Military Time Converter

Convert between military time and standard 12-hour time. Type a time in either box and get the match right away, plus a full 24-hour chart for quick lookups.

Stop Doing the Math in Your Head

Adding or subtracting 12 in your head is where most military time mistakes happen, especially with hours right around noon. Type the time you already have and let the converter handle the rest.

0000 – 2359

Why Use This Converter?

Works Both Ways

Start from either format. Type a 12-hour time or a military time and the other box fills in automatically.

Full 24-Hour Chart

Every hour of the day is listed below, so you can look up a specific time like 1930 without typing it in.

Live Clock Included

See your device's current time in both formats at the top of the page, updated every minute.

No Invalid Times

Hour and minute values are kept within range automatically, so you can't end up with something like 25:70.

How this Military Time Converter works

Military time removes the AM/PM split by numbering every hour from 00 to 23, so 1:00 PM becomes 13:00 and 11:45 PM becomes 23:45. Type a time into either box on this page and the other one fills in as you go, so there's no need to add or subtract 12 in your head. Midnight is the one time that trips people up: it is written as 0000, not 2400, because 2400 marks the very last moment of the day, one second before the clock resets to a new one. The chart below the converter lists all 24 hours side by side, so you can look up a specific hour, like what 1830 or 0915 means, without typing anything. A live clock above the converter also shows your device's current time in both formats, refreshed every minute.

Frequently Asked Questions

What is military time?
It is the 24-hour clock format used by the military, hospitals, and pilots. Instead of restarting the count at 1 after noon, the hours just keep going: 1 PM is 13:00, 6 PM is 18:00, and so on up to 23:00 for 11 PM.
Why is midnight written as 0000 and not 2400?
0000 marks the start of a new day, while 2400 would mean the very last moment of the day that just ended. Most systems use 0000 for the start of a day and reserve 2400 only for marking an exact end time, like a shift that runs until midnight.
How do I convert 12-hour time to military time by hand?
For any time after 12 PM, add 12 to the hour and drop the AM/PM label. So 4:30 PM becomes 16:30. For times before noon, keep the hour the same and just add a leading zero if needed, so 8:05 AM becomes 08:05.
What does "hours" mean after a number like 1400 hours?
It is just how military time is read aloud. "1400 hours" means 2:00 PM. The word "hours" is added after the number instead of saying "o'clock," and each digit is often spoken separately, like "fourteen hundred."
Is military time the same thing as 24-hour time?
Yes, they are the same format. "24-hour time" is the general name used in most of the world, including on digital clocks, transport schedules, and computer systems. "Military time" is simply the term used more often in the US and Canada for that same format.
What is noon in military time?
Noon is 1200. There is no AM or PM confusion at this point since the format only counts up from 0000 to 2359, so 1200 always means the middle of the day and never midnight.
How do I read a time like 1830 out loud?
1830 is read as "eighteen thirty" or "six thirty PM." Split the number into hours and minutes: 18 is the hour (6 PM) and 30 is the minutes past that hour.
Does military time change based on time zone?
No, military time is only a way of writing the hour and minute, not a time zone. A time like 09:00 could be morning in one city and evening in another, depending on which zone the clock is set to.
Why do flights, trains, and hospital charts use military time?
It removes the AM/PM mix-up that causes real scheduling mistakes, like showing up 12 hours early or late. Since every hour from 0 to 23 has its own number, there is no way to confuse morning and evening on a printed schedule.
