I believe it's Latin. "Ante meridiem" (currently spelled "meridian") means "before the middle" (same as an antechamber being a small room you walk through - or wait in - before you enter the main room), and "post meridiem" meaning "after the middle" - of the day, of course!

These abbreviations represent the Latin phraes ante/post meridiem, which mean 'before/after midday'. They have been in use in English since the 17th century.
