How to Convert AM/PM to Military Time
Converting standard 12-hour AM/PM time to military (24-hour) time is straightforward. The military time format runs from 00:00 (midnight) to 23:59 (one minute before the next midnight). This method ensures clarity, making it a preferred standard to military time system globally.
- For AM hours:
- If the hour is 12 AM (midnight), change it to 00. So, 12:XX AM becomes 00:XX. (e.g., 12:30 AM is 00:30).
- For hours 1 AM to 11 AM, the hour number remains the same. Ensure it's two digits by adding a leading zero if necessary (e.g., 9:30 AM is 09:30).
- For PM hours:
- If the hour is 12 PM (noon), the hour number remains 12. So, 12:XX PM becomes 12:XX (e.g., 12:45 PM is 12:45).
- For hours 1 PM to 11 PM, add 12 to the hour. So, H:MM PM becomes (H+12):MM (e.g., what is 3:30 pm in military time? It's (3+12):30 = 15:30).
- The minutes always stay the same.
