How the Military Time Converter (24-Hour to 12-Hour) works
Military time numbers the hours 00 to 23, so no AM or PM is needed. 1:00 PM is 1300 and midnight is 0000.
From 12-hour time: 12 AM becomes 00, hours 1 to 11 AM stay the same, 12 PM stays 12, and 1 to 11 PM add 12.
The formula
PM hours (except 12 PM): 24-hour = 12-hour + 12; 12 AM = 00
Worked example
Using the default values shown in the calculator:
| Convert from | 24-hour (military) time |
|---|---|
| 24-hour time (HHMM, e.g. 1830) | 1830 |
| Hour (1-12) | 6 |
| Minutes | 30 |
| AM or PM | PM |
- 1830 is 6:30 PM.
- That is 1,110 minutes after midnight.
Result:
| 12-hour time | 6:30 PM |
|---|---|
| Military time | 1830 |
| Spoken (military) | 18 30 hours |
| Minutes since midnight | 1,110 |
