The International Date Line around the antimeridian (180° longitude). The International Date Line ( IDL) is the line between the South and North Poles that is the boundary between one calendar day and the next. It passes through the Pacific Ocean, roughly following the 180.0° line of longitude and deviating to pass around some territories and ...
The 180th meridian on a map of Earth. The International Date Line zigzags around the 180th Meridian. The 180th meridian or antimeridian[ 1] is the meridian 180° both east and west of the prime meridian in a geographical coordinate system. The longitude at this line can be given as either east or west . On Earth, the prime and 180th meridians ...
This became moot in 1995, however, when the International Date Line was moved to the east of Kiribati and that country's easternmost time zone is now the world's earliest. After they established a military base there in 1948, the Soviet government relocated the indigenous population of Big Diomede Island to mainland Russia. [9]
The International Date Line passes through the Line Islands. The ones that are parts of Kiribati are in the world's farthest forward time zone , UTC+14:00 . The time of day in these atolls is 24 hours ahead of the state of Hawaii in the United States, which uses UTC−10:00 , and 26 hours ahead of some other islands in Oceania , such as Baker ...
The international date line [note 1] in Judaism is used to demarcate the change of one calendar day to the next in the Jewish calendar. The Jewish calendar defines days as running from sunset to sunset rather than midnight to midnight. So in the context of Judaism, an international date line demarcates when the line of sundown moving across the ...

[ 1] From 1884 to 1974, the Greenwich meridian was the international standard prime meridian, used worldwide for timekeeping and navigation. The modern standard, the IERS Reference Meridian, is ...
The international date line runs between the south pole and the north pole, serving as a boundary between one calendar day and the next. Crossing the date line going west increases the date by one ...
A prime meridian is an arbitrarily -chosen meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides a spheroid, like Earth, into two hemispheres: the Eastern ...
