About London Time
London uses Greenwich Mean Time (GMT, UTC+0) in winter and British Summer Time (BST, UTC+1) from the last Sunday in March to the last Sunday in October. London is the historical origin of the world's time system: the Prime Meridian at 0° longitude runs through Greenwich, and GMT was adopted as the global baseline when international railway and telegraph networks required synchronisation in the 19th century.
The London Stock Exchange opens at 8:00 AM GMT/BST, making London the first major Western financial market to open each day. London handles roughly 40% of global foreign exchange trading volume, giving its business hours outsized influence on currency markets. The 'London fix' at 4:00 PM GMT is the most widely referenced benchmark rate for FX transactions worldwide.
London's central position in the world timezone map — 5 hours ahead of New York and 9 hours behind Tokyo — means it has natural overlap with both the Americas and Asia. This geographical advantage has made London the world's largest international financial centre by cross-border activity.
