In 2010 ten Mexico municipalities which share a border with the United States began a pattern of starting daylight saving time three weeks earlier on the second Sunday in March and ending on the first Sunday in November. Previously all of Mexico, with the exception of the state of Sonora which does not observe daylight saving time, began and ended daylight saving time at the same time. The Congress of Mexico passed legislation in December 2009 which allowed these ten border cities to adopt a daylight saving time pattern consistent with the United States. The municipalities which are now permitted by law to observe daylight saving time consistent with the United States are:

City, State
Acuna, Coahuila
Anahuac, Nuevo Leon
Juarez, Chihuahua
Matamoros, Tamaulipas
Mexicali, Baja California
Nuevo Laredo, Tamaulipas
Ojinaga, Chihuahua
Piedras Negras, Coahuila
Reynosa, Tamaulipas
Tijuana, Baja California

This change in daylight saving time observance was requested by local governments and political leaders to help facilitate commerce with the United States. Industries such as transportation and banking were especially affected by the differences in daylight saving time. In some cases businesses had to to open an hour early than usual to conduct business with US companies during the 3 weeks in March when the two countries were on different times.

Since 2010 other smaller municipalities and towns near the border with the United States have begun to unofficially observing daylight saving time consistent with the United States . The chart below indicates municipalities that are officially and unofficially observing daylight saving time consistent with the United States.

The observation of daylight saving time for municipalities observing daylight saving time consistent with the United States begins at 2:00 a.m. local time on the second Sunday in March. On the first Sunday in November these areas will return to Standard Time at 2:00 a.m. local time.
