Is Daylight Saving Time Ending Permanently? What We Know So Far

Where the Legislation Stands

The most common question people have when clock-changing season arrives is whether this will be the last time. The short answer: probably not yet.

In March 2022, the U.S. Senate passed the Sunshine Protection Act by unanimous consent, which would have made daylight saving time the permanent, year-round standard across the country. It was the furthest Congress had gone toward ending the twice-yearly clock change since the practice was standardized in 1966. The bill never received a House vote, and it died when that congressional session ended.

As of April 2026, the legislation has not been reintroduced. No new bill to make DST permanent, or to make standard time permanent, has moved through either chamber. The bipartisan appetite that seemed to exist in 2022 has not translated into renewed action, and the status quo remains: clocks still change twice a year, in March and November.

This is not for lack of public support. Surveys consistently show that a large majority of Americans want to stop changing the clocks. Agreement on that much is easy. Agreement on which time to keep permanently is harder.

What States Have Done (and Why It Hasn't Mattered)

In the absence of federal action, many states have taken their own approach. Since 2018, more than 19 states have passed legislation to observe daylight saving time year-round. The list includes Florida, which passed the Sunshine State Act in 2018, as well as Georgia, Tennessee, Alabama, and several others.

None of these laws is in effect.

Federal law under the Uniform Time Act of 1966 controls how states can handle time. States are legally permitted to opt out of daylight saving time entirely and remain on standard time year-round, as Arizona and Hawaii do. But states are not allowed to adopt permanent daylight saving time without federal authorization. States that have passed these laws are essentially waiting for Congress to act first.

This creates an odd situation: dozens of state legislatures have voted to end the clock change, but they are legally powerless to implement it. The political will exists at the state level. The federal legislation that would unlock it does not.

The Real Debate: Which Time Should Be Permanent?

Assuming Congress eventually acts, the clock change would end in one of two ways: permanent daylight saving time or permanent standard time. These are not equivalent in their health effects, and the scientific community has a clear preference.

The Case for Permanent Standard Time

Standard time is the time your location observes in winter, when clocks are not shifted forward. Under standard time, the sun rises earlier by clock time, so morning light arrives when most people are waking up.

Morning light is the most powerful cue for the human circadian system. Exposure to bright light within the first hour after waking suppresses melatonin, appropriately raises cortisol, and signals the brain that the day has begun. This is what regulates sleep timing, mood stability, and alertness throughout the day.

The American Academy of Sleep Medicine, along with multiple other sleep and circadian science organizations, has formally endorsed permanent standard time. Their position is that permanent DST would move morning light to even later times, misaligning the body clock with social schedules in ways that could worsen insomnia, metabolic health, and mood disorders.

There are also school safety concerns. Under permanent DST, children in northern states would be waiting for school buses in full darkness for months during winter, because sunrise would not occur until 8:30 or 9:00 a.m. in some cities.

The Case for Permanent DST

Advocates for keeping daylight saving time year-round focus on the benefits of evening light. Permanent DST means an extra hour of usable evening daylight, which supporters argue encourages outdoor activity, reduces crime in the hours after work, and supports small businesses and recreational industries that depend on evening foot traffic.

The Sunshine Protection Act was named for these benefits. The senators who pushed for it emphasized that people use the extra evening hour in ways that benefit public health and the economy.

What this argument tends to underweight is the circadian biology. The body cannot be fooled into treating evening light as morning light. Later sunrises do not satisfy the morning-light signal the circadian system needs, regardless of how pleasant the evenings become.

What the International Experience Shows

The United States is not alone in debating this. The European Union voted in 2019 to end seasonal clock changes, with member states given the choice of which time to adopt permanently. More than five years later, the policy has not been implemented because EU member states cannot agree on whether to adopt permanent summer time (equivalent to DST) or permanent winter time (equivalent to standard time).

The concern driving EU inaction is fragmentation. If neighboring countries use different time zones, it disrupts trade, travel, and communication across borders. Germany on permanent summer time and France on permanent winter time would create a one-hour mismatch that did not exist before.

This is a smaller-scale version of the same coordination problem the U.S. faces, though within a single country, the coordination issue is easier to resolve. Still, the EU experience is a useful reminder that broad agreement on ending the clock change does not automatically produce agreement on which clock to keep.

Russia offers another data point. The country switched to year-round DST in 2011, with the idea that more evening light would be popular. Within a few years, research documented increases in depression, fatigue, and cardiovascular complaints during dark winter mornings. Russia reversed course in 2014 and returned to permanent standard time.

What Would Change for Daily Life

If the U.S. adopted permanent standard time, most Americans would notice little change during the summer months. The main shift would come in fall and winter, when clocks would no longer spring forward, and evenings would get dark earlier than they currently do under DST. Sunrise would remain comfortably early year-round.

If the U.S. adopted permanent DST, summers would feel similar to today. The significant change would come in winter. Sunrise would shift dramatically later. In cities at higher latitudes, like Chicago, Detroit, and Seattle, winter sunrises under permanent DST would not occur until 9:00 a.m. or later. Anyone commuting to a morning job or sending children to school in those cities would be doing so in complete darkness for months.

Developing healthy sleep habits is harder when morning darkness persists well into typical waking hours. The practical impact on daily life under permanent DST would extend beyond schedule preferences. It would affect how easily people sleep, how alert they feel during the day, and potentially how their mood and metabolic health hold up across a long dark winter.

What Is Likely to Happen

Congressional action on this issue is unpredictable. There is genuine public demand for ending the clock change. There are states waiting for authorization to act. The Senate has shown it can pass something on this topic. But the House has not yet moved, and the legislative calendar is always crowded.

The most likely near-term scenario is that clock changes continue as usual while the political conversation continues to build. Whether that momentum eventually produces a permanent standard depends on congressional priorities that are hard to predict.

If federal law changes, states that have already passed permanent DST laws would likely move quickly. States that have not acted could observe a patchwork period in which different states behave differently, especially if federal law allows optionality rather than mandating a single outcome.

The Bottom Line

The debate over ending daylight saving time is real, and the political momentum is genuine, but it has not yet produced a law. Congress would need to act before any state-level legislation could take effect. When that happens, the choice between permanent standard time and permanent DST will matter for health. The scientific evidence clearly points to standard time as the healthier option, but the legislative outcome remains uncertain.
