🕰️ UK Timezones Explained

The UK uses a single timezone: Europe/London. In winter (late Oct–late Mar): GMT (UTC+0). In summer (late Mar–late Oct): BST (UTC+1). The Channel Islands and Isle of Man also observe Europe/London. Northern Ireland, Scotland, Wales and England all share the same time.

📍 Greenwich Mean Time (GMT)

GMT originates at the Royal Observatory, Greenwich, London. Since the International Meridian Conference of 1884, Greenwich has been the world's prime meridian (0°). GMT is used for aviation, shipping, weather systems, and all international time coordination.

☀️ British Summer Time (BST)

BST (UTC+1) runs annually from the last Sunday of March to the last Sunday of October. Clocks "spring forward" 1 hour in March and "fall back" in October. BST has been observed since the Summer Time Act of 1916, conceived by builder William Willett to save coal during WWI.
