24-hour format View history

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.
