Origins of Time Zones

The concept of time zones was introduced in the late 19th century as a solution to the chaos caused by each city keeping its own local time. The advent of railroads and telecommunications necessitated a standardized timekeeping system. Sir Sandford Fleming, a Canadian railway planner and engineer, proposed the division of the world into 24 time zones, each one hour apart. The proposal was adopted at the International Meridian Conference in 1884, held in Washington, D.C. This standardization aimed to improve scheduling and coordination across different regions, especially for international travel and communication.

Before the establishment of time zones, each location set its time based on the position of the sun, leading to significant discrepancies. The introduction of time zones provided a structured framework, allowing for a more synchronized global society. The Prime Meridian, set at Greenwich, England, serves as the starting point for calculating time zones, known as Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC). Today, time zones are an integral part of our daily lives, providing consistency in activities such as work, travel, and communication.
