Why use Military Time Instead of 10:30 PM?
Military time was created to minimize miscommunication when telling the time. It helps to clearly differentiate between 10:30 pm and 10:30 am. For example if a departure time is stated as 10:30 it’s not immediately clear whether that means 10:30 pm or 10:30 am.

1. Determine if 10:30 pm is before or after midday
We can tell this by looking at whether the time is followed by am or pm. P.M. is an abbrevation of post meridiem, which is Latin for after midday. That means 10:30 pm is after midday.
2. Calculate the hours and minutes since midday
Before we can convert to military time we need to know how much time has passed since midday. At 10:30 pm we know it is 10 hours and 30 minutes since midday.
3. Convert hours to military time
10:30 pm is after midday so we simply take our hours since midday (10) and add 12 to get the military time in hours. That means the military time in hours is 22.
4. Combine the hours and the minutes
The military time in minutes is the number of minutes calculated in step two which is 30. Military time is given as four digits with the hours first, so the military time for 10:30 pm is 2230.
