Summary (tl;dr)

Clocks in the United Kingdom and most of Europe are "falling back" by an hour today, October 25, 2026, marking the end of daylight saving time for the region. Most of the U.S. and Canada will follow suit next week, on November 1, 2026.

Essential Background

Daylight Saving Time (DST), often referred to as "Summer Time" in many parts of the world, is the practice of adjusting clocks forward during warmer months, typically by one hour, to ensure daylight extends later into the evening. This system was largely adopted during World War I with the primary aim of conserving energy and fuel by maximizing the use of natural daylight and reducing the need for artificial lighting in the evenings.

The Full Story

Today, October 25, 2026, marks the end of daylight saving time across the United Kingdom and the majority of European countries. Clocks in these regions will "fall back" by one hour, typically at 2:00 AM local time in the UK (returning to 1:00 AM, Greenwich Mean Time) and at 3:00 AM Central European Summer Time (CEST) in many continental European nations (returning to 2:00 AM Central European Time, CET). This adjustment grants an extra hour of sleep for many. Meanwhile, most of the United States and Canada will observe their "fall back" a week later, on Sunday, November 1, 2026. At 2:00 AM local time, clocks will be reset to 1:00 AM. This staggered change results in a temporary, unusual one-hour difference in time across the Atlantic between Europe and North America.

Why It Matters

The biannual clock change consistently sparks widespread public discussion and debate. While some argue that daylight saving time offers benefits such as more evening daylight for activities and potential energy savings, these advantages are often contested. Critics frequently highlight the disruptions to sleep patterns and potential negative health consequences, including increased risks of heart attacks, strokes, and traffic accidents in the days following the time shifts. In Europe, there's significant public sentiment against the practice, with an EU-wide consultation in 2018 showing 84% support for abolishing the clock changes; the European Parliament voted in 2019 to end it, but member states have yet to reach a consensus on a permanent time regime, stalling the legislation. In the United States, the House of Representatives passed the "Sunshine Protection Act" in July 2026, aiming to make daylight saving time permanent; however, the bill has not yet passed the Senate, meaning the upcoming November 1st time change will proceed as scheduled. Sleep experts largely advocate for permanent standard time, citing its better alignment with natural human circadian rhythms.
