Heart attacks increase 24 percent in the week after the U.S. It wreaks havoc with people’s sleep cycles. Avoiding clock switches improves sleepĬritics of DST are correct about one thing: The biannual clock switch is bad for health and welfare. in 1973, which helped combat the effect of OPEC’s oil embargo. Similarly, DST resulted in 150,000 barrels of oil saved by the U.S. Officials at the California Energy Commission estimated that 3.4 percent of California’s winter energy usage could be saved by moving to year-round DST. This rationale motivated some in California to recommend permanent DST a decade ago, when the state experienced recurrent electricity shortages and rolling brown-outs. Under standard time, the sun rises earlier, reducing morning energy consumption, but only half of Americans are awake to be able to use the sun. Having more sun in the evening requires not just less electricity to provide lighting, but reduces the amount of oil and gas required to heat homes and businesses when people need that energy most. But a considerable portion of the population is still asleep at sunrise, resulting in significantly less demand for energy then. Virtually everyone in our society is awake and using energy in the early evening hours when the sun sets. When the sun is out later in the evening, peak energy loads are reduced. Many people don’t know that the original justification for the creation of DST was to save energy, initially during World War I and II and then later during the 1973 OPEC oil crisis. Crime rates are lower by 30 percent in the morning to afternoon hours, even when those morning hours occur before sunrise, when it’s still dark.Ī 2013 British study found that improved lighting in the evening hours could reduce the crime rate by up to 20 percent. This is especially true for crimes by juveniles, which peak in the after-school and early evening hours.Ĭriminals strongly prefer to do their work in the darkness of evening and night. Moving sunlight into the evening hours has a far greater impact on the prevention of crime than it does in the morning. imposed year-round standard time.ĭarkness is also a friend of crime. The opposite effect would occur if the U.S. Standard time has precisely the opposite impact, by moving sunlight into the morning.Ī meta-study by Rutgers researchers demonstrated that 343 lives per year could be saved by moving to year-round DST. Fatal vehicle-on-pedestrian crashes increase threefold when the sun goes down.ĭST brings an extra hour of sunlight into the evening to mitigate those risks. The evening rush hour is twice as fatal as the morning for various reasons: Far more people are on the road, more alcohol is in drivers’ bloodstreams, people are hurrying to get home and more children are enjoying outdoor, unsupervised play. Since 2007, all provinces, territories, and locations in Canada using DST follow the same start and end dates as the United States.Simply put, darkness kills – and darkness in the evening is far deadlier than darkness in the morning. From March 8, 2020, Yukon made DST permanent. Most of the province does not observe DST, except for some locations, including Creighton and Denare Beach. These include Chetwynd, Creston, Dawson Creek, Fort Nelson, and Fort St. For example, while British Columbia uses DST, some locations in the province do not. As a result, there are some locations don't follow the DST schedule of their in provinces and territories. It is up to the legislation in each municipality in Canada to decide on the use of DST.

The cities of Winnipeg and Brandon in Manitoba did so on April 24, 1916. On April 23, 1914, Regina in Saskatchewan implemented DST. Other locations in Canada soon followed suit. On July 1, 1908, the residents of Port Arthur, Ontario, today's Thunder Bay, turned their clocks forward by 1 hour to start the world's first DST period. Previous time with no Daylight Saving Time was 1913.Canada has observed DST for 111 years between 19 (DST in at least one location).Canada first observed Daylight Saving Time in 1908.(13 in total, 8 where all observe DST, 1 which doesn't observe DST, 4 with parts on DST)īritish Columbia (east, northeast, southeast) See table below.ĭST in Provinces and Territories in Canada Blanc-Sablon), Southampton Island, and some areas in British Columbia don't use DST and stay on standard time all year.
