D(caps)aylight saving time (DST) for 2025 officially ends this Sunday, November 2. It’s that time of the year again when clocks “fall back” by one hour, giving everyone an extra hour of sleep. Here’s a simple guide to understand what’s happening, why it exists, and who follows it.
When Does the Time Change in 2025?
Daylight saving time will end at 2 a.m. on Sunday, November 2, 2025. At that moment, clocks will turn back to 1 a.m., meaning the same hour will repeat once more.
Daylight saving time started earlier this year on March 9, 2025, and will return again on March 8, 2026, when clocks “spring forward” by one hour.
Do We Gain or Lose an Hour?
When daylight saving time ends, we gain one extra hour. For most Americans, that means one more hour of sleep on Sunday morning.
Most digital devices such as smartphones and computers update automatically, but traditional clocks, watches, and wall clocks may need to be reset manually.
After the change, the sun will rise and set earlier, so you’ll notice it getting darker in the evening much sooner than before.
Why Do We Change the Clocks?
The idea of daylight saving time has been around for over a century. While many believe it started to help farmers, that’s actually a myth.
Daylight saving was first used in Germany in 1916 during World War I as a way to save energy by using more daylight and less artificial light. Soon after, other European nations and the United States adopted the same system.
In America, the Uniform Time Act of 1966 made daylight saving time a national standard, as recorded by the U.S. Bureau of Transportation Statistics.
Which States Don’t Follow Daylight Saving Time?
Most of the United States observes daylight saving time, but Hawaii and most of Arizona (except the Navajo Nation) do not.
Several U.S. territories also skip the time change, including:
- American Samoa
- Guam
- Puerto Rico
- The U.S. Virgin Islands
- The Northern Mariana Islands
While states are allowed to opt out of daylight saving time, they cannot choose to stay permanently on daylight saving hours without federal approval.
Globally, most countries don’t observe DST at all. The U.S. and much of Europe are among the few that still do, according to Pew Research Center.
Many other countries that observe DST rolled their clocks back in October 2025, as per TimeandDate.com.
The Debate Over Daylight Saving Time
Daylight saving time has been a topic of debate for many years. In a 2022 CBS News/YouGov poll, nearly 80% of Americans said they wanted to end the current clock-changing system.
In the same year, the U.S. Senate passed the Sunshine Protection Act, which aimed to make daylight saving time permanent. However, the bill didn’t pass in the House of Representatives.
Former President Donald Trump, before his return to office, also voiced his opinion on Truth Social, calling daylight saving time “inconvenient and costly” and suggesting that the U.S. should eliminate the twice-a-year clock change.
Interestingly, in the past, Trump had also shown support for keeping permanent daylight saving time, meaning clocks would stay one hour ahead all year.
Health Effects of Changing the Clocks
Medical researchers have found that switching clocks twice a year may have negative effects on health. Studies from Stanford Medicine suggest that these time changes can disrupt sleep and may contribute to a higher risk of heart attacks, strokes, obesity, and mood changes.
The sudden shift in daylight can affect your body’s internal clock, or circadian rhythm, leading to fatigue and temporary mood swings in some people.
Key Takeaway
So, remember — at 2 a.m. on Sunday, November 2, 2025, set your clocks back by one hour. You’ll gain an hour of sleep, but evenings will get darker earlier. Whether you love the extra morning light or dislike the early sunsets, daylight saving time remains a part of American life — at least for now.
