Understanding Military Time: A Guide to 9 O'Clock

- 9 o’clock in the evening (military time): 2100

How to Tell Military Time

- Add the minutes: Add the minutes to the hour. For example, if it is 9 o’clock in the morning with 30 minutes, it would be 0930.
- Use the 24-hour clock: Remember to use the 24-hour clock, which means that the day begins at 0000 hours and ends at 2359 hours.
