Tonga Island in Oceania is the first place in the world to enter New Year’s Day every year; and Western Samoa, which is only two or three kilometers away from it, is the newest place in the world to celebrate New Year’s Day. This interesting phenomenon is related to the internationally recognized “International Date Change Line” (referred to as the date line). It is a meridian that overlaps 180 degrees east longitude and 180 degrees east longitude. The time in the west side is one day later than the east side.
The change of date on the earth begins with the date line. In order to avoid two different dates in the same country, this line is twisted and twisted, and basically the place is the ocean. The island of Tonga mentioned above is on the west side of the date line, while West Samoa is located just east of the line. So although they are only two or three kilometers apart, the date is always a full day.
