Economic Impact of DST in Europe
The economic effects of Daylight Saving Time in Europe are real but modest, and studies disagree on their size. Retailers and hospitality businesses generally favour DST, arguing that lighter evenings encourage shopping, dining out and other after-work spending — the US retail lobby was one of the main forces behind the 2005 extension of the DST period.
The transitions themselves carry a cost. Research from Chmura Economics has put the one-off economic cost of the spring change in the United States at roughly $430 million a year, driven by lost productivity, workplace injuries and the health effects of a disrupted night's sleep.
Health Considerations for Europe Residents
The spring transition is the one that hurts. A study in Open Heart found the risk of heart attack rose by about 24% on the Monday after clocks went forward, before falling back to normal within the week. Research published in Current Biology found a 6% rise in fatal traffic accidents in the week following the spring change, with the effect strongest in the morning and in the western parts of time zones.
The autumn change, when most people gain an hour, shows no comparable spike. Researchers attribute the difference to sleep loss rather than to the clock change itself.
Agricultural Considerations
The story that DST was introduced for farmers has it exactly backwards. Farmers in Europe and elsewhere were among its most persistent opponents, and the American farm lobby successfully campaigned to have national DST repealed after the First World War.
The reason is straightforward: farm work follows the sun, not the clock. Moving the clock forward just means doing the same work an hour earlier by the clock, while deliveries, markets and hired labour all shift with it. Dairy farmers make the point most often, since cows keep to their own schedule and take several days to adjust to a changed milking time.
Getting ready
- Gradually adjust your sleep schedule a few days before the time change to minimize disruption.
- Update your car clock, microwave, and other manual clocks that don't auto-update.
- Take advantage of the 'extra' hour in fall to catch up on sleep or tackle a project.
- Check and replace smoke detector batteries when changing clocks - it's a good reminder!
Frequently asked questions
When do the clocks change in Europe in 2024?
Clocks go forward on Sunday, March 31, 2024 and back on Sunday, October 27, 2024.
Which way do the clocks go?
"Spring forward, fall back" is the usual mnemonic: forward one hour in spring, back one hour in autumn.
Do I have to change anything myself?
Phones, computers and anything that syncs over the internet update on their own. Car clocks, ovens, microwaves and older wall clocks generally do not.
Is Daylight Saving Time being scrapped?
It has been proposed in many places and adopted in few. The European Parliament voted in 2019 to end mandatory clock changes and the change has stalled; in the United States the Sunshine Protection Act has repeatedly passed the Senate without becoming law. Most of the world that changes its clocks is still changing them.
