When Does DST Start and End in Mexico?
Most of Mexico, including its capital Mexico City, doesn't use Daylight Saving Time (DST). However, some exceptions exist for the locations that follow the DST schedule of the United States:
- Baja California observes DST and uses the same time zones as neighboring California in the US. Here, the DST period starts on the second Sunday in March and ends on the first Sunday in November.
- Sonora does not change its clocks to stay in sync with the neighboring US state of Arizona, where Mountain Standard Time (MST) is observed all year.
- Municipalities near the country's northern border with the US keep the DST schedule for practical and socioeconomic reasons. This includes the municipalities Ciudad Juárez and Ojinaga in Chihuahua, Colombia in Nueva Leon, and Reynosa in Tamaulipas.
