- The International Date Line (IDL) is an imaginary line running from the North Pole to the South Pole along the 180° longitude.
- The IDL serves as the "line of demarcation" between two consecutive calendar days.
- When crossing the IDL from west to east, you subtract a day; when crossing from east to west, you add a day.
- The line is not perfectly straight and is adjusted to avoid splitting countries or islands into two different dates.
Important Points
- The International Date Line is not established by any international law but is generally accepted worldwide to facilitate global timekeeping.
- The IDL deviates around countries like Kiribati, Samoa, and others to ensure they remain in the same time zone and date.
