In a 24-hour format, time is represented with unique hours of the day that do not require the AM and PM indicators. To convert from 12-hour time to 24-hour time, use the following table:
| 12-hour time | 24-hour time | Converting the Hour from 12 to 24 hour time |
|---|---|---|
| 12:00 AM (midnight) - 12:59 AM | 0:00 - 0:59 | Use 0 for hour. |
| 1:00 AM - 11:59 AM | 1:00 - 11:59 | Do nothing. |
| 12:00 PM (noon) - 12:59 PM | 12:00 - 12:59 | |
| 1:00 PM - 11:59 PM | 13:00 - 23:59 | Add 12 to hour. |
The minutes remain the same between the two formats.
