When Does DST Start and End in Mexico?

In most of Mexico, including its capital Mexico City, Daylight Saving Time (DST) runs from the 1st Sunday of April to the last Sunday of October. However, there are several exceptions:

  • The state of Sonora does not change its clocks. The rationale is to stay in sync with the neighboring US state of Arizona, where Mountain Standard Time (MST) is observed all year. In the map below, Sonora is the yellow area on the left.
  • Quintana Roo has opted out of following the country's DST regime. Following the establishment of its own time zone in 2015, Mexico's easternmost state is observing EST year-round. In the map below, Quintana Roo is the yellow area on the right.
  • The state of Baja California and many other locations close to the country's northern border follow the DST schedule of the United States. This includes cities like Tijuana, Ciudad Juárez, and Ojinaga (please see cities marked “north” in the table below). Here, the DST period starts on the 2nd Sunday in March and ends on the 1st Sunday in November.
