Is anti meridian meaning am time day meaning sun light or night time in the morning like two am after midnight?

Questions here have to be in English.
Whilikers is correct. ante meridiem means before midday, a.k.a. before the sun is above the meridian you are on.
(if you are above an arctic circle, you may not be able to see it every day of the year)
People who talk about "12 AM" and "12 PM" deserve to be punched

AM is a shortened acronym for anti-meridian which is the 180 degree meridian. The time the sun crosses this is the point of midnight universal time and basically means hours from this point until the sun crosses the opposite meridian, zero degrees, at noon.
Post meridian (PM) meaning after, is the opposite. The time the sun crosses and after zero degree parallel or after noon.
Anti-meridian meaning before the sun crosses the zero degree meridian.
We split the 24 hours into time zones so the AP/PM is associated with your local time, One could just as effectively use 24 hour format and coordinated universal time, the AM/PM would still mean the same.
IE: Where I live, it is presently 1:57 PM, mountain daylight time,,exactly the same as 20:57 PM universal time.

It's just an imaginary line that forms a great circle on the earth. It has nothing to do with sunlight.
Noun. antimeridian The reference line at 180° longitude, on the opposite side of earth to the prime meridian. A meridian of longitude opposite to any given meridian. 123° west is the antimeridian of the 57° east meridian.
A prime meridian is a meridian in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian form a great circle. This great circle divides a spheroid, e.g., Earth, into two hemispheres. Wikipedia

The Latin "ante meridiem" means "before mid-day". 2 AM is well before noon, but there you go.
