5 fun facts about Daylight Saving Time clock change.

With daylight saving time (DST) ending early Sunday, so too will arrive the yearly suggestion that DST is not a good use of, well, time – and that it was a bogus idea to start with. The Firemen’s Association of the State of New York is urging residents to use the time change as a reminder to put a new battery in smoke and carbon monoxide detectors and make sure they are in working order.

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. 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. 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. So why have states throughout the Southwest expressed interest in bills that would allow them to make modifications to the DST schedule, or even eliminate it entirely? “The end result that we’re seeking is to have the sun set later during the winter months, as well as not messing up everyone’s schedule twice a year, as it often does,” said Assemblyman Chris Edwards of Nevada at a hearing this spring. 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.
