time change
You don't gain a day by traveling West, only by traveling East. You lose a day going West.
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.
You do not lose a day if you go from March 12 to March 11. You get to live March 11 again.
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.
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.
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.
The International Date Line is the meridian where the date changes by one day when crossed east to west. This happens in order to account for the time difference between different parts of the world. Crossing the International Date Line from east to west, you "gain" a day, and crossing from west to east, you "lose" a day.

Travelers crossing the international dateline should move their clock forward by one day when traveling west to east, and back by one day when traveling east to west. It's important to adjust your watch and devices accordingly to avoid confusion. It's also advisable to check and confirm the local time of your destination upon arrival.
The date on the eastern side of the date line is one day ahead of the date on the western side. As you travel across the International Date Line from west to east, you gain a day, and as you travel from east to west, you lose a day.
There is no such meridian. A day is repeated when the travelercrosses the International Dateline from west to east.
