The street changes the international day

The Earth turns from West to East, morning, noon, afternoon, and evening appear in the world in a recurring manner. So where should a new day on Earth start and end?

This issue has had many debates and also happened many mistakes and troubles. That said, in the 19th century, a small town near Ivancoxevich, Russia had a postal worker 7 am on September 1 hitting a telegram for the Chicago post office. But the answer said that it was received at 9: 28 minutes on August 31 . This made no one understand why the electricity was sent in September, the recipient received it in August ? Things like that often happened.

In order to avoid the chaos of the day, the International Conference on the Meridian Meeting in Washington in 1884 set a way to change the international day . This line is located on the longitude 180 in the Pacific Ocean. This is the line between "today" and "tomorrow ". To avoid having 2 countries in the same country, this line is not actually a kink. The path starts from the North Pole, through the Bering Strait, the Pacific Ocean, until the Antarctic . So it will not go through any country. Midnight on this road is exactly 0 hours, local time. As a rule, every time you cross this road, the date will have to change. Going from West to East over here is an extra day. Going from East to West must be reduced by 1 day.

The international date change line is the beginning and end of a day, so the East 12 Time Zone that it passes becomes a special time zone. In this time zone, the time is uniform but the date is not uniform, only 1 bar apart. So it is a day difference, one day west of the East one day. Those who live on the Kamchatka peninsula will welcome the earliest new year in the world, while those living in Alaska will have to wait another day and night to eat New Year, while they are only a short distance apart.
