Explanation of 21:21 to 9:21 PM conversion

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

  • If the hour of our 24-hour time is greater than 12, we subtract 12 from it.
  • If the hour is less than or equal to 12, we just leave it as it is.
  • Special case: 0 becomes 12 in 12-hour format.
  • If the hour is greater than or equal to 12, the time is PM, otherwise it's AM.
(when converting 24-hour time to 12-hour time, minutes remain unchanged)

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 (:21). Finally, let's put it all together:

9:21 PM
