Daylight Saving Time:
Couple of facts about DST: It’s Saving Time, not Savings Time. Nevertheless, many people feel the word savings (with an ‘s’) flows better, and “Daylight Savings Time” is also in common usage, and can be found in dictionaries. In the European Union, everybody sets their clocks ahead a couple of weeks from now on Mar 28. This can be a real pain if you’re traveling, by the way, and get caught in between.
Daylight Saving Time is not observed: in Hawaii, Guam, Puerto Rico, American Samoa, the Virgin Islands, and most of the state of Arizona (although not the Navajo Indian Reservation, which does observe). The Navajo Nation participates in the Daylight Saving Time policy due to its large size and location in three states.
Many fire departments encourage people to change the battery in your smoke detector when you change their clocks. A startling statistic: more than 90 percent of homes in the United States have smoke detectors, but one-third are estimated to have worn-out or missing batteries.
Does resetting the clocks really save energy? Maybe, maybe not. People tend to waste several hours of natural light each day. Most of us wake up well after the sun rises and go to sleep long after it sets. If we spent more waking hours when the sun is out, we wouldn’t need to use as much electricity to illuminate our surroundings.
At least that’s the theory. Of course, there are trade-offs. When you set your clocks forward, you exchange morning daylight for a later sunset. Later sunsets tend to get people out of the house more in the evenings, which could lead to an increase in driving (and gasoline use) and a reduction in the use of household appliances.
And a study last year showed during the summer months in Daylight Saving Time, people tended to turn on their A/C earlier because they got home earlier, hence a net loss of energy.
And if daylight time extended too far into the winter, more people would wake up before sunrise and turn on the lights. Government research from the 1970s suggests that extended daylight-saving time produces a modest but significant energy savings of about 1 percent.
Why isn’t it observed in Arizona, Hawaii and the U-S territories? Weather. They stay on standard time all year because if you’ve spent any time in the sweltering summer sun in those regions you can understand why residents don’t need another hour of sunlight. But, if you live in, say, Bullhead City, AZ, but work in Needles, CA, sometimes you’re on track, sometimes you’re a hour off.
