ante meridiem (a.m., from Latin, literally "before midday") and post meridiem (p.m., "after midday").

“AM” stands for the Latin phrase Ante Meridiem —which means “before noon”—and “PM” stands for Post Meridiem : “after noon.” Although digital clocks routinely label noon “12:00 PM” you should avoid this expression not only because it is incorrect, but because many people will imagine you are talking about midnight instead. The same goes for “12:00 AM.” Just say or write “noon” or “midnight” when you mean those precise times.
It is now rare to see periods placed after these abbreviations: “A.M.” , but in formal writing it is still preferable to capitalize them, though the lower-case “am” and “pm” are now so popular they are not likely to get you into trouble.
Occasionally computer programs encourage you to write “AM” and “PM” without a space before them, but others will misread your data if you omit the space. The nonstandard habit of omitting the space is spreading rapidly, and should be avoided in formal writing

AM is ante meridian and PM is postmeridian. In this case- ante meridian stands for the time before the sun reaches it's highest point in the sky which is commonly noon. Postmeridian stands for the time after noon.
Hope this helps and have a great day!!!

Ante Meridian and Post Meridian are Latin for "Before Noon" and After Noon." 12:00 noon technically is neither one, but we write it as P.M. because even a split second later, it's P.M.

Ante (before) Meridian and Post Meridian. It refers to time keeping. "A.M." is the morning, and "P.M." is after noon. The "meridian" is an imaginary line drawn on the face of the Earth where the division takes place.
