When you cross the International Dateline while traveling from east to west,
then at some convenient time before you reach your destintion, you must
crank your calendar wristwatch forward 24 hours, and tear an extra daily page
off of your desk calendar. If you forget to do this, then once you land, everyone
you meet there will disagree with you on the date. They'll all say that your clock
and calendar are way slow, that you are stuck in yesterday, and that it's actually
a day later than you think it is. This could be especially awkward if you think it's
Saturday and everybody around you is heading for Church.

The closest continent east of the International Date Line is North America.
When crossing the dateline and proceeding to the west, you lose a day. You tear a daily pagefrom your calendar, and crank your wrist-watch forward 24 hours.
west
Nuku'Alofa, the capital, is about 300 miles east of the IDL.
Nothing in particular happens; if you happen to be napping aboard the ship at the moment of crossing, you can sleep right through it, just as you do when crossing any other meridian of longitude. By international agreement, however, your calendar date becomes one less when you cross the International Date Line going east.
The International Date Line is an imaginary line of longitude of 180 degrees around the Earth. It works when a person crosses the line from the east to the west a day is added. The opposite effect happens when crossing from west to the east with a day subtracted.
French Polynesia is east of the International Date Line.

There is no such meridian. A day is repeated when the travelercrosses the International Dateline from west to east.
