Sun Mar 08 09:10:00 UTC 2026: ### Border Cities in Chihuahua to Spring Forward for Daylight Saving Time

Ciudad Juárez, March 7, 2026 – Residents of Ciudad Juárez and other border cities in Chihuahua, Coahuila, Nuevo León, and Tamaulipas are preparing to set their clocks forward by one hour tonight as Daylight Saving Time (DST) comes into effect. The change, mandated to align with the United States, will take place at 2:00 AM on Sunday, March 8th, advancing the time to 3:00 AM.

The implementation of DST in these border regions contrasts with the rest of Mexico, which abolished it in 2022. The continued practice aims to facilitate seamless commercial activities and cross-border interactions with neighboring U.S. states. While the change provides longer evening daylight, it also raises concerns about potential disruptions to individuals’ biological clocks and possible health implications.

Key Points:

  • Daylight Saving Time begins in border cities of Chihuahua, Coahuila, Nuevo León, and Tamaulipas at 2:00 AM on March 8, 2026.
  • The time will be advanced by one hour to align with the United States.
  • Mexico eliminated DST for most of the country in 2022, but retained it in border regions for economic and practical reasons.
  • The time change aims to synchronize activities with U.S. states, facilitating trade and cross-border interactions.
  • Some studies suggest potential negative health effects associated with the time change.

Key Takeaways:

  • Economic considerations continue to outweigh concerns about potential health impacts in the decision to maintain DST in border regions.
  • The divergence in timekeeping practices between border regions and the rest of Mexico highlights the unique economic relationship between these areas and the United States.
  • The decision to maintain DST reflects the importance of facilitating cross-border trade, labor, education, and people flow.
