Mexico, a vibrant country rich in culture and diverse landscapes, spans across multiple time zones. Understanding these time zones is crucial for travelers, business professionals, and anyone connecting with Mexico. This guide will clarify the different time zones in Mexico, helping you stay on schedule whether you’re planning a vacation to the beaches of Cancun or coordinating a call with colleagues in Mexico City.
How Many Time Zones Does Mexico Have?
Mexico is divided into four primary standard time zones, mirroring its neighbor to the north, the United States. These zones ensure that different regions of this large country experience sunrise and sunset at roughly similar times, optimizing daily life and activities. Knowing which time zone applies to your destination within Mexico is essential for accurate timekeeping.
Mexico’s four time zones are:
- Pacific Standard Time (PST): Also known as Zona Noroeste, this time zone is observed in Baja California. It is UTC-8. Cities like Tijuana operate on PST.
- Mountain Standard Time (MST): Referred to as Zona Pacífico, MST covers a significant portion of western Mexico, including states like Baja California Sur, Nayarit, Sinaloa, and Sonora. This zone is UTC-7. Hermosillo is a key city in the MST zone.

- Central Standard Time (CST): Known as Zona Centro, CST is the most widely observed time zone in Mexico. It includes major cities like Mexico City and Guadalajara and covers a large swathe of the country, including most of Chihuahua. CST is UTC-6.
- Eastern Standard Time (EST): Designated as Zona Sureste, EST is observed in Mexico’s easternmost state, Quintana Roo, home to popular tourist destinations like Cancun and Playa del Carmen. EST is UTC-5.
Daylight Saving Time (DST) in Mexico: What You Need to Know
It’s important to note recent changes regarding Daylight Saving Time in Mexico. As of October 30, 2022, Daylight Saving Time was abolished for most of Mexico. This means that most of the country no longer adjusts clocks forward in the spring or back in the fall.
However, there is an exception. Municipalities along the northern border of Mexico, near the United States, still observe Daylight Saving Time and follow the US DST schedule. This is to maintain synchronization with business and daily life across the border. Therefore, if you are in border cities, be aware of potential DST changes, while most of Mexico operates on standard time year-round.
A Brief History of Time Zones in Mexico
Mexico adopted standard time in 1922, a significant shift from using solar mean time, which varied by location’s longitude. Before 1922, each Mexican city operated on its own local solar time. Mexico City, for instance, was about 6 hours, 36 minutes, and 36 seconds behind GMT (Greenwich Mean Time).
In 1922, Mexico standardized its time, initially setting it to 7 hours behind GMT. Later, in 1928, Mexico City shifted to Central Standard Time (CST), which it continues to observe as its standard time today. Historically, Mexico started with just two time zones, gradually increasing to the current four to better accommodate the geographical spread of the country. Quintana Roo’s adoption of Eastern Standard Time in 2015 was one of the more recent changes, reflecting the region’s growing ties and convenience for eastern travelers.
Understanding Mexico Time Zones is essential for smooth travel and communication. Whether planning a trip or managing international connections, this guide provides a clear overview to help you navigate time across Mexico.
