Have you ever seen a time written like 19:30 and wondered what it means?
That’s called military time, also known as the 24-hour clock.
Instead of using AM and PM, the day runs from 00:00 (midnight) to 23:59 (11:59 PM).
📜 A Little History
The 24-hour clock has been used for centuries. It became especially important during World War I, when the military needed clear and precise communication.
Using one continuous time system prevented confusion between AM and PM — especially during missions, medical procedures, and transportation schedules.
Today, the 24-hour clock is commonly used in:
• The military
• Hospitals
• Aviation
• Rail systems
• Many countries around the world
🔢 The Easy Trick to Remember It
If the time is 13:00 or higher, subtract 12.
Example:
19:30
19 − 12 = 7
So 19:30 = 7:30 PM
If the number is 12 or lower, it stays the same.
Example:
09:00 = 9:00 AM
11:45 = 11:45 AM
💡 Practical Everyday Example
Let’s say you want to schedule a post for 8:00 PM.
How do you write that in military time?
Since it’s after 12 PM, add 12.
8 + 12 = 20
So 8:00 PM becomes 20:00.
Now you can confidently schedule your post at 20:00 without second-guessing.
🧠 Why It Matters
Military time eliminates confusion.
There is no need to ask, “Is that AM or PM?”
Clear communication builds confidence and real-world skills.
