Mexico uses four time zones. Most of the country uses Central Standard Time. The Mexico state of Quintana Roo uses Eastern Standard Time, the states of Chihuahua, Nayarit, Sonora, Sinaloa and Baja California Sur use Mountain Standard Time and Baja California Norte uses Pacific Standard Time.

Daylight Saving Time begins at 2:00 a.m. local time on the first Sunday in April. On the last Sunday in October areas on Daylight Saving Time fall back to Standard Time at 2:00 a.m. The names in each time zone change along with Daylight Saving Time. Central Standard Time (CST) becomes Central Daylight Time (CDT), and so forth. The states of Sonora and Quintana Roo do not observe Daylight Saving Time.

In 2010 ten Mexico municipalities which share a border with the United States will begin daylight saving time three weeks earlier on the second Sunday in March and end 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. Read more.

NEW! Authorities in the state of Quintana Roo announced that effective February 1, 2015 at 2:00 am local time the state will advance clocks forward by one hour and observe the Eastern Time Zone.
