GENERAL KNOWLEDGE

Detailed explanation-1: -The international date line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway around the world from the prime meridian-the 0 degrees longitude line in Greenwich, England.

Detailed explanation-2: -The International Date Line functions as a line of demarcation separating two consecutive calendar dates. At this longitude 180° West and East longitude meet. This line passes through the mid pacific region. If we move from the west of the IDL to the East of the IDL we will gain a day.

Detailed explanation-3: -It is an imaginary line made to go zig-zag in some regions, to avoid land area to leave island groups wholly on the same side of this line.
