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.
The Greenwhich meridian also Prime Meridian is 0 degrees longitude and International Date Line roughly follows the 180° longitude or antimeridian. The antimeridian is the meridian which is 180° east or west of the Prime Meridian.
