You’re standing at the Cancun airport, staring at your phone. It says 3:00 PM. The giant analog clock on the wall says 3:00 PM. But your flight confirmation email—the one you’ve checked six times—insists your boarding starts in ten minutes. You panic. Did you lose an hour? Did the "spring forward" thing happen overnight while you were sleeping off a margarita?
Honestly, if you're confused, you aren't alone.
The short answer is that for most of the country, the answer to does mexico have time change is now a resounding "no." But because nothing is ever truly simple when it comes to international borders and local politics, there are some pretty massive exceptions that could leave you stranded at a bus station or missing a dinner reservation if you aren't careful.
Mexico basically broke up with Daylight Saving Time (DST) recently. It was a messy divorce. For decades, the country followed the same rhythmic shifting of clocks as the United States and Canada. Then, in late 2022, the Mexican Senate decided they’d had enough of the "horario de verano." They passed a law that effectively ended the practice across the vast majority of the republic.
Why? The government argued that the energy savings were negligible—less than 1% of total national consumption—while the negative impacts on health, like sleep disruption and heart health, were backed by enough evidence to make the change.
The Big Shift: Why Most of Mexico Stopped Changing Clocks
On October 30, 2022, most Mexicans moved their clocks back one last time. They haven't touched them since.
This was a huge deal.
For a country that relies heavily on tourism and trade with its northern neighbor, opting out of the global clock-shifting game was a bold move. It means that for half the year, Mexico City is on the same time as Chicago. For the other half? It’s an hour behind. It’s a logistical headache for business calls, but a godsend for locals who were tired of feeling like zombies every April.

Most of the country now stays on Standard Time year-round. This includes heavy hitters like Mexico City, Guadalajara, Monterrey, and the popular Pacific Coast spots like Puerto Vallarta and Mazatlán. If you are heading to the heart of the country, you can basically forget that the concept of "springing forward" ever existed.
But wait.
The exceptions are where things get hairy. You can't just set your watch and assume you're good.
The "Border Strip" Exception: Where the Clocks Still Tick
If you’re visiting the border, the rules change completely.
The Mexican government isn't totally oblivious to reality. They realized that cities like Tijuana, Mexicali, and Ciudad Juárez are deeply intertwined with their U.S. counterparts. If San Diego changes its time and Tijuana doesn't, the border crossing—which is already a chaotic dance of thousands of people every morning—becomes a nightmare.
So, the Border Strip (Franja Fronteriza) still observes Daylight Saving Time.
This applies to a 20-kilometer (about 12 miles) zone along the U.S. border. These towns synchronize their clocks perfectly with the United States. When California, Arizona (mostly), New Mexico, and Texas shift their clocks, these specific Mexican municipalities shift right along with them.
The specific spots that still change time:
- Baja California: This whole state stays in sync with the U.S. Pacific Time Zone. Tijuana, Ensenada, and Mexicali will still "spring forward" and "fall back."
- Chihuahua: Key cities like Ciudad Juárez and Ojinaga.
- Coahuila: Including Acuña and Piedras Negras.
- Nuevo León: Only the tiny stretch of Anáhuac.
- Tamaulipas: Cities like Nuevo Laredo, Reynosa, and Matamoros.
If you are crossing the bridge from El Paso to Juárez, your phone will likely handle it fine. But if you start driving south toward Chihuahua City, you might suddenly find yourself in a different time zone within two hours. It's weird. It's confusing. But it's the law.

The Quintana Roo Outlier: Why Cancun is Always Different
Then there's Quintana Roo.
This state is the home of Cancun, Playa del Carmen, Tulum, and Cozumel. They are the rebels of the Mexican time system. Years ago, even before the national ban on DST, Quintana Roo decided they wanted more "sunlight" for tourists. They created their own time zone called Zona Sureste (Southeastern Zone).
Quintana Roo never changes its clocks. Not for the U.S., not for Mexico City, not for anyone.
They stay on what is essentially Eastern Standard Time (EST) all year. This was a strategic move to give tourists an extra hour of daylight on the beach before the sun sets. Because they don't shift, their relationship with other cities changes throughout the year.
