Why is it that there are different time zones?

Answer 1

Time zones were designed to create a "common time" for everybody. Specific statements like "morning", "noon" and "midnight" all have connotations of daylight and darkness. Instead of choosing one city or country and making the rest of the world revolve around it (literally), time is split along the hour breaks the rotation of the earth longitudes. Using this system, everybody has their "local noon", and concepts in poetry, novels, movies, and even diary entries all make sense, no matter your location in the world. To coordinate an exact time worldwide, Greenwich Mean Time/UTC is normally used as the "one clock". In addition, it allows time travel when flying west past New Zealand.

Answer 2

So that "daytime" coincides with the time when it is daylight.

If it is 12:00 noon in London, if there were no time zones then it would be 12:00 noon in San Francisco..... but would still be dark there are the sun isn't overhead in San Francisco until 8 hours later.
Time is measured on a system that is based on The Sun being directly overhead in the day and directly opposite being directly overhead at night. . . because the Earth is constantly turning relative to the Sun, the overhead locations constantly sweep across the land and sea.

The time a mile away is different than the time where you are, but that would really be confusing! So the Earth has been divided by people into Time Zones that are wide enough to not be confusing, but close enough that anywhere in a certain time zone is pretty close to the same time everywhere in the time zone.

Answer 3

There are different time zones because since the Earth rotates, different places get sunlight at a different time. If there were no time zones, 11:00 am would be near noon in one place, near midnight in others, and some places evening and early morning.

Answer 4

Time zones exist because the Earth is divided into 24 longitudinal sections which are roughly 15 degrees wide. This division allows for a standardized way to measure time across different regions of the world based on the position of the sun. Each time zone represents a one-hour difference in time from the adjacent zone to the east or west.

Answer 7

Because of the location of objects on the Earth. Not everything is in one place.

Answer 8

Because the earth is always rotating on its axis, and there is only one sun, so at noon the sun will be above you.
