International date line

The video explains how the International Dateline affects time perception between two neighboring islands, Little Diomede and Big Diomede. It describes how the dateline, which follows the 180° longitude, causes a day difference between the islands. The video further elaborates on how the Earth's rotation affects global time zones, leading to different days in different parts of the world. Crossing the dateline results in an immediate change of day, illustrating a form of time travel.
