What is the International Date Line
Definition of the International Date Line
The International Date Line (also called the Date Line), an imaginary line that runs between the Arctic and the South Pole, separates each day from the next day and corresponds most of it to a 180 ° longitude. However, it veers east across the Bering Strait to avoid the division of Siberia and veers west to annex the Aleutian Islands with Alaska. There is another eastward direction south of the equator, which allows some island groups to be on the same day with New Zealand. So this line is not a straight line, it deviates around many land areas, to make countries share the same day.
Working principle of longitude
If there is one person in New York and another in California talking over the phone, the timing at each of them varies, by three hours, to be precise, because New York and California are in different time zones. If the individual is in Hawaii and the time is 9 am on Thursday, at the same time in England, there will be 9 pm on Thursday, while in the east in New Zealand, which is in almost the same section as Hawaii, it is actually 9 am on Friday the next day, because between Hawaii and New Zealand the international dateline, which separates the build every day and the next.
Working principle of the dateline
The Earth is divided into sections extending from pole to pole by imaginary lines ( meridians), anything circular or oval can be divided into 360 degrees, the earth is almost oval, and therefore can be divided into 360 equal sections and each section width up to 15 degrees, and when Divide 360 by 15 and the result is 24, so there are 24 different time zones on the earth, each one increasing by one hour if the direction is east, and time decreases by one hour if the direction is west, that means 24 hours a day, for 24 time zones.
