Question

What is international date line describe the use of this line

Answer 1

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. It is located halfway round the world from the prime meridian—the zero degrees longitude established in Greenwich, England, in 1852.

Answer 2

ANSWER_✌️

Since demonstrations will be easier to learn, I will try answering that way..

Start with a sheet of world map, cut near the international date line [with Japan & Alaska on either sides] & make them understand 3 key points:

1. Sun's movement over the earth is always east to west.I.e., Sun moves from Japan to America (a torch light in a relatively darker room might brighten your point)

2. The time when a particular geographic area is illuminated by Sun is the daybreak for that country e.g. sunrise for France comes after it has crossed over Indonesia for the same date XX/XX/XXXX.

3. Every new rotation.i.e., movement of Sun from east to west, is a new day.

Moving over to a globe from the map, the above steps can be visualized better.

Now,show them the difference in time & date on while movement happens across the date line from either side.✔️
