WASHINGTON — Daylight saving time ends Sunday, Nov. 5, rolling back the clocks an hour in the middle of the night and granting most Americans an extra hour of sleep as they "fall back."
Only two U.S. states, Arizona and Hawaii, don't observe daylight saving time at all, refusing to roll their clocks forward and backward every year. But Hawaii and Arizona are outliers, relying on a loophole in a 57-year-old federal law that requires states to stay on daylight saving time.
That's right, Congress decides if we can have that extra hour of sleep.
The Uniform Time Act of 1966 mandates the country use daylight saving time, but allows states to opt out and exempt themselves from the practice to stay on standard time year-round. It does not allow states to permanently establish daylight saving time, which would keep them an hour ahead from November to March while other states switch to standard time.
Many states have passed measures to stay on daylight saving time permanently — a move that some have called "lock the clock." For some states, they're willing to go forward with it as long as a few of their neighbors do the same.
In the last five years, 19 states have passed legislation or resolutions supporting year-round daylight saving time, according to the National Conference of State Legislatures. In 2023, at least 29 states considered or are considering legislation related to daylight saving time.
There's even been a suggestion that some states leave the eastern time zone entirely and adopt a new one used by parts of Canada and a couple U.S. territories.
But none of those bills or laws can take effect until there is a federal appeal of the congressional act. In essence, Congress needs to repeal the law in order for the U.S. to stop using daylight saving time.
There have been efforts on the congressional level to make this change.
For the past few years, Sen. Marco Rubio of Florida has introduced a version of what he calls the "Sunshine Protection Act" which would permanently establish daylight saving time for the whole country. The bills, however, usually die before they ever come close to becoming law.
Back in 2022, the U.S. Senate passed a version of that bill but it was never voted on by the House of Representatives.
With little to no progress made on the 2023 measure, Americans will continue to "spring forward" and "fall back" in 2024.
Here is where each state stands in the effort to move to daylight saving time all year long, though Congress would need to act before states that have enacted laws can make the change.
Alabama
In May 2021, Alabama passed an act that would have the state permanently observe daylight saving time. That bill is still waiting on a federal appeal of the Uniform Time Act of 1966 to take effect.
Alaska
State Rep. Dan Ortiz introduced House Bill 31 in Feb. 2021 to recognize daylight saving year-round if Congress makes the move by 2030. The bill has been stalled in the state legislature since May 2022.
Even if it did pass, Alaska might not see the benefits other states could from ending daylight saving time. According to Alaska Public Media, it could make winters darker in the northernmost U.S. state.
“Nome would have a sunrise after 1pm,” Brian Brettschneider, a climatologist in Anchorage, told APM.
Arizona
Arizona is one of the more well-known examples of states not following daylight saving time. Instead, the state observes Mountain Standard Time year-round. But the Navajo Nation, which is partially in Arizona, does observe DST.
That means from May to November every year, Navajo Nation is an hour ahead of the rest of the state of Arizona.
Arkansas
In Dec. 2022, State Rep. Johnny Rye introduced a bill to the Arkansas House which would adopt year-round DST. But on Jan. 9, 2023, he withdrew the bill and recommended its effects be studied by a committee on governmental affairs.
Rye tried to pass a similar bill in 2020. That bill passed the House 71-24 and made it to the Senate committee of State Agencies and Government Affairs, but it failed to pass during the legislative session.
In March 2023, State Rep, Stephen Meeks introduced a bill to the Arkansas House to adopt standard time year round, eliminating daylight saving time. The effort failed in the House.
California
In 2018, voters approved a proposition allowing the state legislature to pass legislation that would put California on permanent DST. Several legislators, most recently California Assembly member Steven Choi, have attempted to pass such a bill. But each time, the legislation has either been pulled or has died in committee.
Colorado
Colorado is another state waiting on the federal government to enact permanent DST. In 2022, after years of failed attempts, the Colorado House unanimously passed a bipartisan bill that would make daylight saving permanent once the Uniform Time Act of 1966 is repealed.
Connecticut
Two bills in 2021 were introduced into the state legislature, both of which would have had Connecticut adopt Atlantic Standard Time (AST), dropping DST similarly to Arizona or Hawaii. But neither bill made it to a vote, leaving any time-related legislation in limbo.
