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 24-hour time to 12-hour time (or vice versa), use the following table:
24-hour time | 12-hour time |
---|---|
00:00 (midnight) | 12:00 AM |
01:00 | 1:00 AM |
02:00 | 2:00 AM |
... | ... AM |
10:00 | 10:00 AM |
11:00 | 11:00 AM |
12:00 (midday) | 12:00 PM |
13:00 | 1:00 PM |
14:00 | 2:00 PM |
... | ... PM |
22:00 | 10:00 PM |
23:00 | 11:00 PM |
The minutes remain the same between the two formats.
Alternately, you can use the following math to convert from AM/PM to 24-hour format:
- For AM times, use the time directly: 8:45 AM = 8:45 (in 24-hour format)
- For PM times, add 12 hours to the time: 8:45 PM = 20:45 (in 24-hour format)
