Time to Fall Back – Daylight Savings officially ends at 2:00 AM on the first Sunday in November. So Saturday night (November 5th) before you go to bed, set your clocks back one hour and enjoy the extra rest. The U.S. remains on Standard Time until the second Sunday in March. While in the U.S. each time zone switches at a different time, the European Union all changes at the same time – 1:00 am Universal Time (Greenwich Mean Time). Don’t forget to change the batteries in your smoke detectors as well; keeping them fresh, can keep you alive.
