Daylight savings time ends on Sunday
At 03:00 on Sunday morning, Europe switches from summer to winter time. This means an extra hour's sleep on Sunday morning as the clocks go back one hour. Winter time will last until 31 March 2024.
The current implementation of summer time dates back to 1977. Governments hoped to save energy by aligning sunlight hours more closely with people's lifestyles.
The system has many opponents, who point to the disruption of sleep that can cause short-term health problems. Studies have shown an increased risk of heart attacks, a rise in road accidents and an increase in cases of depression in the days following the start of summer time.
In 2018, the European Commission has proposed that the same time be used throughout the year. Crises such as the COVID-19 pandemic and the invasion of Ukraine put the issue on the back burner. In June 2021, the European Commission said that there would be no abolition of summer and winter time in the "coming years".
