Is Daylight Saving Time Observed in Mexico?

In Mexico, Daylight Saving Time is known as the horario de verano (summer schedule). It has been observed since 1996 throughout most of the country. Take note that the state of Sonora, as well as some remote villages do not change their clocks.

When is Daylight Saving Time in Mexico?

Throughout most of the country, the dates of Daylight Saving Time in Mexico are different from the United States, which can cause some confusion. In Mexico, Daylight Saving Time begins the first Sunday in April and ends the last Sunday in October. So, on the first Sunday in April Mexicans change their clock forward one hour at 2 a.m. and on the last Sunday in October, they change their clocks back one hour at 2 a.m.

Exceptions
As of 2010, Daylight Saving Time has been extended in some municipalities along the border in order to coincide with the observation of Daylight Saving Time in the United States. The following locations are included in this provision: Tijuana and Mexicali in the state of Baja California, Ciudad Juarez and Ojinaga in Chihuahua state, Acuña and Piedras Negras in Coahuila, Anahuac in Nuevo Leon, and Nuevo Laredo, Reynosa and Matamoros in Tamaulipas. In these locations Daylight Saving Time begins on the second Sunday in March and ends on the first Sunday in November.
