that you tore off of your calendar, and you glue it back on.

When you cross the International Date Line traveling from Asia to North America, you will lose a day. This is because the Date Line serves as the boundary for calendar days; when you cross it from east to west, you subtract a day. For example, if it's Monday in Asia, upon crossing the Date Line, it will be Sunday in North America.
When you cross the IDL from east to west ... like going from the US to Japan ... you move your watch and calendar to read a day later. You skip over 24 hours, and you 'lose' them. When you cross it going from west to east ... like toward the US and Canada from Asia ... you move your watch and calendar to read a day earlier. You get to live the same 24 hours all over again, so you 'gain' a day.
Becuase when you cross the Dateline, The time zone changes ahead because of how the hour changes 24 times in the world, It would be excaclty a day later. When you cross the Dateline It would be tomorrow, or yesterday. Whichever way you cross.

The International Date Line is an imaginary line that runs from the North Pole to the South Pole. It marks the boundary between one calendar day and the next. When you cross the line, you either advance a day when traveling east or go back a day when traveling west.