- In the Winter: Cancun is the same time as New York and one hour ahead of Mexico City.
- In the Summer: When the U.S. moves to Daylight Saving Time, Cancun is suddenly one hour behind New York but stays one hour ahead of Mexico City.
Basically, if you’re heading to the Riviera Maya, your phone might get confused if it pings a tower that hasn't updated its location data correctly. Always trust the hotel's lobby clock over a wandering GPS signal in remote parts of Tulum.
What This Means for Your Travel Logistics
You've got to be proactive.
Most people assume their smartphones are infallible. In 2026, they usually are, but the transition zones are where the glitches happen. If you’re traveling near the "border" of a time-changing state and a non-changing state (like moving from Quintana Roo into neighboring Yucatán to see Chichén Itzá), you could easily gain or lose an hour without realizing it.
Business and Meetings
If you are working remotely from a beach in Oaxaca, remember that your 9:00 AM meeting with a New York client is at 8:00 AM for part of the year and 9:00 AM for the rest. Mexico City no longer follows the U.S. schedule. This has caused a lot of "you're late" or "I'm early" emails since the 2022 law took effect.
Flights and Buses
Airlines are generally good about this, but local bus lines (like ADO) operate on the local time of the station you are departing from. If you're taking a bus from Mérida (Yucatán) to Cancun (Quintana Roo), you are crossing a time zone boundary.
Sonora: The Arizona Twin
Just a quick note on Sonora. Like Arizona in the U.S., the Mexican state of Sonora does not observe Daylight Saving Time. They’ve had this agreement for years to keep the Arizona-Sonora "megaregion" economically synced. So, if you're in Puerto Peñasco (Rocky Point), the clocks stay put, just like they do in Phoenix.
Why the Change Actually Happened: The Real Story
It wasn't just about sleep.
The Mexican President at the time, Andrés Manuel López Obrador, was a vocal critic of DST for years. He often called it "the clock of the rich" or a "foreign imposition." While that sounds like political theater, there was a genuine sentiment among the rural population that shifting clocks was an urban annoyance that didn't help farmers or people living in high-heat areas.
Health experts in Mexico, including those from the Ministry of Health, presented data suggesting that the sudden shift in time led to an increase in nervous system disorders, depression, and even heart attacks in the days following the change. While the U.S. continues to debate the Sunshine Protection Act, Mexico simply pulled the trigger and ended it.
The result? A country that is largely on "natural time" (Standard Time), based on where the sun is actually at its highest point at noon.
Actionable Steps for Your Next Mexico Trip
Don't let a clock shift ruin your vacation. Since the answer to does mexico have time change depends entirely on your GPS coordinates, here is how you handle it:
- Check the State, Not the Country: Before you land, Google the specific state. Are you in Quintana Roo? No change. Baja California? Changes with San Diego. Mexico City? No change.
- Manual Overrule: If you are traveling between regions (like a road trip from Monterrey to Texas), consider turning off "Set Automatically" on your phone's time settings. This prevents your phone from jumping back and forth if it catches a signal from a tower across a time zone line.
- Confirm with the Locals: If you have a tour booked for 8:00 AM, ask the hotel front desk: "¿Es hora local o hora de la ciudad?" (Is it local time or city time?). This is especially vital in places like the border of Yucatán and Quintana Roo.
- Meeting Planning: Use a tool like WorldTimeBuddy. Don't assume that because it's 2:00 PM in Dallas, it's 2:00 PM in Mexico City. After the 2022 law, that parity only exists for part of the year.
- Watch the Border: If you are driving across the border in 2026, remember the change happens on the second Sunday in March and the first Sunday in November. If you are in that 20km border zone, you are on U.S. time. If you drive 30 minutes south, you are likely an hour off.
Mexico’s decision to ditch the time change was about simplicity and health, but for the unprepared traveler, it adds a layer of complexity. Stay aware of the "Border Strip" and the "Southeastern Zone," and you’ll never miss your flight.
