Set your clock ahead one hour Sunday, March 10, 2013.

Traditionally Daylight Saving Time starts the first Sunday in April and ends the last Sunday in October. Most of Mexico follows these traditional dates.

In 2007 the United States revised the schedule so that Daylight Saving Time begins the second Sunday in March and ends the first Sunday in November. For years the different Daylight Saving Time dates caused confusion for many living in the United States-Mexico border area.

In 2011 Mexican border cities--including Tijuana--started following the current United States Daylight Saving Time schedule in which clocks are set forward one hour the second Sunday in March.

Those with Mexican cell phones should be aware the time displayed on their cell phone between the second Sunday in March and the first Sunday in April may be in error by being one hour behind the time in the California and Baja California. The time displayed on their cell phone may reflect the time in the majority of Mexico based on the traditional dates for Daylight Saving Time.
