2. What is Military Time?
Military time, also known as the 24-hour clock, is a method of timekeeping that counts all 24 hours of the day, starting at 0000 (midnight) and ending at 2359 (11:59 PM). This system eliminates the need for AM and PM designations. It is widely used in sectors such as the military, aviation, healthcare, and emergency services due to its clarity and precision.
- How it Works: The day is divided into 24 hours. The first hour of the day is 0000 (midnight), and the hours proceed sequentially. For example, 1:00 AM is 0100, 2:00 AM is 0200, and so on until noon, which is 1200. After noon, the count continues: 1:00 PM is 1300, 2:00 PM is 1400, and so on, until 11:00 PM, which is 2300.
- Why it’s Used: Military time avoids ambiguity by using a single continuous count for the entire day. This prevents misinterpretations that can occur with the 12-hour clock system, especially in critical situations.
The U.S. Naval Observatory provides detailed information on timekeeping practices, including military time. Military time is also integral to fields that demand precision and clarity.
3. Why Use Military Time?
There are several compelling reasons to use military time, especially in professions where accuracy and clarity are paramount.

4. Converting Standard Time to Military Time
Converting standard time to military time is straightforward. Here’s how you can do it:
- For AM hours (12:00 AM – 11:59 AM): Simply add a zero in front of the hour if it is a single digit, and keep the minutes as they are. For example, 9:15 AM becomes 0915 in military time. Midnight (12:00 AM) is 0000 in military time, and 12:30 AM is 0030.
- For PM hours (12:00 PM – 11:59 PM): Add 12 to the hour. For example, 3:45 PM becomes 1545 (3 + 12 = 15). So, 8:20 PM would be 2020 (8 + 12 = 20).
- Noon (12:00 PM): Noon is represented as 1200 in military time.
Here is a quick reference table:
| Standard Time | Military Time |
|---|---|
| 1:00 AM | 0100 |
| 6:00 AM | 0600 |

| 11:00 PM | 2300 |
| 12:00 AM | 0000 |
With these simple rules, you can easily convert any standard time to its military time equivalent.
5. Converting Military Time to Standard Time
Converting military time back to standard time is also quite simple:
- If the military time is less than 1200: The time is in the AM. Simply remove the leading zero (if there is one) and add “AM.” For example, 0800 becomes 8:00 AM.
- If the military time is 1200: This is noon, so it is 12:00 PM.
- If the military time is greater than 1200: Subtract 1200 from the military time, and the result is the PM time. For example, 1500 – 1200 = 300, so 1500 is 3:00 PM.
- Midnight: 0000 is 12:00 AM.
Here’s another quick reference table for converting military time to standard time:
