An interval is a subset of an order-numbered set; the interval includes a highest- numbered member of the subset and a lowest-numbered member of the subset and all members of the set with order numbers with values between that of the highest- and lowest-numbered members. This is more exactly called a "closed interval". An "open interval" is defined in the same way, except that the lowest-numbered and highest-numbered limits are not part of the subset.
If you are asking about time-related A M and P M then it means - Ante meridian and post meridian. "Ante" is Latin for "before", "post" means after.Meridian is when the sun reaches its zenith, the highest point in its daily arc; i.e., noontime.
AM = "Ante - Meridian"PM = "Post - Meridian""Ante" and "post" mean "before" and "after"."Meridian" is the imaginary line in the sky that runs north/south and passes directly over you.In the morning, the sun moves from the eastern horizon toward the meridian. At Noon, the sun crosses the meridian. In the afternoon, the sun has crossed the meridian and moves away from it toward the west.Morning is the time before the sun crosses the meridian = Ante-Meridian = AM.Afternoon and evening is the time after the sun crosses the meridian = Post-Meridian = PM.
There are 360 degrees. They are numbered 0, 1-179 East, 180, and 1-179 West.360 degrees.On the earth, there is the Greenwich Meridian = 0 deg;1 - 179 East and 1 - 179 West;and 180 deg, much of which forms the International Date Line.
Time before noon. Before the use of standard time, (Greenwich Mean Time, time zones, etc.) most communities used solar time. Every town had its own standard of time. Noon was when the sun reached its highest point in the sky on any given day. Solar noon happens at the moment of the sun's transit of the meridian; the geographical north- south imaginary line directly overhead that the sun and other celestial bodies cross. Before the sun crosses the meridian it is morning. After the sun crosses the meridian it is afternoon (post meridian). In modern times we still use the a.m. and p.m. designations, even though they are not technically correct.
The Prime Meridian is numbered zero degrees. Meridians, or lines of longitude, are numbered with increasing numbers of degrees both east and west of the Prime Meridian. On the opposite side of the world from the Prime Meridian is 90 degrees, which is also the International Date Line.
I am not sure, but i think it is the prime meridian, pretty sure i am not right

Parallels are numbered based on their angular distance north or south of the Equator, with the Equator itself as 0 degrees. Meridians are numbered based on their angular distance east or west of the Prime Meridian (located in Greenwich, England), with the Prime Meridian itself as 0 degrees.
Parallels are numbered north or south from the equator (starting at 0 degrees) towards the poles, with the equator at 0 degrees. Meridians are numbered east or west from the Prime Meridian (located at 0 degrees) towards the International Date Line, with the Prime Meridian at 0 degrees.
Ante meridian and post meridian. "Ante" is Latin for "before", "post" means after. Meridian is when the sun reaches its zenith, the highest point in its daily arc; i.e., noontime.
The highest longitude lines are the prime meridian at 0 degrees longitude and the 180 degrees longitude line. These lines mark the starting point for longitude measurements to the east and west, respectively.
Valletta, the capital of Malta, is centered about 14.52° east of the Prime Meridian. There's no such thing as a place that's north or south of the Prime Meridian. The Prime Meridian covers all latitudes that exist, from the highest one to the lowest one.

Uranium, with atomic number 92, is the highest numbered element in the periodic table that is found in nature.
Yes. Every "meridian" is an imaginary line on the Earth that joins the north and south poles and has the same longitude at every point on it. The Greenwich meridian is the one that passes through the Royal Observatory in England. It's defined as zero longitude, and all other longitudes on Earth are numbered starting at that one.
180° is halfway around a circle or a sphere. Beginning at the Prime Meridian, you can travel EITHER east OR west, and after you have traveled 180 degrees, you'll arrive at the same line either way ... the meridian of 180° E and W longitude, which is halfway around the Earth in either direction from the Prime Meridian.
