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. The International Date Line functions as a “line of demarcation” separating two consecutive calendar dates. It corresponds along most of its length to the 180th meridian of longitude but deviates occasionally to … The prime meridian is not the only standard whose definition has changed over the years, as more precise means of measurement became available. It is an imaginary line roughly based on the meridian of 180° longitude. The conference was held at the request of U.S. President Chester A. Arthur.The subject to discuss was the choice of "a meridian to be employed as a common zero of longitude and standard of time reckoning throughout the world".
