Where does Greenwich Mean Time (GMT) originate?

• A. Paris, France
• B. Greenwich, England
• C. New York, USA
• D. Tokyo, Japan

Answer: (B)

Greenwich Mean Time (GMT) originates from Greenwich, England, which is significant for its historical role in establishing the prime meridian—0 degrees longitude. The choice of Greenwich as the location for GMT was formally adopted during the International Meridian Conference held in 1884. At this conference, it was decided that the meridian passing through the Royal Observatory in Greenwich would serve as the reference point for universal timekeeping. This decision was driven by the need for a standardized time system for navigation and communication as international trade and travel increased. Consequently, GMT became a key reference, influencing time calculations around the world.
