On March 8, 2026, clocks in the northern border region of Mexico will be moved forward by one hour.
This change aligns the Mexican border states with the U.S. time zones to streamline commercial activities. Why does this matter? It ensures that businesses and individuals can operate seamlessly across the border.
The states implementing DST include Baja California, Chihuahua, Coahuila, Nuevo León, and Tamaulipas.
Sonora does not observe DST, maintaining a consistent time zone throughout the year.
DST will remain in effect until November 1, 2026.
The decision to maintain DST in the northern border region stems from the necessity to synchronize economic and daily activities with the United States. This synchronization impacts various sectors, including trade, labor, education, and tourism. The elimination of DST in the rest of Mexico in 2022 aimed to establish a permanent standard time; however, the border region continues to adhere to DST for practical reasons.
While DST provides longer daylight hours in the evening, it can disrupt the body's natural biological clock. Studies suggest a potential increase in heart attacks and strokes immediately following the spring time change. Individuals with seasonal affective disorder may also experience adverse effects.
