Daylight Savings Time ends this Sunday night, so turn your clocks back one hour before going to bed, or you will be late for work, yoga or the gym, or whatever you have planned for Monday morning. This will be the last time that Mexico adheres to Daylight Savings Time, as the Mexican congress voted almost unanimously against it this year. The only exceptions are the state of Northern Baja, Sonora, in the north and Quintana Roo in the South, due to their business ties with the U.S. border and Central America.
