Why is the international date line not a straight line human geography?

The date line runs from the North Pole to the South Pole through the Pacific Ocean. It is not a straight line, however. The date line curves around several landmasses. For example, it curves around the islands that make up the nation of Kiribati, so that all regions of the country remain on the same day.

Why is the 180 degree meridian called the International Date Line?

180° Longitude is also called International Date Line (IDL) because the either two sides of the International Date Line have two different dates. That is why it is called INTERNATIONAL DATE LINE.

What is the IDL bent on some places?

The IDL is an imaginary line that roughly follows the 180° line of longitude and passes through the Pacific Ocean. However, this line is not straight and strays from the 180° meridian at certain points. In some places, it appears as zig-zag, deviating to the meridian’s east or west.

Which country is closest to the International Date Line?

The date line passes equidistantly between the two Diomede Islands—Little Diomede Island (US) and Big Diomede Island (Russia)—at a distance of 1.5 km (1 mi) from each island. The date line circumvents the territory of Kiribati by swinging far to the east, almost reaching the 150° meridian.

Why is the International Date Line not a straight line?

Why is the international date line not straight? An excellent way of visualizing the IDL is to think of it in terms similar to a line of longitude.

What is the International Date Line in geography?
