2359 (pronounced “twenty-three fifty-nine hours”).
In this format, there’s no need for a colon between the hours and minutes, and it’s always clear whether it’s day or night.
Why Use Military Time?
Military time is primarily used by the armed forces, but it’s also common in other fields like aviation, emergency services, and hospitals. Why?
Clarity and Precision:
- There’s no ambiguity with military time. You know right away that 1400 means 2 PM, not 2 AM, and vice versa.
Worldwide Consistency:
- Military time is used around the world, which makes international coordination smoother. It eliminates any confusion due to time zones.
Ease in Electronic Devices:
- Many digital clocks, scheduling software, and other tools use a 24-hour time format. It prevents errors and misinterpretations, especially in critical operations.
Converting Between Military Time and Regular Time
Converting between Military time and regular 12-hour time is easier than it seems. Here’s how you can do it:
From Military Time to Regular Time:
- If the military time is less than 1200, it’s in the AM. Simply place a colon between the hours and minutes, and add AM to it.
- If the military time is 1300 or more, subtract 12 from the hour number to get the PM time. Add PM to the resulting time.
For example, 0800 is 8:00 AM. 1500 is 3:00 PM because 15 – 12 = 3.
From Regular Time to Military Time:
- For AM times, remove the colon and, if necessary, add a leading zero. For example, 7:30 AM is 0730.
- For PM times, add 12 to the hour. For example, 6:15 PM is 1815 (since 6+12 = 18).
Using these steps, you can switch between the two formats as needed with ease.
