Most of Mexico will remain on standard time this spring and fall, but residents of several northern border municipalities, as well as all of Baja California, will adjust their clocks on , as part of a continuing effort to synchronize time with the United States.
The change, mandated by Mexico’s Law of Time Zones, will see clocks moved forward one hour at local time. The seasonal time adjustment will end on , when clocks will be turned back to standard time.
The decision to maintain daylight saving time in these specific areas stems from a 2022 law that largely abolished the practice across most of Mexico, but allowed for exceptions along the U.S. Border. The aim is to facilitate economic activity, cross-border travel, and maintain consistent schedules with neighboring American cities.
The continued observance of daylight saving time in these regions is intended to streamline a range of activities, including border crossings, flight schedules, industrial operations, and school and work hours. Without synchronization, potential disruptions and confusion could arise, particularly for those engaged in cross-border commerce or travel.
The municipalities affected are located in the states of Baja California, Chihuahua, Coahuila, Nuevo León, and Tamaulipas. Specific cities and towns include:
- Coahuila: Acuña, Allende, Guerrero, Hidalgo, Jiménez, Morelos, Nava, Ocampo, Piedras Negras, Villa Unión, and Zaragoza.
- Nuevo León: (List not provided in source material)
- Tamaulipas: Nuevo Laredo, Guerrero, Mier, Miguel Alemán, Camargo, Gustavo Díaz Ordaz, Reynosa, Río Bravo, Valle Hermoso, and Matamoros.
- Chihuahua: Coyame del Sotol, Ojinaga, Manuel Benavides, Janos, Ascensión, Juárez, Praxedis G. Guerrero, and Guadalupe.
- Baja California: (Entire state)
The 2022 legislation, published in the Diario Oficial de la Federación, ended daylight saving time for the majority of the country, but specifically preserved it for the border regions. This decision acknowledged the significant economic and logistical ties between these Mexican communities and their U.S. Counterparts.
The United States will also move its clocks forward on , further reinforcing the rationale for maintaining synchronization. As a result of the U.S. Change, US Pacific Time will be one hour behind Mexico City, US Mountain Time will be aligned with Mexico City, US Central Time will be one hour ahead, and US Eastern Time will be two hours ahead. The UK and Ireland will be seven hours ahead of Mexico, and Central Europe will be eight hours ahead.
Experts at the University of Guadalajara recommend preparing the body for the time change one or two days in advance to minimize fatigue. Suggestions include going to bed earlier, eating a light dinner, avoiding stimulants in the evening, exercising in the morning, reducing screen time before bed, and staying hydrated.
The change in schedule can directly impact work schedules, school start and end times, international crossings, flights, and medical appointments. Failure to account for the adjustment could lead to delays or confusion, particularly for those traveling between Mexico and the United States.
The decision to maintain daylight saving time in these border regions reflects a pragmatic approach to managing cross-border interactions and minimizing disruptions to economic activity. While the majority of Mexico has opted to remain on standard time year-round, these specific areas continue to prioritize alignment with the schedules of their U.S. Neighbors.
