1. Understanding Time Zones

Time zones are longitudinal divisions of the Earth that share the same standard time. This system helps coordinate activities across different geographic locations. Before the implementation of standardized time zones, each locality often kept its own time, based on the position of the sun. This led to significant confusion in transportation and communication, especially with the advent of railways and telegraphs.

Historical Context: The concept of standard time zones was first proposed by Scottish-Canadian railway engineer Sir Sandford Fleming in the late 19th century. He advocated for a worldwide system of 24 time zones, each spanning 15 degrees of longitude.
Global Implementation: The International Meridian Conference in 1884 officially adopted the concept of standard time zones, with Greenwich, England, established as the Prime Meridian (0 degrees longitude). This set the foundation for the global timekeeping system we use today.
Impact on Daily Life: Time zones directly impact various aspects of our lives, including scheduling meetings, coordinating travel, and understanding television broadcasts. They also affect international business, trade, and global communications.
