As October and November arrive, an interesting tradition is observed in the United States—turning clocks back, known as the end of Daylight Saving Time (DST). This day is a bit confusing for many. Your smartphone automatically shows the time, but the clock on your wall may confuse you for a few days. This year, on Sunday, November 2, 2025, the “fall back” in the United States will occur, meaning clocks will be set back one hour. With this change, the weather will gradually cool, evenings will darken earlier, and many people will wonder—do we really need to change the time?

What Is Daylight Saving Time and Its History?

The main purpose of Daylight Saving Time (DST) is to make better use of the longer daylight hours in summer. It was first formally implemented in 1966 under the Uniform Time Act. Every year, clocks are set forward one hour on the second Sunday in March and back one hour on the first Sunday in November.
In 2025, DST began on March 9th and will end on November 2nd. The biggest benefit of this change is believed to be that people can enjoy more light on summer evenings, save energy, and have extra time for activities after work. However, the need for this tradition has been constantly debated.
The original idea behind DST was to save energy and increase efficiency. In earlier times, people could reduce candle and electricity consumption by making the most of natural light. But in today’s digital and 24/7 working age, this reason has become almost irrelevant.
An Hour of Sleep—A Blessing or a Problem?
The end of DST is a happy moment for many people because they get an extra hour of sleep. This is especially a relief for those with busy schedules.
But experts warn that this change affects the body’s circadian rhythm, the natural sleep-wake cycle. Shift workers, parents of young children, and the elderly may feel tired and lethargic for several days. According to the American Sleep Research Institute, the first few days of the time change increase the risk of road accidents, heart disease, and workplace errors.
In addition, many people experience effects on their physical and mental health. Problems like sleep deprivation, difficulty concentrating, and mood swings are common. Therefore, experts now recommend that the time change be permanently abolished and the time once set should be adhered to.
Growing Controversy and Political Debate Over DST
The debate over the usefulness of DST resurfaces every few years.
Former President Donald Trump wrote in April 2025 that “DST should be made permanent because changing the clocks twice a year is inconvenient and expensive.” However, in December 2024, he stated the opposite, saying that DST should be completely abolished and Standard Time should be made permanent.
This makes it clear that DST isn’t just a time change but also a matter of political perspectives and social preferences. Some people want more light during the long summer evenings, while others value brighter morning light so that children and office-goers don’t have to go out in the dark.
Time Reform and the Stalled Issue in Congress
The debate over DST isn’t limited to the public and experts. It has been discussed in Congress for several years, but no concrete results have emerged. The Sunshine Protection Act was passed in 2022, aiming to make DST permanent in the United States. However, the bill stalled in the House and failed to become law.
It was reintroduced in 2025, but no concrete progress was made. Several states are taking initiatives to change their own.
Pennsylvania and Other States’ Initiatives
Pennsylvania passed a resolution in March 2025 urging Congress to end this “outdated tradition.” Over the past few years, more than 29 states have introduced similar resolutions. However, any state requires federal approval to officially make a permanent change.
Some states and territories that do not observe DST include Hawaii, most of Arizona, Puerto Rico, Guam, American Samoa, and the U.S. Virgin Islands and the Northern Mariana Islands.
What will happen on November 2, 2025?
On Sunday, November 2, at 2 a.m., clocks will be set back one hour to 1 a.m. This means that mornings will be brighter than before, but evenings will get darker earlier.
Many will consider this a time of rest, while others will find it a disturbing change. Furthermore, the season will gradually move toward winter. The sun will set earlier, temperatures will drop, and days will seem shorter.
Is Daylight Saving Time no longer necessary?
DST was introduced to save energy and maximize the use of daylight. But its importance has diminished in the modern era.
Studies show that DST now only results in less than 1% energy savings. On the contrary, it negatively impacts sleep, mental health, work efficiency, and road safety.
Will this tradition ever end?
The debate over DST continues, but no final decision has yet been made. Political differences and a slow process in Congress are holding it back.
Until new legislation is passed, Americans will have to change clocks twice a year—forward in March and back in November.
Conclusion: An extra hour of sleep and a new debate
DST is returning in 2025. You’ll definitely get an extra hour of sleep, but with it will come a renewed debate—is there a need to change clocks every year?
This year, as you set your clocks back, you might wonder—do we need to change the time or should we stick to a permanent time? This tradition has been around for a long time, but now is the time to seriously consider its pros and cons.
