Love it or hate it, this weekend is when we steal an hour of daylight from the evenings and add it to the mornings.

Sunday, Nov. 1, at 2 a.m. is when we move our clocks BACK one hour, shifting clocks from Daylight Saving Time to Standard Time.

The good news: We add an hour to the weekend (one we’ll give back on March 13). But for many people the change is another reminder that winter is near, with the sun starting to sett before many Puget Sound region residents leave the office for home.

Fun Facts About the Time Change:

* Benjamin Franklin was an early booster of Daylight Saving, though it was just one of the many ideas he dabbled with in a long career of invention. He never actually pushed for its adoption.

* The United States (and most of the rest of the world) didn’t begin observing DST until after World War I.

* Prior to 2007, DST was observed from the first Sunday in April to the last Sunday in October.

* Arizona is the only state in the continental U.S. that does not observe DST. Half the year the state is in the Pacific Time Zone, and the other half in Mountain Time.

* Indiana was once like Arizona, but in 2005 the state joined DST. Prior to that year, some counties in the state observed DST but most didn’t.

* Hawaii, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas do not observe DST.

* The U.S. Dept. of Transportation is the official keeper of DST, per a law passed by Congress in 1966. One argument for DST is that fewer accidents happen during daylight hours, so extending mornings (in winters) and evening (in summers) daylight results in a slight reduction in automobile accidents.

* Uniform time zones were first created in the United States by the railroad industry, which needed standardized local times to set schedules.

* Daylight Saving Time saves energy — a little. According to a 2008 Dept. of Energy study, U.S. electricity use was decreased by 0.5% for each day of the extended Daylight Saving Time, resulting in a savings of 0.03% for the year as a whole. The savings are small in percentage terms, but in absolute terms, they added up to 1.3 billion kilowatt-hours, enough to power about 122,000 average U.S. homes for a year. These savings come in the summer months of DST, not the Standard Time months we are about to enter.

* Fire departments nationwide urge you to make a habit of changing the batteries in home smoke alarms on the same weekend the clocks change.
