As a result of the October 26th, 2022, order from the Mexican Government, Daylight Saving Time (DST) in the United Mexican States will not be observed in 2023 calendar year. Only US-Mexico border parts of Chihuahua, Coahuila, Nuevo León, Tamaulipas, and the state of Baja California will continue the established DST schedule. This schedule started on Sunday, March 12, 2023 at 2:00 AM and will end on Sunday, November 5, 2023 at 2:00 AM.

Microsoft has released Windows Updates in support of these changes as part of the February 2023 Cumulative Update preview for Windows 10, versions 20H2, 21H2, and 22H2, as well as for Windows 11, version 21H2 and 22H2. All other supported Windows versions will receive the update as part of March 2023 monthly quality update available beginning March 14th. Please read Mexico 2023 time zone updates now available for additional details and resources.

When will this happen:
The new DST regulation in Mexico is in effect since October 26th, 2022. Starting March 12, 2023, most of the country did not change clocks, except for a limited list of US-Mexico border municipalities and the entire state of Baja California. This geographical selection will continue to follow the US-established DST schedule between March 12, 2023 and November 5, 2023.
