International+Date+Line

=**International Date Line**=

The International Dateline is an imaginary line 180 degrees lengthwise (or longitude)
It separates the two days that exist on the earth at the same time

At midnight, a small chunk of the earth is starting a new day
Lets say the red area is Monday while the blue area is Tuesday as you can see, majority of the world is on Monday, while the small slice of earth is already on the next day



With each hour, the red area get's bigger





now a quarter of the earth is on tuesday, while the other 3 quarters of the earth are still on monday

now exactly half of the earth are on tuesday, while the rest of the earth are on monday If a plane were to fly around the world, it wouldn't keep subtracting days or going back in time, or adding days and going into the future, as most people believe it would just keep switching between two days but since Tuesday keeps getting bigger and bigger, at one point the plane would be in the Monday area for maybe an hour and then fly into the Tuesday area for the rest of the plane trip, until it comes back into the Monday area, now even smaller then before That small blue area is Monday while the red area is Tuesday. you know that every hour, more and more of the world are starting tuesday and finishing monday From 11 to 11:59 the entire world will be red, meaning that the entire world is on Tuesday, like so The small red area in the first picture had been on Tuesday the longest, so at Midnight, the small area will start wednesday while the rest of the earth is slowly hour by hour completing Tuesday and starting Wednesday. This time, starting from the first picture, the blue area represents Tuesday while the red area represents Wednesday. The red area is once again getting bigger because the areas in blue have been blue (meaning they were on Tuesday) for 24 hours. More and more of the earth becomes red, until the entire world is on Wednesday for that small time period (11 to 11:59). The cycle starts again, with the small red area being Thursday.
