Overview

  • At 2:00 a.m. on Sunday, November 2, clocks in most of the United States move back to 1:00 a.m., returning to standard time.
  • No nationwide clock change occurs in Mexico, but more than 30 northern border municipalities will also set clocks back to stay aligned with adjacent U.S. cities.
  • Border localities set to change include Tijuana and Mexicali in Baja California, Juárez in Chihuahua, Piedras Negras in Coahuila, Anáhuac in Nuevo León, and Nuevo Laredo, Reynosa and Matamoros in Tamaulipas.
  • NIST advises that many modern clocks and phones update automatically via the WWVB signal, while older devices may require manual adjustment on Saturday night or a software update.
  • U.S. time rules remain under federal oversight by the DOT with DST extended since 2007, as debate continues over health impacts highlighted by a Stanford analysis favoring permanent standard time and a presidential call to adopt permanent summer time that has not altered current law.
