How to convert 03:21 from 24-Hour Time to 12-Hour Standard Time
It is easy to convert from 24-hour time to 12-hour time once you know a few tricks. The primary difference between the two is that the hours in a 24 hour clock go all the way up to 23 (from 0 to 23). In a 12-hour clock, the hour resets to 1 after noon (midday). Follow the steps below to convert 03:21 to 12-hour time.
- First, determine whether or not 3 is greater than 12 (recall that this is one of the distinctions of the 12-hour clock, there are no hours "greater" than 12 on it)
- Since 3 is lower than 12, there isn't much to do! We can just add the "AM" designation to the end of the time: 3:21 AM
