The Prime Meridian is the imaginary line defined as zero longitude. It joins the
north and south poles and passes through England, Spain, France, Mali,
Burkina Faso, Togo, Ghana, and Antarctica. On its way through England, it
crosses a certain mark on the floor of a certain room at the Royal Observatory
in Greenwich, outside London.
The meridian of 180° longitude is exactly opposite the Prime Meridian and
together, they form a complete circle. That meridian also joins the north and
south pole, and passes through the Pacific Ocean for most of its length.
The International Dateline roughly follows the meridian of 180° longitude, but
departs from it with zigs and zags in several places, in order to avoid splitting
any single state, country, or island group into two different calendar dates.
No. The Prime Meridian is. The International Dateline nominally (but not exactly) follows the 180° meridian ... exactly opposite and half a world away from the Prime Meridian.
Midnight, on the morning of the day after.
the great circle is formed by the prime meridian and the international date line
Most world maps are drawn with the Prime Meridian at or near the center and the International Date Line at or near the left and/or right edge(s).
There is no deviation of the Prime Meridian. There are a few deviations of the International Dateline, but none of them is anywhere near 3,000 miles away from the meridian of 180 degrees longitude.

no the international dateline is 180 degrees, but the meridians; or prime meridian is 0 degrees.

Longitude. Prime meridian and international dateline are also included.
I have a feeling that the meaning of "it" in this question is of paramount significance, and that if we but knew it, an answer would be possible.

international dateline
The 180th meridian or antimeridian is the meridian which is 180° east or west of the Prime Meridian ... It is common to both east longitude and west longitude. It runs through the Pacific Ocean, and was the nominal guideline for the position of the International Dateline, although the dateline itself had to depart from the antimeridian in several places.
