AM stands for âante meridiemâ, which means âbefore noonâ in Latin, while PM stands for âpost meridiemâ, which means âafter noonâ in Latin. 12-Hour Periods. Most clocks today are 12-hour clocks â they divide the 24 hours in a day into two 12-hour periods.
Since midnight and noon are the meridiems referred to, it is my understanding that the two are neither AM nor PM, they are just 12:00. Not just 12, but rather 12 Noon and 12 Midnight.

Interesting info, and when referring to 12:00, I usually write it as either ânoonâ or âmidnightâ vs 12:00pm and 12:00am, or 12 noon/midnight.
