What would “no more clock changes” do to your mornings?

Everyone says they want to stop changing the clocks. Nobody agrees which hour to keep. Pick a city and see a full year of sunrises and sunsets — starting tonight — under three rules.

Why this is a live argument in 2026

The US House passed the Sunshine Protection Act on 14 July 2026, which would put most of the country on permanent daylight saving time. It still needs the Senate and a signature — and, as reported in October, unless that happens before 1 November, Americans fall back as usual.

Europe has been stuck since 2018, when an EU consultation drew 4.6 million responses and 84% wanted to stop changing the clocks. The Commission proposed ending the switch; member states never agreed on which time to keep.

Both sides have tried it

Britain ran year-round GMT+1 from 1968 to 1971 (the “British Standard Time” experiment). Scotland hated the dark mornings, and MPs voted 366 to 81 to end it.

The US went to permanent daylight time in January 1974. On 7 January the sun rose at 8:27 AM in Washington; support fell from as high as 74% to about 30% within weeks, and it was repealed that autumn. Sleep-medicine groups such as the American Academy of Sleep Medicine argue for permanent standard time instead.
