Question

What is International Dateline?

Answer 1

The International Date Line (IDL) is an imaginary line extending from the North Pole to the South Pole, primarily along the 180° meridian in the Pacific Ocean, that demarcates the boundary between one calendar day and the next. Crossing the IDL from west to east subtracts a day, while crossing from east to west adds a day. To accommodate political and economic considerations, the IDL deviates around certain landmasses and territories.
