Hi, I am now sharing the idea in much easier way. Zu Favoriten hinzufügen. For example if you travel across the international date line from East to West then your date will change to the next date. If you flew across the International Date Line, traveling from east to west, you would land in the next day Log in for more information. If you cross it when going west, then 24 hours are added to your time. It is the globe that rotates through time of day positions. Since the International Date Line West (IDLW) time zone represents the last place on Earth where a particular time and/or date exists, it is referred to as Anywhere on Earth (AoE). International Date Line West (GMT-12:00) The importance of international date line (west) is that if you cross the international date line then the date will change. This means that, for instance, if a deadline has not passed in the UTC–12:00 zone, the deadline has not yet passed "Anywhere on Earth". International Date Line West als Standard setzen. See, in this Fig.1 I have drawn 3 lines. The International Date Line is located at 180 degrees east or west of the Greenwich Meridian and is an imaginary line of longitude that differentiates between two different days. This is to account for the many time zones around the world to make it easier for people to know what time it is in various countries and to keep days uniform based on daylight hours. Times of day are fixed orientations on the globe in relation to the sun (12:00 noon directly faces the sun, and 12:00 midnight 180 degrees the opposite). The International Date Line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. The International Date Line, shown here as a yellow line, defines the boundary between calendar dates. If you cross the International Date Line on a journey towards the east, then 24 hours are subtracted from your time. The International Date Line (IDL), is an imaginary line that runs roughly along the 180° line of longitude, in the middle of the Pacific Ocean. International convention accepts the line as the location where one day is divided from the next, with the area in the Eastern Hemisphere one day ahead of the Western Hemisphere. Time difference from International Date Line West. Similarly, for every 15° crossed when heading east, you earn an hour and for every 15° crossed when heading west, you lose one.
