Explanation of 21:42 to 9:42 PM conversion

To convert 24-hour time (also known as Military Time) 21:42 to 12-hour time we need to do a few simple steps. 

If the number of hours of our 24-hour time is greater than 12, we need to subtract 12 from it. Otherwise, if it less than or equal to 12 we just leave it as it is. And the last rule is 0 becomes 12 AM. If the number of hours is greater than or equal to 12 then it will be considered PM, otherwise it's AM.

In our case the hour 21 is greater than 12, so we need to subtract 12 from 21 to get 12-hour format:

21 - 12 = 9

The hour part of our 24-hour time (21 ) is greater than or equal to 12, so it's

PM (latin Post Meridiem - After Midday) time

After we got the number of hours and found out the right AM/PM postfix we just need to add minutes to it. When converting 24-hour time to 12-hour time, minutes remain unchanged (:42). Finally, let's put it all together:

9:42 PM
