We have different time zones because if we all set our clocks to the same time noon would be the middle of the day in some places, but it would be morning, evening and the middle of the night in others. Since different parts of the Earth enter and exit daylight at different times, we need different time zones.
In order to build the time zone map, they studied Earthâs movements. As the Earth rotates on its axis, it moves about 15 degrees every 60 minutes. After 24 hours, it has completed a full circle rotation of 360 degrees. The scientists used this information to divide the planet into 24 sections or time zones. Each time zone is 15 degrees of longitude wide. Distance between the zones is greatest at the equator and shrinks to zero at the poles, due to the curvature of the Earth. Since the equator is approximately 24,902 miles long, the distance between time zones at the equator is approximately 1038 miles.