Atlantic Standard Time, which is used in the U.S. territories of Puerto Rico and the U.S. Virgin Islands, is one hour ahead of Eastern Standard Time.
There were similar efforts in 2023 but all bills failed.
Delaware
In 2019, Delaware passed a bill for the state to permanently remain on daylight saving time, but it was contingent on Pennsylvania, New Jersey and Maryland doing the same.
As with other bills of this nature, it would also depend on congressional action allowing states to permanently adopt DST.
Florida
Florida became the first state to pass a resolution to observe daylight saving time year-round, passing the legislation in 2018.
If Congress repeals the Uniform Time Act of 1966, it would go into effect immediately.
Georgia
In 2021, Georgia's legislature passed a permanent daylight saving time law that was signed by Gov. Brian Kemp.
Congress must repeal the Uniform Time Act of 1966 for Georgia's bill to take effect.
Hawaii
Hawaii, like Arizona, doesn’t observe daylight saving time. Federal law permits states to opt out of daylight saving but does not allow them to observe it year-round.
In 2011, a bill was introduced to the Hawaii House that would have the state opt-in, but it never passed.
Idaho
Idaho is a complicated case because it is divided among two time zones (Pacific Time for the northern half of the state and Mountain Time for the south). In 2020, the Idaho legislature passed a measure which would make DST permanent in the northern half of the state — but not the southern half — if the state of Washington also makes the permanent switch.
Illinois
One bill introduced into the Illinois House of Representatives seeks to make daylight saving time year-round. The HB 1192 is still pending.
At least seven bills were introduced in the Illinois House in 2021 regarding daylight saving time. But none of these bills has ever made it past the state legislature. When the legislature's most recent session ended on Jan. 10, 2023, those bills died without getting a vote.
Indiana
Indiana is another state split between two time zones. While the majority of counties in Indiana are in the Eastern time zone, 18 counties in the northwest and southwest parts of the state are in the Central time zone. The Indiana General Assembly's website shows no pending legislation in their current session related to daylight saving time.
Iowa
The Iowa Legislature introduced two bills in 2023 that would make daylight saving time permanent. The two bills are currently pending-carryover, according to the National Conference of State Legislatures.
But even if HF 242 and HB 498 get a vote and are signed into law, it wouldn't take effect until there's federal approval.
Kansas
The last time Kansas lawmakers put forward a daylight saving time bill was in 2019. That bill would have kept the state off of DST, but it died in 2020. If it had passed, that bill would have taken effect without congressional approval, because states are able to stop using DST, but aren't able to adopt it permanently without congressional action.
Kansas lawmakers have also proposed moving to daylight saving time year-round, but those proposals have failed to get a voted by the state legislature.
Kentucky
Kentucky's House of Representatives passed a resolution in 2020 that would make DST permanent for the state. But that appears to have been the end of the line for the bill, which didn't make it into law that year.
In 2023, the Kentucky House introduced a measure to make DST permanent if the Uniform Time Act of 1966 or the Standard Time Act of 1918 are amended by Congress to allow year-round daylight saving time.
Louisiana
House Bill 132, making daylight saving time permanent in Louisiana, was signed into law in 2020. Like other permanent DST laws across the nation, it cannot go into effect while Congress keeps the Uniform Time Act of 1966 in place.
Maine
In 2019, Maine enacted a law to stay on Eastern Daylight Time all year long, but only if Congress acts to allow it. In 2021, Maine commissioned a study on the topic.
Maryland
House Bill 165 sought to make DST permanent year-round but ultimately died in the House. A similar Senate bill was filed this year but also failed.
Maryland has had similar efforts before but they have never been able to become law. Maryland House Bill 1013, which would have done away with DST for the state, passed the House in 2021, but stalled in a Senate committee. A separate but similar Senate bill, SB 840, was also introduced in 2021 and ended up stalled in the same committee.
Massachusetts
Massachusetts introduced a pair of concurrent bills that are pending in the House and the Senate, which would repeal DST and put the state exclusively on Atlantic Standard Time. If passed in both chambers and signed into law by the governor, the change could take effect without Congress.
