Knowing the exact hora en CDMX (time in Mexico City) is essential whether you're joining a remote conference call, booking a flight, or timing a phone call to friends and family. Mexico City operates on Central Standard Time, but changes in national legislation regarding daylight saving time mean that keeping track of the local clock requires up-to-date knowledge. Let's look at how Mexico's capital manages time, what offset it currently uses, and how to avoid scheduling mix-ups.
Mexico City operates in the Central Time Zone (Zona Centro). For most of the year, the capital observes Central Standard Time, which corresponds to UTC-6. Unlike many regions in the United States and Canada, mainland Mexico officially eliminated standard daylight saving time nationwide in late 2022 following a decree by the federal government. This means clocks in Mexico City no longer spring forward in March and fall back in October, which has permanently altered how the city aligns with international partners during the spring and summer months.
Current Time Zone and UTC Offset for Mexico City
Mexico City sits firmly in the UTC-6 zone (Tiempo del Centro). Because the federal government abolished seasonal clock changes for most of the country, the capital maintains this UTC-6 offset year-round. Certain northern border municipalities near the U.S. border still observe daylight saving time to maintain commercial alignment with neighboring American states, but Mexico City does not follow this exception.
If you're coordinating schedules across borders, this fixed offset simplifies things for part of the year while introducing differences during others. For example, when New York is on Eastern Standard Time (UTC-5) during the winter, Mexico City is exactly one hour behind. When New York shifts to Eastern Daylight Time (UTC-4) in the spring, the gap widens to two hours because Mexico City stays fixed on UTC-6. Lonely Planet has analyzed this important topic in great detail.
- Standard Time Offset: UTC-6 year-round.
- Daylight Saving Time Status: Abolished for the capital in 2022.

Historical Context: The End of Daylight Saving in Mexico
For over two decades, Mexico utilized Horario de Verano (Daylight Saving Time), moving clocks forward one hour from the first Sunday in April until the last Sunday in October. The stated goal was energy conservation and making better use of natural daylight. However, public dissatisfaction, minimal documented energy savings in modern households, and health concerns associated with circadian rhythm disruption prompted a comprehensive review.
In October 2022, the Mexican Congress passed a new Law of Time Zones (Ley de Husos Horarios en los Estados Unidos Mexicanos). This legislation established a uniform standard across most of the national territory, abolishing the bi-annual clock change for Mexico City and the majority of states. Understanding this shift is critical if you are reading older travel guides or outdated blog posts that still reference spring and autumn adjustments for the capital.
How Mexico City Time Compares to Major Global Hubs
Coordinating international meetings requires careful attention to how other countries handle seasonal shifts. Because Mexico City no longer adjusts its clocks, its time difference relative to regions that do observe daylight saving time changes twice a year.
- New York (EST/EDT): During winter months, New York is one hour ahead of Mexico City. During summer months, when New York shifts forward, it is two hours ahead of Mexico City.
- London (GMT/BST): In the winter, London (UTC+0) is six hours ahead of Mexico City. In the summer, when the UK adopts British Summer Time (UTC+1), London jumps to seven hours ahead.
- Los Angeles (PST/PDT): Los Angeles shares the same seasonal shifts as New York, meaning it sits two hours ahead of Mexico City in the winter and three hours ahead in the summer.
- Bogotá (COT): Bogotá operates on UTC-5 year-round. Because Bogotá does not observe daylight saving time either, it remains consistently one hour ahead of Mexico City every single day of the year.
Practical Tips to Avoid Scheduling Errors
When you're dealing with cross-border schedules, relying on memory is a recipe for missed meetings. Smart execution involves a few straightforward habits:
- Use Explicit Time Zone Identifiers: When scheduling calendar invites with colleagues in Mexico City, use specific timezone codes like America/Mexico_City rather than generic labels like "Central Time," which can easily be confused with Central Time in the U.S. and Canada.
- Double-Check Your Devices: Modern smartphones and computers automatically update based on network time protocols, but ensure your device's automatic time zone feature is turned on so it pulls the correct location data from local cell towers or Wi-Fi routers.
- Verify Flight Schedules Directly: If you're traveling through the AICM (Benito Juárez International Airport), always confirm departure and arrival times directly on the airline's official app or portal, as flight manifests display local time.
Common Mistakes to Avoid
Travelers and remote workers frequently trip over a few persistent assumptions regarding Mexican time zones.
Don't assume Mexico City matches U.S. Central Time year-round. While they share the exact same offset during standard winter months, the moment U.S. jurisdictions spring forward in March, the two regions fall out of sync by an hour.
Another common error is assuming resort destinations like Cancún or tourist hubs like Tijuana follow the exact same rules. Quintana Roo operates on a distinct Eastern zone (UTC-5) with no daylight saving time, and Baja California's northern zone aligns with Pacific Time while observing U.S. border daylight saving rules. Always check the specific municipality if you're traveling outside the capital.
Frequently Asked Questions
Does Mexico City still change its clocks in the spring and fall?
No. Mexico City permanently ended daylight saving time in late 2022. Clocks stay on Central Standard Time (UTC-6) throughout the entire year.
What is the exact time difference between Mexico City and New York City?
It depends on the time of year. From November to March, New York is one hour ahead of Mexico City. From March to November, because New York observes daylight saving time while Mexico City does not, New York is two hours ahead.
How can I verify the exact official time in Mexico City right now?
You can check the official atomic clock time maintained by the Centro Nacional de Metrología (CENAM) or rely on the native clock app on any internet-connected smartphone set to automatic network time.
Why do some parts of Mexico still have different times?
The federal time law allows northern border states and municipalities that share intense economic ties with U.S. cities to maintain matching daylight saving schedules to avoid friction in cross-border commerce and daily transit.
