What Time Is It in London Right Now?
What Time Zone Does London Use?
London follows Greenwich Mean Time (GMT), which corresponds to UTC+0 during the winter months. Because the Prime Meridian runs through Greenwich in London, the city has historically served as the global reference point for world time. GMT is widely used as the baseline for calculating time differences between countries and international time zones.
Does London Use Daylight Saving Time?
Yes. London observes Daylight Saving Time, known locally as British Summer Time (BST). Clocks move forward by one hour in late March, shifting from GMT (UTC+0) to BST (UTC+1). The clocks are then set back one hour in late October when the UK returns to Greenwich Mean Time for the winter season.
