A time zone is a region of the globe that observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the same time.

Owing to some countries having half hour time zones, there are more than 24 time zones in the world. The starting point at which Coordinated Universal Time starts is the Prime Meridian (zero degree longitude).
