The International Date Line is located at which longitude?

Explanation:
The International Date Line sits along the 180th meridian, opposite the Prime Meridian (0° longitude). This is the line where the calendar date changes as you cross it, and it’s why maps commonly show it at 180° longitude. In reality the line curves around some islands and territories to keep time zones and political boundaries intact, but its general location is the 180° line. That’s why 180 degrees of longitude is the best answer, with -180° representing the same line in the opposite direction.
