Herein, how can I remember 12 AM and PM?

If midnight were 12 PM, then the minute before 1 AM would be 12:59 PM, which wouldn't make sense. The words come from Latin, but you can remember PM with an English mnemonic as "post-midday" -- anything after noon is post-midday, including 12:00:01 and 12:59 (one minute before 1 PM).

Beside above, what is the meaning of AM and PM in time?
