Where is the International Date Line?

The International Date Line (IDL) is an imaginary line of navigation on the surface of the Earth that runs from the north pole to the south pole and demarcates the change of one calendar day to the next. It passes through the middle of the Pacific Ocean, roughly following the 180° line of longitude but deviating to pass around some territories and island groups.

Here are some interesting facts about the International Date Line:

• It's not recognized as a legal entity. Any day just has to start and end somewhere. It was created as a matter of convenience.
• Anyway, the line is drawn in most maps.
• The line was moved several times by different countries. For example, Kiribati moved it in 1995 so the entire island country was on the same side. So, the date line is not straight - it zigzags.
