Quick Answer
A time zone is a region of the Earth that uses the same standard time. Time zones help coordinate daily life across different longitudes.
The Full Story
Time zones were created to standardize timekeeping as railways and telegraphs made long-distance coordination more important in the 19th century. Earth is divided into roughly 24 main zones based on its rotation, though real boundaries are often irregular because countries and regions choose their own standards. The prime reference line is the Prime Meridian in Greenwich, London, which defines Coordinated Universal Time as UTC. Some places also use half-hour or quarter-hour offsets.
