What happen when your crossing the IDL westward?

Answer 1

NOTHING!  lol  =))

Seriously, you would skip one day (i.e. advance the date) and continue your date and time keeping from the new date.

If travelling eastward you need to 'r****d one day' (i.e. you repeat the same day again.

In general terms the world is divided into time zones. With a number of exceptions they are spaced 15 degrees longitude apart. (180 degrees East + West = 360, 360 degrees divided by 24 hours for the rotation of the earth = 15 degrees for one hour). However, the sun rises not according to zone time but rather at a different time for each longitude and for each fraction of longitude.

Presume for a moment that the dateline is the place where the sun appears first in a day. If you are at 165E "YOUR" sunrise would be 1 hours later. Then you would have to say that on the other side of the date line it will still take a whole day until sunrise is observed there.

So the eastern side of the dateline is 24 hours ahead of the western side.

Hope this makes sense to you.
