Why use Military Time Instead of 4:30 PM?
Military time exists to eliminate miscommunication when telling the time. It helps to clearly distinguish between 4:30 pm and 4:30 am. For example if a mission starts at 4:30 it’s not immediately clear whether that means 4:30 pm or 4:30 am.

1. Determine if 4:30 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 4:30 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 4:30 pm we know it is 4 hours and 30 minutes since midday.

4:30 pm is after midday so we simply take our hours since midday (4) and add 12 to get the military time in hours. That means the military time in hours is 16.
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 4:30 pm is 1630.
