What is the International Date Line and why is it not straight?
The International Date Line (IDL) passes through the Pacific Ocean. It is an imaginary line, like longitudes and latitudes. … To avoid any confusion of date, this line is drawn through where the sea lies and not land. Hence, the IDL is drawn in a zig-zag manner.
How was the IDL decided?
The IDL was chosen because it runs right through the heart of the Pacific Ocean, in a relatively straight line, although it does zig-zag around eastern Russia and the Aleutian Islands of Alaska. That being said, the IDL is not a part of international law, so countries are free to observe whatever dates they choose.
Why is the International Date Line spread over the ocean?
There are many groups of islands in the Pacific Ocean. These groups belong to states which do not want some islands on one side of the date line, and the rest on the other. They have therefore decided to move the date line, so that all islands are in the same time zone.

What is the International Date Line and how does it work?
The International Date Line (IDL) is an imaginary line of longitude on the Earth’s surface located at about 180 degrees east (or west) of the Greenwich Meridian . The date line is shown as an uneven black vertical line in the Time Zone Map and marks the divide where the date changes by one day.
What is an example of International Date Line?
The international date line is defined as an imaginary line that goes north and south through the Pacific Ocean, one day is on the east side of the line and the following day is on the west side. An example of the international date line is when it’s 3pm on Sunday in Samoa, it’s 3pm on Monday right across the line, just 550 miles away in Tonga .
Where does the International Date Line start?
The International Date Line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway round the world from the prime meridian —the zero degrees longitude established in Greenwich, England, in 1852.
What is the International Date Line on a globe?
International Dateline. The International Date Line sits on the 180º line of longitude in the middle of the Pacific Ocean , and is the imaginary line that separates two consecutive calendar days.
