Time zone

A time zone is a region of the Earth that has the same standard time. The world is divided into different time zones to account for the fact that the Earth rotates, causing the sun to rise and set at different times in different places. Each time zone is usually one hour earlier or later than the adjacent one, although some areas may adopt half-hour or even quarter-hour differences. Time zones help people coordinate activities across various regions, such as business hours and transportation schedules, making it easier to communicate and plan events globally.
