of international date line only
​

Answer 1

Answer:

It is located halfway round the world from the prime meridian—the zero degrees longitude established in Greenwich, England, in 1852. The International Date Line functions as a “ line of demarcation ” separating two consecutive calendar dates. When you cross the date line, you become a time traveler of sorts!

Answer 2

Answer:

The International Date Line (IDL) is an imaginary line of demarcation on the surface of Earth that runs from the North Pole to the South Pole and demarcates the change of one calendar day to the next. It passes through the middle of the Pacific Ocean, roughly following the 180° line of longitude but deviating to pass around some territories and island groups.
