A Brief History of Timezones
The concept of time zones emerged in the 19th century with the expansion of railroads and telegraph networks. Before this, each city kept its own local time based on the sun's position. The need for standardized time became crucial for scheduling trains and coordinating telegraph messages.
In 1884, the International Meridian Conference established the Prime Meridian in Greenwich, England, and divided the world into 24 time zones, each 15 degrees of longitude apart. This system, known as Coordinated Universal Time (UTC), became the foundation for modern timekeeping worldwide.
