It happens twice a year like clockwork. You wake up feeling like a zombie, or you suddenly realize it's pitch black at 4:30 PM. We all go through it, but if you're asking what state does the time change, the answer is basically "almost all of them." Except for two rebels. And a handful of territories that decided long ago they weren't interested in the chaos.
Every spring, we "spring forward." Every fall, we "fall back." It’s a ritual that supposedly saves energy, though modern studies from places like the National Bureau of Economic Research suggest that might be a total myth. In fact, some data shows we actually use more electricity because we're cranking the AC during those extra sunny evening hours.
The Geography of Lost Sleep
So, let's get specific. Forty-eight states participate in this biannual ritual. If you live in California, New York, Florida, or Texas, you're changing your clocks. You're losing an hour of sleep in March and gaining it back in November. It’s the law of the land under the Uniform Time Act of 1966.
But then there's Arizona.
Arizona is the big outlier. Except for the Navajo Nation—which does observe Daylight Saving Time (DST) to stay in sync with its tribal lands in Utah and New Mexico—the rest of the state stays on Standard Time year-round. Why? Because it’s already hot enough. Nobody in Phoenix wants an extra hour of 110-degree sunlight at 8:00 PM. They want the sun to go down so the desert can finally start to cool off. It’s a matter of survival, honestly.
Hawaii is the other one. Being so close to the equator, their day length doesn't actually shift that much throughout the year. If you're in Honolulu, the difference between the longest day of the year and the shortest is only about two hours. In a place like Seattle, that difference is more like eight hours. For Hawaiians, moving the clocks would be a lot of effort for almost zero benefit.
The Territorial Divide
It's not just the 50 states we have to think about. If you're traveling to Puerto Rico, the U.S. Virgin Islands, American Samoa, Guam, or the Northern Mariana Islands, leave your watch alone. These territories stay on Standard Time.
Imagine living in American Samoa. You’re in the Southern Hemisphere. If they followed the U.S. mainland’s schedule, they’d be "springing forward" right as they headed into winter. It would be a geographical disaster. They’ve opted out, and frankly, they seem a lot less stressed about it than the rest of us.
Why Do We Even Do This?
The history is kind of messy. People love to blame farmers. "The farmers wanted more light!" Actually, no. Farmers historically hated Daylight Saving Time. They work by the sun, not the clock. If the sun rises at 5:00 AM but the hired hands don't show up until "6:00 AM" because the clock moved, the farmer loses an hour of morning productivity.
The real push came from retailers and the leisure industry. If it's light out when people get off work, they’re more likely to stop at the store, go to the golf course, or grab dinner out. In the 1980s, the candy industry even lobbied to extend DST into November so kids would have more light for trick-or-treating. It’s always about the money.
The Health Toll Nobody Mentions
We joke about being tired, but the data is actually pretty dark. When we "spring forward" in March, heart attack rates spike. A study published in the Open Heart journal noted a 24% increase in heart attacks on the Monday immediately following the time change.
Our bodies are governed by circadian rhythms. These are ancient biological processes that don't care about federal mandates. When you abruptly shift the social clock, you create "social jetlag." Your internal hormones are yelling that it’s 6:00 AM, but your boss expects you at your desk because the wall clock says 7:00 AM.
It's not just hearts, either. Car accidents increase. Workplace injuries go up. We are a nation of sleep-deprived people, and forcing a collective 60-minute shift overnight is like giving the entire country a mild case of whiplash.
The Sunshine Protection Act: A Ghost in the Senate
You might remember a few years ago when it seemed like this was all going away. The Sunshine Protection Act actually passed the Senate with a unanimous vote in 2022. It felt like a miracle. For a brief moment, Republicans and Democrats agreed on something: stop the switching.
The plan was to make Daylight Saving Time permanent. No more falling back.
But then it hit the House of Representatives and... nothing. It stalled. Why? Because while everyone hates the change, nobody can agree on which time to keep. Doctors and sleep scientists actually argue that we should stay on Standard Time (the winter time). They say morning light is crucial for setting our biological clocks and that permanent DST would lead to kids waiting for school buses in pitch-black darkness until 9:00 AM in some northern states.
How to Handle the Next Shift
Since we're stuck with it for now, you have to be smart. You can't just wing it.

First, stop drinking caffeine by noon on the Saturday before the change. Your nervous system is already going to be on edge; don't add fuel to the fire. Second, try to go to bed 15 minutes earlier each night starting on Thursday. It sounds like a "mom" tip, but it works. It bridges the gap.
If you’re in one of the 48 states where the time change happens, your smartphone will handle the heavy lifting. But don't forget the "dumb" appliances. The microwave, the oven, and that one analog clock in the hallway you always forget about. Those are the ones that will trip you up on Sunday morning when you’re trying to figure out why you’re suddenly late for brunch.
Is Your State Trying to Opt Out?
The map is changing. Well, the legal landscape is, anyway. Over the last few years, dozens of states have passed internal legislation to stop the clock change. States like Maine, Oregon, Tennessee, and Washington have all said, "We're done."
The catch? They can't actually do it without federal approval. Under current law, a state can opt out of DST and stay on Standard Time (like Arizona), but they are not allowed to stay on permanent Daylight Saving Time without an act of Congress. So, these state laws are basically "trigger laws"—they're sitting on the books, waiting for Washington D.C. to give the green light.
What State Does the Time Change? A Summary of the Current Map
If you’re looking for a quick breakdown of where we stand right now:
- The Changers: 48 states, including the big ones like California, Texas, Florida, and the entire East Coast.
- The Keepers (Standard Time): Arizona (mostly) and Hawaii.
- The Territories: Puerto Rico, Guam, American Samoa, and the Virgin Islands.
- The "We Want to Change" Group: At least 19 states have passed legislation to stay on permanent DST, but they are currently blocked by federal law.
It’s a mess. It’s a 100-year-old experiment that we’ve just sort of accepted as reality. But for now, unless you’re moving to Tucson or Honolulu, you’d better keep those "Spring Forward" and "Fall Back" reminders in your calendar.
Actionable Steps for the Next Time Change
Since most of us are stuck in the cycle, here is how you actually survive it without losing your mind.
Shift your light exposure. Light is the primary driver of your internal clock. On the Sunday of the time change, get outside as soon as the sun comes up. Go for a walk. Force those photons into your retinas. It tells your brain, "Hey, this is the new morning," and helps reset your melatonin production.
Audit your bedroom. If you're moving into Daylight Saving Time, the sun will be up later. If your bedroom isn't dark, you won't sleep. Get blackout curtains. Seriously. They cost twenty bucks and can save your sleep quality during the long summer days.
Check the smoke detectors. This is the classic advice for a reason. When you change the clocks, change the batteries. Or at least test them. It’s a simple habit that actually saves lives, unlike the time change itself, which mostly just makes us grumpy and prone to forgetting where we parked our cars.
Understand your local laws. Keep an eye on your local state legislature. The movement to end the time change is gaining steam every year. If your state has a pending bill, calling your representative might actually move the needle. We are closer to ending this practice now than we have been in decades.
Ultimately, the question of what state does the time change is a question of geography and law. But the question of how it affects you is a matter of biology. Take it seriously, prep your body, and maybe keep an extra pot of coffee ready for that first Monday in March.

Next Steps to Take:
- Check your state's current legislative status on the Sunshine Protection Act to see if a "trigger law" is already in place for your area.
- Set a recurring calendar alert for three days before the March time change to begin shifting your sleep schedule by 15-minute increments.
- Invest in a high-quality sleep mask or blackout curtains to mitigate the impact of late-evening sunlight during the summer months.
