2 a.m., Sunday, Nov. 4, 2018
That time is coming again. Prepare yourself for an extra hour of sleep next weekend, when Daylight Saving Time ends early Sunday morning, Nov. 4, 2018. At 2 a.m. Colorado will "fall back," as it suddenly becomes 1 a.m. again.
Don't forget to set those pesky clocks on your stove, microwave and VCR (we still have these, right?), and in your car. Obviously, whatever you use as an alarm clock will be of paramount importance. Smartphones and computers can generally be counted on to adjust themselves, provided the automatic timekeeping settings haven't been disabled.
Why Daylight Saving Time? The further one is from the equator, the more imbalanced the length of daylight vs. nighttime becomes as the Earth moves around the sun and its angle changes.
Officially, it began in the U.S. to save on fuel during World War I. Public opinion was divided, though many businesses favored it because it meant workers had daylight left for shopping more days of the year; the film industry was opposed, though, because who wants to see a movie in a dark theater when it's bright outside still?
President George Bush in 2005 signed an energy bill that extended Daylight Saving Time by four weeks.
Colorado lawmakers have tried multiple times to pass bills that would either exempt the state from Daylight Saving Time, or keep it year-round. Studies have found the time changes can increase the risk of certain types of deaths, and increase the risk of automobile and other accidents.
