am stands for ante-merdian, before the sun reaches it's highest point at noon. pm is post-meridian, as the apparent angle of the sun declines. That why the time is different in the pacific, central, and eastern time zones.

12:01 (noon)-11:59 ( 1 minute before nidnight).
They are from Latin. THe Latin word meridiem (meridian as we know it) is a combination of medius (middle) and dies (day).
