Question

what is the rule of changing the date while crossing the international date line​

Answer 1

Answer:

When you cross the IDL, the day and date change. If you cross it traveling westward, the day goes forward by one, and the date increases by one. If you cross it traveling eastward, the opposite occurs. The IDL is not a matter of international law, but it's one of the few standards embraced globally.

Answer 2

Answer:

Explanation:

The International Date Line (IDL) is an imaginary — and arbitrary — line on Earth's surface that runs from the North Pole to the South Pole. When you cross the IDL, the day and date change. If you cross it traveling westward, the day goes forward by one, and the date increases by one. If you cross it traveling eastward, the opposite occurs.
