Clocks will be turned back one hour on Sunday, October 30, 2011 in most regions of Mexico as daylight saving time (DST) ends. The clocks will go back from 2am (02:00) to 1am (01:00) local time on October 30.
Most European countries will also switch from DST to standard time on Sunday, October 30, 2011.
Mexico – USA time difference
Mexico’s DST schedule ends early in the morning on the last Sunday of October every year.
This is one week earlier than the United States’ DST change, leading to a one-hour time difference between most of Mexico and the US for one week between October 30 and November 6, 2011.
2: Mexico’s Congress passed a law in December 2009, bringing the DST schedule observed by northern Mexico’s border cities to be in line with the United States' DST schedule. This affects the following areas:
- Tijuana & Playas de Rosarito
- Ciudad Juarez
- Ciudad Acuña
- Piedras Negras
- Nuevo Laredo