Michigan
A 2023 Senate bill, pending in the Michigan Senate, would adopt daylight saving time year-round as long as Congress allows the switch.
Michigan's House of Representatives passed a bill in April 2021 to move to year-round daylight saving time as long as Wisconsin, Illinois, Indiana, Ohio and Pennsylvania also made the switch. The Michigan bill was sent to the Senate, where it died in committee.
Minnesota
A pair of bills in the Minnesota House and Senate are currently "pending-carryover" according to the NCSL. The bills would recognize federal standard time year-round beginning in 2024.
The Minnesota legislature approved a plan in 2021 to permanently observe daylight saving time, pending congressional approval.
Mississippi
Mississippi lawmakers passed legislation in 2021 for year-round daylight saving time, pending congressional approval.
Missouri
In 2021, lawmakers in Missouri proposed a bill that would permanently put the state at daylight saving time, if three of eight bordering states follow suit. The Missouri House approved the plan, but the state Senate failed to vote on the measure before the session ended.
In 2023, there were two House bills under consideration that would make DST permanent. House Bill 157 and House Bill 265 both failed to become law.
Montana
A bill in the Montana House attempted to create state standard time, declaring the Montana exempt from daylight saving time. However, the bill failed to become law.
Montana passed and signed into law in May 2021 a measure to keep the state in daylight saving time year-round if Congress or the U.S. Department of Transportation approves. Three of these states must also go on full-year daylight saving first: Idaho, North Dakota, South Dakota, Utah or Wyoming.
Nebraska
A bill under consideration in the Nebraska legislature would move the state to daylight saving time year-round if three neighboring states also made the move. Wyoming and Colorado already have such legislation in place.
The plan would still require Congress to allow the time change before taking effect.
Nevada
Nevada's has a bill "pending-carryover "according to NCSL. The bill is aimed at changing making daylight saving time permanent all year long.
The last bill to approach the subject was in 2021, and would have directed the state to adopt either Pacific Daylight Time or Pacific Standard Time year-round — depending on what California does — to keep time zones standardized throughout the region. But the bill died before a vote.
New Hampshire
In 2021, a New Hampshire lawmaker filed a bill that would move the state to Atlantic Standard Time — similar to Connecticut's proposal — permanently. But that bill failed, and there is no current legislation on the table that would repeal or adopt permanent DST for the state.
New Jersey
A 2023 bill by New Jersey lawmakers in the State Senate was put forward that would put the state on daylight saving time permanently if Congress gives its approval. But that measure is still pending in the legislature.
New Mexico
A pair of New Mexico state senators put forward a bill in the 2023 legislative session that would exempt the state from daylight saving time like Arizona or Hawaii. But the bill ultimately failed in the Senate.
New York
New York introduced seven bills into the senate and state assembly regarding daylight saving time. The efforts range from making DST permanent year-round to eliminating it all together. All bills are still pending.
North Carolina
The North Carolina House passed an effort earlier this year to adopt DST year-round if authorized by Congress. The bill is awaiting further approval and is pending.
A sister bill in the North Carolina Senate also seeks to adopt daylight saving time year-round and is pending.
North Dakota
The most recent attempt to pass a permanent DST bill in North Dakota was killed in 2021, when the legislature voted it down.
The bill would have taken effect if Minnesota, Montana and South Dakota adopted similar measures.
According to Prairie Public Broadcasting, the bill's main sponsor didn't like the amendment requiring those other three states to be on board first, although Montana and Minnesota have passed bills to make the change.
Ohio
Ohio State Rep. Rodney Creech introduced a bill urging Congress to make that would make DST permanent. The bill is still pending.
Creech filed a similar bill in 2021, where it passed the House but died in the Senate.
Oklahoma
An Oklahoma bill to "lock the clock" and permanently establish DST in the state was passed in March 2023 by the state senate. If approved by the House, the bill would still require congressional action to take effect.
In May, another bill declaring support for the Sunshine Protection Act of 2023 was adopted.
