Antimeridian

The Antimeridian is the +/-180 degree line of longitude, exactly opposite the Prime Meridian. It is often used as the basis for the International Date Line (IDL) because it passes through the open waters of the Pacific Ocean. However, this is a simplification of the actual IDL, which curtails several countries.
