What country does the international date line pass threw the most?
The International Dateline doesn't cross any city, state, country, or island group.
It was intentionally planned that way, in order to avoid splitting any of them into
two different calendar dates.
If the International Date Line was a straight line it would be the 180Â° longitude line. The line intersects part of Russia (eastern part of Siberia) as well as some some territories and island groups such as Fiji. The 180Â° longitude line also goes between in New Zealand and its territory Chatham Islands such that New Zealand is in the eastern hemisphere and the Chatham Islands is in the western hemisphere.
The International Date Line is 180 degrees longitude. By international agreement, the 180th meridian, halfway around the world from the Prime Meridian, has been selected as the line from which each new day will begin. Between any meridian where it is midnight and traveling to the east through all the meridians where it has already been midnight up to the International Date Line, it is the new day. The International Date Line is somewhat irregular…
The international date line is the line which help us to mark the end of a day and the beginning of a new day. This lies in the middle of the pacific ocean and passes through some islands, if it was a straight line than a single state or country will be in different time zones. To avoid this confusion it is a crooked line.
The International Date Line is NOMINALLY the meridian of 180 degrees longitude (both east and west). The actual date line has been defined with a few bumps and jogs in it that depart from 180 degrees, in order to avoid cutting through island nations. (That would have put two different calendar dates in the same country.)
