Put your timepieces on hold for an hour Sunday
Sir Isaac Newton didn’t know anything about shifting time, but his third law of motion might aptly describe a semi-annual manmade phenomenon: “For every action there is an equal and opposite reaction.”
In brief, it’s now time to undo what was done last spring, implementing “an equal and opposite reaction.” At 2 a.m. Sunday (earlier for those who don’t want to stay awake that long) Daylight Saving Time officially ends, and clocks should be set back one hour.
While the length of darkness and daylight won’t change much this weekend, daybreak and dusk will occur an hour earlier. Commuters will begin their daily drives under lighter conditions. Conversely, evening commutes will be under darker skies.
Most of the U.S. adopted the summer shift to Daylight Saving Time and will officially revert back this weekend. The exceptions are Arizona and Hawaii, American Samoa, Guam, Puerto Rico and the U.S. Virgin Islands, which don't observe Daylight Saving Time.
If you don’t want to wait until 2 a.m., feel free to reset your timepieces before retiring for the evening Saturday.
Whether you like or loath the semi-annual changes, you can blame/credit early American thinker Benjamin Franklin for conceiving it. According to National Geographic, Franklin considered the resource savings that could be achieved by spending more of our waking hours in daylight.
Most of the U.S. adopted the practice of shifting time with approval of the Uniform Time Act of 1966. It was implemented the following summer. Wikipedia provides a brief history:
