Date line – Based on international agreement, at midnight a new day begins here on Earth. It passes through the Arctic Ocean, along the meridian 172.50 east longitude, the Bering Strait and the Pacific Ocean far from populated areas. In the case of crossing this line from north to south, a person finds himself in an area in which the day is still ongoing, and when crossing from west to east, he immediately finds himself in that part of the planet where the coming day has already begun.