Oregon
In 2023, two efforts failed in the Oregon House and Senate aimed at changing the daylight saving time. HB 3102 sought to eliminate daylight saving time and require the state to rely on standard time for the entire year.
SB 1090 sought to abolish one-hour change in time from standard time to daylight saving time and keep the state in standard time for all 12 months of the year, except in a portion of Oregon that adheres to Mountain Time Zone.
Oregon legislators passed a bill in 2019 that would keep Oregon on daylight saving time year-round. But there is one caveat: Because it is in the Mountain Time Zone, Malheur County in Eastern Oregon would be the only place in the state that would not follow this plan.
Of course, that's only if Congress repeals the Uniform Time Act of 1966.
Pennsylvania
The Pennsylvania House narrowly passed a measure in April 2021 to make daylight saving time permanent, pending congressional approval. But the bill failed to gain traction in the senate and died there.
For the 2023 session, State Sen. Scott Martin re-introduced a resolution urging the federal government to repeal the Uniform Time Act of 1966, allowing states to choose for themselves which time procedure to follow. The motion is still pending.
Other bills filed in 2023 looking to abolish daylight saving time, change the state to Atlantic Standard Time and to observe daylight saving time year-round are also pending.
Rhode Island
Rhode Island's state legislature does not appear to have any current bills related to daylight saving time.
In previous years, the state has floated the idea of joining the Atlantic Standard Time zone similar to proposals in Connecticut and New Hampshire. But those proposals have not made much headway.
South Carolina
South Carolina passed a bill in 2020 to make daylight saving time permanent, but it won't take effect unless there is approval by Congress.
South Dakota
A 2022 House bill that would have established permanent daylight saving time for South Dakota was introduced, but died in committee shortly after.
Tennessee
In 2019, Tennessee implemented a law mandating statewide observance of daylight saving time year-round. Although without Congress changing the law, the state law has no effect.
In 2023, there were measures filed to exempt the state from observing daylight saving time if surrounding states exempt themselves. These bills are in "pending-carryover" status, according to NCSL.
Texas
Texas lawmakers have repeatedly attempted to get rid of daylight saving time, but the efforts haven't taken hold. In April 2023, the Texas House approved a bill to permanently stay on daylight saving time but the Senate never voted on it.
Other lawmakers proposed having voters decide if the state should follow daylight saving time in November. However, that plan has yet to receive a vote in either legislative chamber.
Editor's note: A previous version of this story incorrectly stated Texas voters may get to decide in the November election about the time change. While state lawmakers proposed that idea, it has not been approved by the legislature.
Utah
Signed into law in 2020, Utah's move to permanent daylight saving time is contingent on Congressional approval and at least four other western states also making the move. These can include Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Washington or Wyoming.
Vermont
Vermont lawmakers are once again attempting to make daylight saving time permanent in the state with House Bill 329. If the bill makes it out of committee, it will face a vote by the state house before repeating the process in the senate.
The last attempt to change how the state observes daylight saving time was in 2021, when a bill that would have exempted the state from DST failed to make it out of a house committee.
Virginia
The most recent attempt to move Virginia to year-round daylight saving time failed in January 2023 failed in the state senate after a divided vote on the bill.
Washington
Washington state would be on the list of places that don't observe the time change after lawmakers approved permanent daylight saving time in the spring of 2019. It is waiting on Congress.
West Virginia
A bill that would have eliminated daylight saving time in West Virginia — which would have put the state on Eastern time — failed in the house when the 2022 legislative session ended.
Wisconsin
The last notable effort in Wisconsin to eliminate daylight saving time was scrapped in 2017 after social media backlash forced the two legislators who authored the bill to walk it back. The Associated Press reported that the pair faced backlash from constituents and even calls from upset relatives.
One of the sponsors, Rep. Michael Schraa, conceded, “This would be a lot better if we just stayed on daylight saving time.”
Wyoming
Wyoming's legislature passed a measure in March 2020 to allow the state to observe year-round daylight saving time if approved by Congress and if three nearby states adopted the same plan. Those states would need to be from: Colorado, Idaho, Montana, Nebraska, North Dakota, South Dakota or Utah.
The legislature introduced another bill in 2023 to establish Mountain Standard Time year-round but the effort failed.
