Explanation of 10:21 AM to 10:21 conversion
To convert 12-hour time 10:21 AM to 24-hour time format (also known as Military Time) we need to do a few simple steps:
- If our 12-hour time is PM (after midday) and the number of hours is not equal to 12, we will add 12 to it.
- If our time is AM (before midday) and the number of hours is equal to 12, then it will be 0 hours in 24-hour (Military) time format.
- In any other case we just leave the number of hours untouched.
- And finally we remove AM/PM postfix. Yes, it's that simple.
In our case (10:21 AM) the number of hours is not equal to 0, and it's AM, so we keep it untouched:
