🌍 INTERNATIONAL DATE LINE 🌍

Local time is one of the places at the same longitude line. But local time of places located at different longitude lines is different. The earth rotates from west to east, so in the longitude lines in the east, morning and noon,night are in the places before and then on the west side of the longitude line, there are morning and afternoon,night. Greenwich's longitude line is rated as zero degree. In the places located in the east from the greenwich, the difference between the distance of every 1 ° distance is more than 4 minutes, and in the west, the difference between the distance of every 1 ° lathe is less than 4 minutes. Earth rotates 360 ° in 24 hours, that is, the Earth rotates by 15 ° per hour. As such, the world is divided into 24 distinct time zones. This difference of time for the difference of the longitude line is that, at 0 ° longitude (Greek), at some local time, at 12 noon, 180 degrees east longitude will be 12 o'clock in that day. On the other hand, the position of 180 ° West longitude will be 12.00pm on the previous day. Time difference between 180 degrees east and 180 ° west longitude line is 24 hours. In order to solve this problem, the 180 ° longitude line in the "International longitudinal meeting" held in Washington, Washington, was marked as "Date Separation Line" in 1884. Another name for this article is the "International Date Line".

 

The international date line is not straightforward. For the benefit of the local residents, the line has slightly curved slightly east or west. If a preceding ship or airline crosses the international date line, one day decreases its calendar and one day increases the time for the westward ship or airplane. Various local times are seen in different parts of the country, due to change in the longitude of the long line. In order to facilitate various works, each country has run an intermediate linear line with the longitude line of evidence and according to the time of the revision, the activities of the whole country are run.
