You're standing in the middle of the Zócalo, the sun is beating down on the ancient stones of the Templo Mayor, and you realize something feels off. You check your phone. Then you check your watch. If you’re visiting from the United States or Canada, there’s a massive chance your schedule is already a mess. Why? Because the current time in CDMX isn't as predictable as it used to be.
Honestly, the biggest mistake people make is assuming Mexico City still follows the "spring forward, fall back" dance. They don’t. Not anymore. In late 2022, Mexico’s Congress decided they were done with Daylight Saving Time (DST) for good. This has created a permanent, year-round shift that catches even the most seasoned business travelers off guard.

The Reality of Central Standard Time (CST) in Mexico City
Mexico City is strictly on Central Standard Time (CST), which is UTC-6. This is a constant. No shifting, no adjustments, no panic at 2:00 AM on a random Sunday in March. While the rest of the world is frantically trying to remember which way the clock goes, CDMX stays exactly where it is.
The current time in Mexico City is currently 1 hour behind New York (EST) and 2 hours ahead of Los Angeles (PST). But here is the kicker: that gap changes when the U.S. switches to Daylight Saving Time.
Between March and November, when the U.S. moves to Daylight Saving Time (EDT and PDT), the time difference shifts. New York becomes 2 hours ahead of CDMX, and Los Angeles becomes only 1 hour behind. It’s a total headache for scheduling Zoom calls if you aren't paying attention.
Why Mexico Quit Daylight Saving Time
It wasn't just a random whim. President Andrés Manuel López Obrador pushed for this change based on a few key factors. First, the energy savings were basically negligible—around 0.16% of national consumption. Not exactly the revolution people hoped for in 1996 when the policy started.
Second, the health impact was a real concern. Sleep experts in Mexico argued that the constant switching was messing with people's circadian rhythms. If you've ever felt that "time zone hangover" without actually flying anywhere, you know exactly what they mean.
Time in CDMX: A Practical Comparison for Travelers
To keep it simple, here is how the current time in CDMX stacks up against major hubs right now (assuming we are in Northern Hemisphere winter):
- New York / Toronto (EST): You are 1 hour ahead of Mexico City.
- Chicago / Dallas (CST): You are perfectly synced with Mexico City.
- Denver / Phoenix (MST): You are 1 hour behind Mexico City.
- Los Angeles / Vancouver (PST): You are 2 hours behind Mexico City.
- London (GMT): You are 6 hours ahead of Mexico City.
But remember! This only holds true until the second Sunday of March. Once the U.S. and Canada "spring forward," you have to add an extra hour of difference to almost all of those calculations.
The Border Exception: Where it Gets Weird
If you think you've got it figured out, Mexico’s northern border is here to humble you. While Mexico City stopped using DST, several municipalities along the U.S. border kept it. This was a strategic move to keep cross-border trade and commuting from becoming a logistical nightmare.
Cities like Tijuana, Mexicali, Ciudad Juárez, and Nuevo Laredo still change their clocks to match their U.S. neighbors. So, if you are flying from Mexico City to Tijuana, you aren't just crossing a state line; you're entering a different time reality altogether.
What This Means for Your Trip
When you land at AICM (Aeropuerto Internacional Ciudad de México), don't trust your phone immediately if it hasn't updated via the local cell network. I’ve seen people miss dinner reservations at Pujol—which, let's be real, is a tragedy—because their phone was stuck on "Auto-Time Zone" based on a flight plan rather than the local tower.
The city moves at its own pace. "Ahorita" (the famous Mexican expression for "in a little bit") might mean five minutes or five hours, but the actual clock is rock steady.
Common Misconceptions About Mexico's Time Zones
Many people think all of Mexico is on the same time. Nope. There are actually four distinct time zones across the country.
- Zona Centro: This covers Mexico City and the vast majority of the country.
- Zona Pacífico: States like Nayarit and Sinaloa.
- Zona Noroeste: Baja California.
- Zona Sureste: This is Quintana Roo (Cancun, Tulum).
Quintana Roo is the "rebel" state. They don't observe DST either, but they stay on Eastern Standard Time year-round to give tourists more "sunlight hours" on the beach. If you are flying from CDMX to Cancun, you will almost always lose an hour.
Practical Steps to Stay on Schedule
If you are managing a team or planning a trip, do not rely on your memory of how the time "used to be."
- Update your calendar settings: Specifically set your "Primary Time Zone" to Mexico City (CST) rather than just "Central Time," as some apps still default to U.S. Central rules.
- Manual check: Use a site like timeanddate.com to verify the current time in CDMX before any high-stakes meetings.
- The "Border Rule": If your travel involves any city within 20 kilometers of the U.S. border, double-check if they are part of the DST exception group.
The most important thing to remember is that Mexico City is now permanently anchored to the sun's natural cycle. It’s a bit more "old school," and honestly, the city is better for it. Just make sure you aren't the one showing up an hour late to the party.
