Answer 1

Answer:

The International Date Line serves as the "line of demarcation" between two consecutive calendar dates. 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.

one crosses the date line at precisely midnight, going westward, one skips an entire day. while going eastward, one repeats the entire day
