The time change continues to cause some confusion in a large part of the population. There were 26 years during which turning the clock forward for daylight saving time and back for standard time was a norm. In addition, the law that eliminated this practice, issued in 2022, established the Seasonal Time Schedule (DST) for the border strip, which continues to apply the changes to the clock in March and November.
This Sunday, November 2, the time will go back one hour on:
Baja California: the entire state.
Chihuahua: Janons, shields, Juárez, Praxedis G. Guerrero, Guadalupe, Coyame of the sound, onaga and Manuel Benavides.
Coahuila: Ocampo, Acuña, Jiménez, Zaragoza, Piedras Negras, Nava, Guerrero, Hidalgo, Allende, San Juan de Sabinas, Morelos and Villa Unión.
New Leon: Anahuac.
Tamaulipas: Nuevo Laredo, Guerrero, Mier, Miguel Alemán, Camargo, Gustavo Díaz Ordaz, Reynosa, Río Bravo, Valle Hermoso and Matamoros.
The reason that these territories maintain the distinction between summer and winter time is due to the advantage of having the same time on both sides of the border with the United States, since economic and social activity makes the mismatch impractical.
This situation also makes Sonora the only border state where no municipality changes its time, since Arizona does not apply the time change either.
Summer time is a measure to save electrical energy in the summer period; However, the geographical location of Mexico makes this savings minimal compared to what is achieved in countries closer to the poles of the earth. Furthermore, the time change was never well received among the population, who often cited health problems such as sleep disorders and cardiovascular problems.
