the international date line is a line of latitude at 180 degrees on a globe it is used to tell us when a new day starts and when one ends. the meridian of greenwich is also used like this and it i found at 0 degrees. the international date line is not a straight line, is swerves around countries so it isn't one day on one side of an island and the next day on the other side.

Note that the international date line is imagined as a set of straight line segments so, it's not "swerving around" islands in the Pacific Ocean but rather straight boundry lining around them in just a very few major "kinks" . See a map or globe.

It is an imaginary line down the middle of the Pacific Ocean (with a few kinks in it to avoid inhabited land) where today changes to tomorrow (if you are travelling west) or tomorrow changes to today (if you are travelling east). It is (roughly) on the opposite side of the Earth to the prime meridian. Because we live on a round (again roughly) ball and time changes because of the earth's rotation there has to be an internationally accepted spot where the day changes.
