Why use Military Time Instead of 10:15 AM?
Military time exists to reduce miscommunication when telling the time. It helps to clearly differentiate between 10:15 am and 10:15 pm. For example if a mission starts at 10:15 it’s not immediately clear whether that means 10:15 am or 10:15 pm.
How to Convert 10:15 AM to Military Time
1. Determine if 10:15 am is before or after midday
We can tell this by looking at whether the time is followed by am or pm. A.M. is an abbrevation of ante meridiem, which is Latin for before midday. That means 10:15 am is before midday.
2. Calculate the hours and minutes since midnight
Before we can convert to military time we need to know how much time has passed since midnight. At 10:15 am we know it is 10 hours and 15 minutes since midnight.
3. Convert hours to military time
10:15 am is before midday so we simply take our hours since midnight (10) and because it is two digits that is already correct for military hours. That means the military time in hours is 10.
4. Combine the hours and the minutes
The military time in minutes is the number of minutes calculated in step two which is 15. Military time is given as four digits with the hours first, so the military time for 10:15 am is 1015.
