Why do time zones exist?

Time zones exist to help manage the practical aspects of timekeeping and organization across different places on the Earth, especially in relation to navigation, scheduling, and communication across vast distances. The Earth rotates on its axis, causing the sun to appear to move across the sky from east to west, meaning that different parts of the world receive the sun's light at different times. Time zones are based on lines that run from pole to pole, roughly following longitudes, which divide the Earth into 24 time zones, each spanning 15 degrees of longitude. This system helps to standardize time across large distances, simplifying scheduling for business, transportation, and other practical purposes. It also facilitates coordination between regions and allows for a more efficient use of daylight hours.

Time zones exist to standardize the measurement of time across different geographic locations. Without time zones, each location would have to use its own local time, making it difficult to coordinate activities, communicate effectively, and manage schedules over large distances. Time zones simplify timekeeping by dividing the world into manageable segments, each with its own standardized time. This makes it easier for people to keep track of time and communicate with others over long distances, and it also helps to ensure that businesses and organizations can operate more efficiently.
