This Sunday is November 3rd, the first Sunday in November, and that means the end of Daylight Saving Time and the beginning of Standard Time. That means we have to turn back the clock one hour throughout most of the U.S. (Arizona and Hawaii decline to change their clocks, and U.S. territories don’t either.) The good news: You’ll gain an hour of sleep this weekend. The bad news: It will be dark by the time most of us get out of work every day from now until March 8.
