yes.
The 12-hour clock is a timekeeping convention in which the 24 hours of the day are divided into two periods called ante meridiem (a.m., from Latin, literally "before midday") and post meridiem (p.m., "after midday").

The 12-hour clock is a timekeeping convention in which the 24 hours of the day are divided into two periods called ante meridiem (a.m., from Latin, literally "before midday") and post meridiem (p.m., "after midday"). Each period consists of 12 hours numbered 12 (acting as a zero), 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11. The a.m. period runs from midnight to noon, while the p.m. period runs from noon to midnight. The most common convention is to assign 12 a.m. to midnight and 12 p.m. to noon, defining both half days to have a closed (inclusive) beginning and open (exclusive) end. 12 noon and 12 midnight can more clearly and correctly express these times.

A.M. = Ante Meridian (12:00 in the morning-11:59 in the afternoon)
P.M. = Post Meridian ( 12:00 in the afternoon - 11:59 at night)

A.M. and P.M.
A.M. means Ante Meridian, or before the sun passes over your closest Meridian or nearest Longitudinal demarcation.
P.M means Post Meridian, or after the sun passes over your closest Meridian.
Although most Meridians or Longitudinal lines are straight, many have been "altered" to fit within geographical or political boundaries, in an effort to keep the timezone of one area uncomplicated.
In the Continental US we have 4 time zones, separated by 3 meridians or Longitudinal lines.
I hope this helps

Yes, they're abreviations for Latin on the 12-hr clock & started somewhere in the mid-1600s
am = ante meridiem -- before midday
pm = post meridiem -- after midday
