Questions about this tool
What is 20:00 in 12-hour time?
Subtract 12 from 20 to get 8, so 20:00 is 8:00 PM.
Is 00:30 half past midnight?
Yes. 00:30 is 12:30 AM, thirty minutes after midnight.
Why is noon written as PM?
Noon starts the second half of the day, so every time from 12:00 to 23:59 takes PM.
