From Big Ben in London to the Corpus Chronophage in Cambridge, the UK has some of the world’s most famous and interesting clocks. We were one of the first countries to standardise time throughout a region (what we know as Greenwich Mean Time or GMT) and we’re one of several countries in the world to change the clocks according to the seasons.
Daylight saving time allows us to enjoy more daylight hours during summer and winter. In summer, we score an extra hour of light in the evenings, and in winter, sunrise arrives earlier. Clocks go forward an hour at 1am on the last Sunday in March, and back an hour at 2am on the last Sunday in October.
