Under the Hood
How the International Date Line Works
The International Date Line is an imaginary boundary on Earth where the calendar date changes by one day.
01
It generally follows the 180° longitude area across the Pacific Ocean, but it bends around some countries and island groups. These adjustments help keep nearby territories on the same calendar date.
02
If you are wondering where is the international date line, it runs mainly through the Pacific Ocean, far from many major land areas.
03
The international date change line helps maintain an organized global calendar. When crossing it in one direction, the date moves forward by one day. Crossing in the opposite direction moves the date back by one day.
