End of watch movement in the United States. Americans will stay permanently at daylight saving time

Posted by

Last Tuesday, the US Senate unanimously passed a bill that removes the need to move the watch hands back and forth one hour twice a year. Unlike in Europe, where individual states have failed to agree on whether to use daylight saving time or Central European time, the US has a clear picture: will remain permanently in daylight saving timepresents the Ars Technica website.

The one-page “Sunshine Protection Act”, tabled by Senators Marc Rubio and Sheldon Whitehouse, is approved for a vote in the House of Representatives. The bill, originally tabled in 2018 and re-tabled last year in 2021, would repeal the Calder Act, which in 1918 introduced a time change twice a year.

Permanent summer time since 2023

As a result, the change would mean that the people of the United States they will switch to daylight saving time for the last time in the spring of next year. From a political point of view, it is not clear whether any of the big parties will create a serious opposition to a possible vote in the House of Representatives. President Joe Biden has not yet announced his position on the bill.

The United States adopted daylight saving time after it was introduced in 1916 by a number of European countries, notably Germany and Austria, as a means of saving energy during World War I. However, daylight saving time was historically inconsistent in the United States, even after the adoption of the Single Time Act in 1966. Later laws updated the exact time frame for “standard” and “saving” time changes.

In the following decades, people around the world discussed changes over time, and in 2019, thanks to a successful vote in its parliament, the European Union was on the verge of complete abolition of summer time. However, its original goal of ending it in 2021 required the cooperation of committees that postponed the process. It is not clear whether and how the EU’s vote in favor of ending daylight saving time will turn out.

The originally stated purpose of summer time, ie to save energy according to how much sunlight is available at a given time of year, has proved to be less clear in the modern electricity-driven world, based on data collected from energy companies. The US Department of Energy estimated in 2008 that extending daylight saving time by three weeks resulted in negligible electricity savings of only 0.03%.

Several scientific studies have examined how the number of accidents would change if the United States stopped changing times. A 2004 study by the US National Institutes of Health concluded that termination would lead to a statistically significant reduction in the number of deaths both for car passengers and pedestrians.

Republican Sen. Marco Rubio, the bill, said on Tuesday that persistent summer time would help prevent pedestrian accidents, reduce crime, seasonal depression and childhood obesity. “Moving time back and forth every year only creates unnecessary confusion and harms the health of Americans and our economy.” Democratic Sen. Ron Wyden said last year.

Of course, there have also been debates in the US, whether it is better to stay at standard or summer time. The American Academy of Sleep Medicine has previously argued the opposite, and said in a 2020 study that public health and safety would benefit from the abolition of daylight saving time and the maintenance of standard time.

“A steady, year-round standard time is the ideal choice that best suits our circadian sleep and wake cycle,” said the main author of the study, M. Adeel Rishi. “Summer time results in more darkness in the morning and more light in the evening, which disrupts the body’s natural rhythm.”
