Answer:

International Date Line is important for knowing the days as we cross the International Date Line (IDL) from the east to the west, a day is subtracted. For example, if it is Sunday in New Delhi, it will be Saturday in New York. But if we cross the IDL from the west to the east, a day gets added.
