You either gain or lose a day - depending on which direction you're travelling.
very true!!!!!
A Naval certificate for crossing the international date line.
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.
Crossing the International Date Line travelling to the east results in a day or 24 hours being subtracted from your time prior to arriving at that position, so that the you have to repeat the date to the west of the line. Crossing west results in a day being added, that is, the date is the eastern side date plus one calendar day. The line is necessary in order to have a fixed boundary on the globe where the calendar date resets
The International Date Line separates Day 1 from Day 2 across the globe. Thus, if you are crossing the Internationa Date Line, you may be a day ahead or behind of the place you have travelled from.
If you travel east from North America, crossing over the Atlantic Ocean, you would not cross the International Date Line to reach China.If, instead, you travelled west from North America, crossing over the Pacific Ocean, you would cross over the International Date Line to reach China.
East (Paris) is always ahead with the exception of crossing the international date line.
Beijing is almost exactly opposite Washington, D.C., with a 12-hour time difference, so you can either fly east over the Pacific, crossing the International Date Line, or you can fly west over Asia and Europe, not crossing the IDL.
No, the international date line is a line of longitude, not latitude.
If you are crossing date line from west to east you'll gain one day.
As the twins where being born they were crossing the international date line, one could have been born Sunday and the other Saturday while crossing the International Date Line, going east to west.
No. Crossing the line from west to east, Sunday becomes Saturday.
