When and why do the clocks go forward?

The transition to British Summer Time occurs on Sunday, when clocks will advance by one hour. This change signifies the approach of warmer weather and extended daylight hours. The shift, often referred to as “springing forward,” moves the clocks from 1:00 AM to 2:00 AM. This annual adjustment is designed to maximize daylight during the evening throughout the spring and summer months. The practice is observed across many countries in Europe and North America, aiming to align waking hours with daylight. As a consequence, mornings will become darker for a period, but the benefit is the addition of an hour of daylight in the evening, which many associate with increased outdoor activity and a general sense of improved well-being. This change officially heralds the start of a period of longer days.
