The exact date clocks go back this month in the UK and why

UK clocks go back this month as the country moves out of summer time, giving people an extra hour on Sunday night into Monday morning. In the autumn change, clocks will be set back at 2.00am on the final Sunday of October—this year, Sunday, October 25. The shift is intended to maximize daylight during the darker months. For most households, devices connected to the internet—smartphones, televisions, laptops and tablets—update automatically. However, users still need to adjust non-internet devices such as alarm clocks and car radios. The UK’s clock-change system, called BST during the summer period, has been in place since 1971, building on an earlier 1916 energy-saving initiative in Germany.
