Is morning 12 AM or pm?
There are no standards established for the meaning of 12am and 12pm. It is often said that 12am Monday is midnight on Monday morning and 12pm is midday. This puts all the times beginning with 12 and ending with am in the same one-hour block, similarly with those ending with pm.
Why do we use am or pm?
The abbreviation am stands for ante-meridiem (before the Sun has crossed the meridian line), and pm stands for post-meridiem (after the Sun has crossed the meridian line). At 12 noon, the Sun is at its highest point in the sky and directly over the meridian. It is therefore neither ‘ante’ (am) nor ‘post’ (pm) meridiem.
