when u travel from west to east u gain a day while when u travel east to west u lose a day. it means that when u go from west to east u are one day ahead from west and when u go to west from east u are one day back from east.

if you travel east across the international dateline your calendar would be moved back a day.If you traveled west, you would move your calendar a day ahead.Weird, huh?
When traveling from west to east then yes, you lose a day. But, when travelling from east to west you gain a day. Example: American Samoa is east of the dateline and independent Samoa is west of the dateline, although there is only about 60 nautical miles between the islands. So Wednesday in American Samoa is Thursday in independent Samoa.
The International Date Line passes through the Pacific Ocean. It is an imaginary line that runs from the North Pole to the South Pole, mostly along the 180° longitude line.

North America is on the east of the International Dateline.
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.
French Polynesia is east of the International Date Line.
When traveling east, the time around you instantly becomes a day earlier.You wind your wrist watch 24 hours backward, glue the last day back ontoyour calendar, and you 'gain' a day, because you get to live that 24 hoursover again. I'm not sure whether you'd call that 'add' or 'subtract'.
