If you’re landing at Guadalajara International Airport (GDL) or heading to the beach in Puerto Vallarta, you’re probably thinking about tequila, mariachi, or finding the best torta ahogada. But honestly? You should be thinking about your watch. The Jalisco Mexico time zone isn’t quite as straightforward as it used to be. For decades, Mexico played the same daylight saving time game as the United States and Canada. Then, everything changed.
In late 2022, the Mexican government decided they’d had enough of the "spring forward, fall back" routine. They essentially scrapped Daylight Saving Time (DST) for most of the country.
Now, Jalisco sits comfortably in one time zone all year long. It’s consistent. It’s predictable. Except, of course, when you’re trying to coordinate a Zoom call with someone in New York or London who still changes their clocks twice a year. Suddenly, that one-hour difference becomes two, or zero. It’s a mess if you aren't paying attention.
The Current State of Time in Jalisco
Right now, the state of Jalisco—from the bustling streets of Guadalajara to the blue agave fields of Tequila—operates on Central Standard Time (CST).
In technical terms, that is UTC-6.
Since the 2022 Decree to abolish DST, Jalisco does not move its clocks in April or October. While the U.S. and parts of Canada jump ahead to Daylight Time, Jalisco stays put. This means for half the year, Jalisco is on the same time as Chicago (CST). For the other half, when Chicago moves to CDT, Jalisco is technically "behind" them, even though they share the same longitudinal slice of the map.
It’s a bit weird, right? You’d think being directly south of the Midwest would keep things synced up.
But Mexico’s Congress, led by the push from President Andrés Manuel López Obrador, argued that the constant shifting was bad for health and didn't actually save much energy. The Senate approved the move with 59 votes in favor, and just like that, the "Horario de Verano" was history for the vast majority of the Republic.
Why Border States Are Different
You might hear stories about people crossing into Mexico and the time still changing. That’s because the law wasn't a blanket ban for every single inch of the country. The northern border states, like Baja California, still sync with the U.S. to keep trade moving smoothly. If you're in Tijuana, you're still doing the clock-dance.
But Jalisco isn't a border state.
It’s deep in the heart of the country. Whether you are visiting the spiritual center of Zapopan or the coastal retreat of Careyes, you are firmly in the zone that ignores the spring-forward madness.
Traveling to Puerto Vallarta: The Confusion Point
Here is where it gets genuinely tricky for travelers. Puerto Vallarta is in Jalisco. However, just across the Ameca River lies the state of Nayarit.
For a long time, Nayarit was in a different time zone (Mountain Time). This created a logistical nightmare for tourists. You’d take a taxi for fifteen minutes from your hotel in Nuevo Vallarta (Nayarit) to a dinner reservation in Puerto Vallarta (Jalisco) and suddenly you were an hour late. Or an hour early. Nobody ever knew which.
Thankfully, the Nayarit government eventually shifted the municipality of Bahía de Banderas to match Jalisco. So, for the most part, the "Bay of Banderas" area operates as one cohesive unit. But don't get overconfident. If you venture further north into Nayarit, past the tourist zones, you might still find yourself crossing a time boundary.

Always check your phone's GPS. Usually, the towers update your local time automatically, but if you’re on roaming or a weak signal, your phone might get "sticky" and hold onto the time from the last tower it pinged.
The Economic Impact of a Fixed Clock
Business owners in Guadalajara—Mexico's "Silicon Valley"—have had to adapt. The city is a massive hub for tech, manufacturing, and international trade. Companies like Intel, Oracle, and HP have huge footprints here.
When your headquarters is in California (Pacific Time) and your team is in Jalisco, the gap changes throughout the year.
- During the U.S. Winter: Jalisco is 2 hours ahead of PST.
- During the U.S. Summer: Jalisco is 1 hour ahead of PDT.
It’s a subtle shift, but in the world of global logistics and "just-in-time" manufacturing, that sixty-minute swing matters. Most local managers have just gotten used to it. They keep a dual-clock widget on their desktops.
Real-World Timing: The "Mexican Minute"
We can’t talk about the Jalisco Mexico time zone without talking about the cultural perception of time. If a friend in Guadalajara tells you they’ll meet you at 7:00 PM for cenaduría (dinner), they probably mean 7:30 PM.
This isn't a lack of respect. It’s just the "ritmo" of the city.
The fixed time zone actually fits the lifestyle better. There’s no more week-long "jet lag" every April where everyone is grumpy because they lost an hour of sleep. The sun rises and sets at a relatively consistent time, which is exactly what the proponents of the law intended. They wanted people to follow the biological clock, not a bureaucratic one.
What This Means for Your Flight
Guadalajara’s airport is one of the busiest in Latin America. It serves as a major connection point for Volaris and Aeromexico.
If you are booking a flight with a connection in GDL, pay very close attention to your arrival and departure times. Airlines always list times in the local time of the airport. If you’re flying from Denver to Guadalajara, your departure is Mountain Time, and your arrival is Central Standard Time.
Because Jalisco doesn't change clocks, your "time difference" will depend entirely on what month you are flying.
- From March to November: Most of the U.S. is on Daylight Time.
- From November to March: Most of the U.S. is on Standard Time.
Check your itinerary twice. I've seen plenty of people miss their transport because they assumed the "usual" two-hour gap was still in place.
Why Jalisco Won't Go Back
There is very little political appetite in Mexico to bring back Daylight Saving Time. The Federal Ministry of Health presented data suggesting that the time changes were linked to increased heart attack rates and sleep disorders. While some business sectors grumbled about the lack of alignment with New York markets, the general population seems to prefer the stability.
In Jalisco specifically, the agricultural sector—which is massive—prefers the natural light cycle. Agave farmers don't care what the clock says; they care when the sun hits the fields.
Practical Steps for Travelers and Expats
If you’re planning to live or travel in Jalisco, don't rely on your memory of how things "used to be." The 2022 law was a permanent shift, not a temporary experiment.
Disable manual time settings. Go into your smartphone settings and ensure "Set Automatically" is toggled on. This allows the network to dictate the time based on your current location.
Confirm with your hotel. If you have a tour departing early in the morning, ask the front desk: "What is the local time right now?" It sounds silly, but it’s the safest way to ensure you aren't operating on an old setting.
Coordinate meetings carefully. Use tools like WorldTimeBuddy or TimeAndDate. These sites have updated their databases to reflect Mexico’s new laws. If you manually calculate the time difference based on old info, you will be wrong.
Check your smart home devices. Sometimes, older smart plugs or IoT devices have "hard-coded" DST rules based on their original firmware. If your outdoor lights in Ajijic are turning on an hour late, you might need to manually update the device's location or timezone settings in the app.

The Jalisco Mexico time zone is now a year-round fixture of Central Standard Time. It represents a broader move toward prioritizing health and local rhythm over international synchronization. It’s one less thing to worry about twice a year, as long as you know the rules of the game before you land.
Make sure your flight alerts are active on your phone. If you're driving in from a neighboring state like Michoacán or Colima, they follow the same rules, so you won't have any issues there. The only "danger zones" for time confusion remain the border states and the deep mountains of the North. In the land of tequila and sunshine, the clock stays steady.
