Daylight saving time: Why it isn’t going away

5 fun facts about Daylight Saving Time clock change.

Daylight Saving Time is Sunday morning, which means the sun will set in Boston just after 4:30 p.m. for the next week, serving as a reminder that another winter will soon be upon us. Canadians in most parts of the country will be setting back their clocks this weekend, but a British Columbia man who says he is sick of all the springing forward and falling back wants to bring an end to the clock-changing tradition.Authorities advised using this time of year to partake in the semi-annual clock-changing exercise, which includes replacing batteries in smoke and carbon monoxide detectors along with emergency flashlights.

Here are some of the things—aside from changing the few manual clocks you still have lying around that won’t fix themselves—that you can do with an extra 60 minutes on your hands. Dieno runs a safety equipment company and says there are lots of studies that show that the time change affects people’s sleep, making them less productive and more accident-prone. “There’s an increase of accidents on the roads, there’s an increase of pedestrian accidents and there’s also an increase in workplace injuries,” he says. The good news for those who don’t want to live in darkness is that sunrise will move up nearly an hour — from 7:26 a.m. on Halloween to 6:27 a.m. on Nov. 1. 3. Having your fans run clockwise during the winter can save on energy costs—when the blades move in the opposite direction, they circulate warm air throughout the room according to Energy Star.

Though the brain is not a perfect timekeeper, research suggests people do have a sort of internal “clock” that helps them keep track of how much time is passing. In 2007, crime rates dropped by as much as seven percent in the days following the implementation of DST, according to an analysis done by Jennifer L. Many brain regions appear to be involved in this process, but activation in the insular cortex —located between the temporal lobe and the parietal and frontal lobes — may play an important role, according to a 2013 article in the journal Nature Reviews Neuroscience. With a potentially brutal New England winter and freezing temperatures on the way, it’s a good time to turn off outside water so that water in the pipes doesn’t freeze and cause them to burst.

More objective measures of timekeeping go way back: Ancient Egyptians divided the day into 12 hour-long segments, and used both astronomy and devices called water clocks to track the hours. Nevada seeks to follow the DST schedule year-round, which would enable residents of the state to avoid the inconvenience of having to switch their clocks twice a year. Other ancient timekeeping methods included sundials and candle clocks, which worked like water clocks except by melting wax rather than by dripping water. Other critics of DST, such as Michael Downing, professor of English at Tufts University and author of “Spring Foward: The Annual Madness of Daylight Savings,” also note that while DST was originally established to support the war effort, its largest supporter since 1915 is the Chamber of Commerce. “The Chamber understood that if you give workers more sunlight at the end of the day they’ll stop and shop on their way home,” said Downing in a radio interview. Mechanical clocks, first invented in the late 1200s, according to the University of Houston’s Engines of Our Ingenuity science program, are easier to mess with.

As lawmakers have pushed daylight saving time’s start earlier into spring and its end later into fall – the “fall back” weekend jumped from October to November in 2007 – we now observe DST for the vast majority of the year. “Today we have eight months of daylight saving and only four months of standard time,” Professor Downing said. “Can you tell me which time is the standard?” Congress passed a repeal, Wilson vetoed their bill, and Congress actually overrode the veto — something that’s happened only 110 times in U.S. history, according to Senate records.

In his book, Prerau tells of a Delaware man who got his draft number changed during the Vietnam War by pointing out that by official standard time, his birthday was a day earlier than officially recorded.
