Let me be honest with you—every single year when daylight saving time rolls around, I find myself Googling the same questions: “Do we spring forward or fall back?” “Wait, do I lose an hour of sleep or gain one?” And my personal favorite: “Why are we still doing this?”

Well, 2025 is no different. So I decided to dive deep into everything about daylight saving time 2025, not just for myself, but for all of us who perpetually forget which way the clocks go. Let’s figure this out together.

When Does Daylight Saving Time 2025 Begin?

Mark your calendars (and set about five alarms): Daylight saving time 2025 begins on Sunday, March 9, 2025, at 2:00 AM local time.

This is when we “spring forward”—meaning we lose an hour of sleep. I know, I’m not thrilled about it either. At 2:00 AM, clocks will jump to 3:00 AM. If you’re like me and forget to adjust your clocks before bed, you’ll wake up Monday morning in a panic, convinced you’ve overslept.

Pro tip: Change your clocks before you go to bed on Saturday night (March 8). Your Monday morning self will thank you.

When Does Daylight Saving Time 2025 End?

The good news? We get that hour back! Daylight saving time 2025 ends on Sunday, November 2, 2025, at 2:00 AM local time.

This is when we “fall back.” At 2:00 AM, clocks will return to 1:00 AM, giving us an extra hour of sleep. This is the one day of the year when sleeping in actually feels justified. I usually celebrate by hitting the snooze button guilt-free at least three times.

The Simple Way to Remember: Spring Forward, Fall Back

I’ve used this mnemonic device for years, and it’s never failed me:

Spring forward = Spring (March) → Move clocks forward (lose an hour)
Fall back = Fall (November) → Move clocks back (gain an hour)

It’s so simple, yet every March and November, I still have to repeat it to myself multiple times.

Why Do We Even Have Daylight Saving Time?

This is where things get interesting—and a bit controversial. The whole concept of daylight saving time was originally proposed to make better use of daylight during the longer days of summer. The idea was to shift an hour of daylight from the morning (when many people are sleeping) to the evening (when more people are awake and active).

The practice gained traction during World War I as an energy-saving measure. Germany was the first to implement it in 1916, and other countries, including the United States, followed suit. The logic was straightforward: if people are awake during daylight hours, they’ll use less artificial lighting and conserve energy.

Fast forward to 2025, and we’re still doing it—though the reasoning has become increasingly debated. With modern technology and lifestyle changes, many experts question whether daylight saving time actually saves energy anymore. Some studies suggest the savings are minimal at best.

Which States Don’t Observe Daylight Saving Time 2025?

Here’s something that surprised me when I first learned it: not all U.S. states participate in daylight saving time!

States that DON’T observe daylight saving time:

Hawaii – They’re close to the equator, so daylight hours don’t vary much throughout the year
Arizona (except the Navajo Nation) – The extra evening daylight would mean more air conditioning use, which isn’t ideal in the desert heat

U.S. territories that don’t observe it:

Puerto Rico
U.S. Virgin Islands
American Samoa
Guam
Northern Mariana Islands

I have to admit, I’m a little jealous of these places. They never have to deal with the twice-yearly clock confusion or the disrupted sleep schedules.

The Health Impact: Why That One Hour Matters More Than You Think

I used to think the whole “losing an hour of sleep” thing was overblown. I mean, it’s just one hour, right? Wrong. So very wrong.

Research has shown that the Monday after we spring forward in March sees:

An increase in heart attacks (about 24% higher risk)
More car accidents due to drowsiness
Decreased productivity at work
More workplace injuries
Increased mood disturbances

Our bodies operate on circadian rhythms—internal clocks that regulate sleep-wake cycles. Even a one-hour shift can throw these rhythms off balance, and it can take several days (or even weeks) for some people to fully adjust.

I personally feel like a zombie for at least three days after the March time change. Coffee consumption doubles, patience runs thin, and I find myself irrationally angry at Benjamin Franklin (who’s often credited with the idea, though it’s more complicated than that).

The Fall Time Change: Not All Sunshine and Rainbows

While gaining an hour in November sounds great, it comes with its own challenges. The earlier sunset means:

Driving home from work in the dark
Less time for outdoor activities after work
Increased seasonal affective disorder (SAD) symptoms
Higher rates of depression during the darker months

I notice the shift in my mood every November. By 5:30 PM, it’s pitch black outside, and my brain starts thinking it’s bedtime. I’ve learned to combat this with bright indoor lighting, regular exercise, and the occasional vitamin D supplement (after checking with my doctor, of course).

Countries Around the World: Who Else Does This?

The United States isn’t alone in this practice, though the list of participating countries has been shrinking.

Countries that observe daylight saving time in 2025:

Most of Europe (though they’ve been discussing abolishing it)
Parts of Canada
Parts of Australia
New Zealand
Some Middle Eastern countries

Countries that have abolished it:

Russia (stopped in 2014)
Turkey (stopped in 2016)
Most of Asia (never adopted it)
Most of Africa (never adopted it)
Brazil (stopped in 2019)

There’s a global trend toward abandoning the practice, which brings me to…

Will the U.S. Ever Stop Changing Clocks?

This is the million-dollar question, and honestly, I’m hopeful we’re moving toward a permanent solution.

Several states have passed legislation to observe daylight saving time year-round, but there’s a catch: they need federal approval to do so. The Uniform Time Act of 1966 allows states to opt out of daylight saving time (like Hawaii and Arizona), but it doesn’t currently allow them to stay on daylight saving time permanently.

