What are time zones simple explanation?
A time zone is an area that observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries between countries and their subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time.

How many different time zones are around the world?
As it is night in some parts of the world while it is day in other parts, different places in the world have different times. This is why the world is divided into 24 different time zones.

What you may know as the prime meridian — or more formally the Greenwich Meridian — is the initial division line for all time zones. It’s where dividing the Earth up into regions effectively starts. The prime meridian is an imaginary line — invisible by all rights — that runs from north to south along the 0 degree longitude line of Earth.
