NEW YORK – While the end of daylight saving time offers the promise of an extra hour of sleep, it remains one of the least anticipated weekends on the American calendar.

A recent AP-NORC poll highlights that only 12% of American adults support the existing daylight saving time arrangement, which requires most states to adjust their clocks twice annually. In contrast, 47% of the population disapprove of this system, while 40% remain indifferent.

As clocks across the nation roll back one hour at 2 a.m. on Sunday, aligning with local time zones, the shift signals a return to standard time, bringing more morning daylight. However, findings from The Associated Press-NORC Center for Public Affairs Research indicate that many Americans find this transition unwelcome. If given a choice, the majority would opt to retain the extra hour of evening daylight instead.

Pranava Jayanti, a 31-year-old resident of Los Angeles, is among those who express strong opposition to the biannual clock change. Having grown up in India, where time remains constant throughout the year, he was cautioned by relatives about the adjustment when he moved to the U.S. for graduate studies.

Despite his preparations, Jayanti recalls being caught off guard by how swiftly darkness descended during the latter part of the day. “I thought I was ready, but the reality still surprised me,” he shared.

There have been calls for the U.S. to stop making the twice-yearly changes, including a piece of legislation that stalled after the Senate passed it in 2022. Among those urging that the country stick to one time for the entire year are the American Medical Association and American Academy of Sleep Medicine, as well as President Donald Trump, who issued a social media post about it earlier this year.

Permanent daylight saving (not daylight savings, as many people say colloquially) would be unpopular with a significant chunk of people, though, the poll found — particularly those who prefer mornings.

Changing the clocks is unpopular

The United States first started using the time shift over a century ago, during World War I, then again in World War II. Congress passed a law in 1966 that allowed states to decide if they would have it or not, but required their choices to be uniform across their territories. All states except Arizona and Hawaii make the time shifts; those two states remain on standard time year-round.

Time changes are also undertaken in some other parts of the world, like Canada and Europe, but not in others, like Asia. Europe and North America change the clocks a week apart, resulting in a short period where the time difference between the regions is an hour shorter than the rest of the year.

But although about half of U.S. adults are opposed to the switch — including 27% who are “strongly” opposed — many don’t care one way or another. That’s particularly true of adults under 30, with 51% saying they neither favor nor oppose the practice. Those over 30 are more likely to be opposed to it, with about half saying they dislike the twice-a-year switching of clocks.

If they had to choose one time for the country to use, more than half of adults — 56% – prefer making daylight saving time permanent, with less light in the morning and more light in the evening. About 4 in 10 prefer standard time, with more light in the morning and less in the evening.

Those who consider themselves “night people” are much more partial to permanent daylight saving time: 61% of them say this would be their choice.

“Morning people” were just about evenly split, with 49% of them preferring permanent daylight saving time, and 50% wanting permanent standard time.

Vicky Robson is one of those night people. If the 74-year-old retired nurse had to pick one time to go by, it would definitely be permanent daylight saving.

“I don’t get up early in the morning, so I don’t need the light in the mornings,” said Robson, of Albert Lea, Minnesota. “I need it more in the late afternoon, early evening. I like when it’s light later, because that’s when I do things. I’ve always worked the evening shift and now that I’m retired, I would go out and take a walk after supper if it was light.”

Why the clock change still happens

There’s no overwhelming evidence that daylight or standard time would be better for society, although there is advice for how to adjust sleep and habits to deal with it.

New research from Stanford University has found that at least when it comes to humans and our internal clocks — our circadian rhythm — having a single time would be better for health than switching. It also found that standard time had slightly better health benefits than daylight saving time.

“The more light you have earlier in the morning, the more robust your clock is,” said Jamie Zeitzer, one of the study authors and co-director of the Center for Sleep and Circadian Sciences at Stanford.

But that’s only one aspect, he added. There are a range of others, from economics to people’s personal preferences.

“This is something that people feel very passionate about, and their passion is usually driven by … themselves, what they would prefer,” he said. “There is no time policy that you can have that will make everyone happy.”

America did try once, in the mid-1970s, to switch to permanent daylight saving time. It was supposed to be a two-year experiment, but lasted less than a year because it was so unpopular.

At this point, the time shift and the resulting change in daylight hours in different seasons have become part of our culture, said Chad Orzel, professor of physics and astronomy at Union College and author of “A Brief History of Timekeeping.”

“People really like having the long evenings in the summer,” he said. But “we drop back in the fall so that we don’t have the thing that everybody hates, which is it being dark until after you get to work. … We have earlyish sunrises in the winter and late sunsets in the summer. We like both of those things. The price we pay for that is we have to change the clocks twice a year.”

The AP-NORC poll of 1,289 adults was conducted Oct. 9-13, using a sample drawn from NORC’s probability-based AmeriSpeak Panel, which is designed to be representative of the U.S. population. The margin of sampling error for adults overall is plus or minus 3.8 percentage points.
