A time zone is a geographical region where all the clocks have the same standard time. Our earth is divided into 24 time zones, with each zone roughly spanning 15 degrees of longitude, because the Earth rotates 360 degrees around its axis in 24 hours. By dividing the Earth into 24 time zones, each time zone is one hour ahead or behind its adjacent zone, creating a standardized way to measure time across the globe. Time zones help to avoid confusion when communicating the time across different regions, especially in a world where people and events are increasingly global.