In 2022, the U.S. Senate unanimously passed the Sunshine Protection Act, which would make daylight saving time permanent nationwide. I remember feeling excited when I heard the news, thinking, “Finally! No more clock changes!”

But here’s where it gets frustrating: the bill stalled in the House of Representatives and hasn’t become law. As of 2025, we’re still switching our clocks twice a year.

The debate continues: Should we stick with standard time year-round, daylight saving time year-round, or keep the current system? Everyone has opinions, and they’re surprisingly passionate.

My Personal Survival Guide for Daylight Saving Time 2025

After years of struggling with the time changes, I’ve developed some strategies that actually help:

For the March “Spring Forward” Change:

Adjust gradually: Start going to bed 15 minutes earlier a few days before the change
Get morning sunlight: This helps reset your circadian rhythm
Avoid caffeine after 2 PM: On the days leading up to and following the change
Stay hydrated: Dehydration makes fatigue worse
Be patient with yourself: Accept that you might feel off for a few days

For the November “Fall Back” Change:

Don’t sleep in too much: Even though you gain an hour, try to wake up at your regular time
Get outside during daylight: Combat the earlier darkness with outdoor time when you can
Adjust your evening routine: The earlier darkness might make you feel tired sooner
Consider a light therapy lamp: This can help with seasonal mood changes
Maintain your exercise routine: Physical activity helps regulate sleep patterns

Technology to the Rescue (Mostly)

One silver lining of living in 2025: most of our devices automatically adjust for daylight saving time. Smartphones, computers, smart home devices—they all update on their own.

But here’s my annual PSA: Don’t forget about your analog clocks!

Every year, I’ve forgotten at least one clock in my house. Last year, it was the microwave. I spent two weeks wondering why dinner always seemed to take longer to cook than expected before I realized the clock was an hour off.

Items to manually check:

Car clocks (unless you have a newer model)
Wall clocks
Microwave and oven clocks
Coffee makers
Alarm clocks (if you still use one)
Watches (if you wear one)

The Debate: What Should We Do Long-Term?

I’ve thought a lot about this, and I’m genuinely torn. Here are the main options:

Option 1: Permanent Standard Time

Pros: Better alignment with natural circadian rhythms, healthier sleep patterns
Cons: Earlier sunsets in summer, less evening daylight for activities

Option 2: Permanent Daylight Saving Time

Pros: More evening daylight year-round, potentially better for retail and recreation
Cons: Very dark mornings in winter, especially problematic for children going to school

Option 3: Keep the Current System

Pros: We’re used to it, provides seasonal variation
Cons: Health impacts, inconvenience, questionable energy savings

Personally? I’m leaning toward permanent standard time. The research on health and natural circadian rhythms is compelling. But I also understand why people love those long summer evenings. It’s not a simple decision.

How Other Countries Are Handling It

The European Union voted in 2019 to end the practice of changing clocks twice a year, with member states choosing whether to stay on permanent standard or daylight saving time. However, implementation has been delayed due to coordination challenges and, well, other global events that took priority.

Mexico stopped observing daylight saving time in most of the country in 2022, keeping only border cities on the practice to stay synchronized with the United States.

It’s interesting to watch this global experiment unfold. Maybe their experiences will inform what we eventually decide to do in the U.S.

Real Talk: The Productivity Impact

As someone who works from home, I’ve noticed the March time change absolutely destroys my productivity for about a week. That lost hour of sleep compounds over several days because I struggle to adjust my schedule.

Studies back this up: Workplace accidents increase by 5-7% on the Monday after springing forward. Lost productivity costs businesses billions of dollars annually. Even school performance drops in the days following the time change.

The November change is slightly better, but the early darkness affects motivation and energy levels. I find myself wanting to wrap up work earlier because it “feels” later than it actually is.

Tips for Parents: Helping Kids Adjust

I’ve talked to parent friends about this, and the time change can be brutal with children, especially young ones who thrive on routine.

Strategies that work:

Gradually shift bedtime by 10-15 minutes in the days before
Maintain consistent meal times
Use blackout curtains to control light exposure
Stick to regular nap schedules
Be patient with crankiness (for kids AND adults!)
Adjust the whole family’s schedule together

One friend told me she marks both time changes on her calendar six months in advance and starts preparing her kids’ schedules a week early. That level of organization impresses me.

Looking Ahead: What to Expect in 2025

As we navigate daylight saving time 2025, I’m hopeful that this might be one of the last years we have to do this dance. The conversation about ending the practice is gaining momentum, and more people are recognizing the downsides.

Whether we end up with permanent standard time, permanent daylight saving time, or (heaven forbid) we keep switching indefinitely, at least we’re having the conversation.

My Final Thoughts

Daylight saving time has been part of American life for over a century, but that doesn’t mean it has to continue. As someone who values both sleep and evidence-based policy, I’m ready for a change—whatever that change might be.

In the meantime, I’ll keep setting my alarms, adjusting my clocks, and drinking extra coffee that Monday after we spring forward. And I’ll be counting down the days until November when I get that glorious extra hour of sleep.

So, mark those calendars:

March 9, 2025: Spring forward (lose an hour)
November 2, 2025: Fall back (gain an hour)

And if you’re reading this in February, start preparing your sleep schedule now. Your body will thank you.
