Does DST Actually Save Energy?
This was the original justification, and it is the claim that has held up worst. A US Department of Energy report to Congress in 2008 measured the four weeks added to DST in 2007 and found a saving of about 0.5% of daily national electricity use — real, but small.
Other work has found no saving at all. A well-known study of Indiana, which adopted DST statewide in 2006, found residential electricity use actually rose by 1–4%: households used less lighting but more air conditioning on hot summer evenings. Any lighting savings are also partly offset by extra petrol use as people travel more in the lighter evenings.
Getting ready
- Use the extra evening daylight in summer for outdoor activities and vitamin D.
- Check and replace smoke detector batteries when changing clocks - it's a good reminder!
- Be extra cautious driving the Monday after the spring time change - accident rates increase.
- Use the phrase 'Spring forward, fall back' to remember which direction to change your clocks.
Frequently asked questions
When do the clocks change in Denmark in 2025?
Clocks go forward on Sunday, March 30, 2025 and back on Sunday, October 26, 2025.
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.
