24-Hour Format Converter
What is the 24-Hour Format?
The 24-hour format, often referred to as military time, is a timekeeping system where the day spans from midnight to midnight, divided into 24 distinct hours. It’s a standard in many parts of the world, especially where precision is critical—like in the military, aviation, and global business.
Many travelers and professionals swear by the 24-hour format for its clarity. Picture this: you’re booking a flight and misread 12:00 PM as midnight instead of noon. It’s a simple mistake that’s happened to countless people, but one the 24-hour format can easily prevent.
Unlike the 12-hour format, which cycles twice daily and uses AM and PM to differentiate morning from afternoon, the 24-hour format assigns a unique number to each hour. For instance, 1:00 PM becomes 13:00, leaving no room for doubt.
This clarity makes it a favorite for written schedules, where mixing up AM and PM could spell disaster.
Understanding the 12-Hour Format
The 12-hour format dominates in places like the United States, Canada, and Australia. It splits the day into two 12-hour chunks: AM (ante meridiem, or “before midday”) and PM (post meridiem, or “after midday”).
It runs from 12:00 AM (midnight) to 11:59 AM, then flips to 12:00 PM (noon) through 11:59 PM. Familiar as it may be, it’s not without its quirks—especially when it comes to pinpointing noon or midnight.

Converting from 12-Hour to 24-Hour Format
Switching from the 12-hour to the 24-hour format is straightforward once you know the steps:
- If it’s AM and not 12:00 AM, keep the hour as is (e.g., 9:00 AM becomes 09:00).
- For 12:00 AM, use 00:00.
- For PM times other than 12:00 PM, add 12 to the hour (e.g., 3:00 PM becomes 15:00).
- If it’s 12:00 PM, it stays 12:00.
Minutes and seconds don’t change—just the hours need adjusting.
Check out these examples:
12-Hour Format | 24-Hour Format |
---|---|
7:30 AM | 07:30 |
12:45 AM | 00:45 |
2:15 PM | 14:15 |
11:59 PM | 23:59 |
Converting from 24-Hour to 12-Hour Format
Going the other way is just as simple—here’s how:
- If the hour is 00, it’s 12:00 AM.
- Hours 01 to 11 stay the same with AM (e.g., 09:00 is 9:00 AM).
- 12 is 12:00 PM.
- For 13 to 23, subtract 12 and add PM (e.g., 15:00 becomes 3:00 PM).
Minutes and seconds remain untouched.
Here’s how it looks in practice:
24-Hour Format | 12-Hour Format |
---|---|
07:30 | 7:30 AM |
00:45 | 12:45 AM |
14:15 | 2:15 PM |
23:59 | 11:59 PM |
Common Confusions and How to Avoid Them
Midnight and noon often trip people up. In the 12-hour format, 12:00 AM is midnight, and 12:00 PM is noon—but it’s easy to flip them by mistake.
Then there’s military time, where you might see 1400 instead of 14:00. The standard 24-hour format usually keeps the colon, so don’t let the shorthand throw you off.
The fix? Always double-check the context. If it’s unclear, ask which format’s in play—it saves headaches later.
Real-World Applications
The 24-hour format shines in situations where timing is everything:
- Travel: Flight schedules worldwide use it to keep things clear across time zones.
- Military: Precision is non-negotiable, and this format delivers.
- International Business: Coordinating a call between New York and Tokyo? The 24-hour format keeps everyone synced.
