In radio, AM stands for amplitude modulation.In TIME, it stands for Ante-Meridian (ref. the Prime meridian)Amplitude modulationAnte Meridian as in 11:00 AM (and PM is Post meridian)
"PM" stands for post meridiem, which is Latin for "after midday." It is used to indicate the time in the afternoon and evening on a 12-hour clock system.
The P stands for Post and the M stand for Meridian.From the Latin, Post means after, and Meridian means midday (noon).So the abbreviation PM as it pertains to time stand for after-midday or afternoon.
