Every spring and every fall, as we “spring ahead” or “fall back,” people all around the country ask, “So am I gaining an hour or losing one?” It seems there is always confusion. And then there’s the question of why we do this at all. Why don’t we just leave the clocks alone and keep to “standard” time? Wouldn’t it just be easier? Well, get ready because it’s changing this November 4th.
I’ve always had some vague notion of the how and why we change our clocks, but I thought it had a much more recent history. I also thought it had to do with kids getting out of school and helping with farm work or something. I can’t tell you where I got that. You may already know it, but Daylight Saving Time (DST) is used to save energy and make better use of daylight. It was first used in 1908 in Thunder Bay, Canada. Many say the idea was actually conceived by Benjamin Franklin. Yep, our Ben, considered the “Father of Electricity.” According to timeanddate.com, however,
“Many sources also credit Benjamin Franklin with being the first to suggest seasonal time change. However, the idea voiced by the American inventor and politician in 1784 can hardly be described as fundamental for the development of modern DST. After all, it did not even involve turning the clocks. In a letter to the editor of the Journal of Paris, which was entitled “An Economical Project for Diminishing the Cost of Light”, Franklin simply suggested that Parisians could economize candle usage by getting people out of bed earlier in the morning. What’s more: Franklin meant it as a joke.”
The U.S. is one of about seventy countries around the world that use Daylight Saving (not SavingS) Time. Not every state in the country subscribes to it though. The Energy Policy Act of 2005 gives every state or territory the right to opt out of using DST. For the U.S. and its territories, Daylight Saving Time is NOT observed in Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands, the Commonwealth of Northern Mariana Islands, and Arizona. The Navajo Nation participates in the Daylight Saving Time policy, even in Arizona, due to its large size and location in three states. Florida wants to have Daylight Saving Time year-round and Governor Rick Scott has signed off on a bill, the “Sunshine Protection Act,” asking congress to make it happen.
So, remember noticing a time change in the time change? I do. All of a sudden, the spring change came earlier and the fall change came later. The Energy Policy Act of 2005 was signed into law on August 8, 2005 and it changed DST dates.
The Energy Policy Act extended the yearly Daylight Saving Time (DST) period in the United States by several weeks.
- The beginning of DST was moved from the first Sunday of April to the second Sunday of March.
- The end of DST was moved from the last Sunday of October to the first Sunday in November.
The law came into effect on March 1, 2007, and the new DST schedule was first applied on March 11 of the same year.
Some pros and cons of DST (Again, from timeanddate.com,):
Pro: Longer Evenings
Changing the clocks does not create extra daylight, but it causes the Sun to rise and set at a later time by the clock. So, when we spring forward an hour in spring, we add 1 hour of natural daylight to our afternoon schedule.
- Proponents of DST argue that longer evenings motivate people to get out of the house. The extra hour of daylight can be used for outdoor recreation like golf, soccer, baseball, running, etc. That way, DST may counteract the sedentary lifestyle of modern living.
- The tourism industry profits from brighter evenings. Longer nights give people more time to go shopping, to restaurants, or other events, boosting the local economy.
Con: Doesn’t Save Energy
A century ago, when DST was introduced, more daylight was a good thing because it meant less use of artificial light, helping to save energy. Modern society, with its computers, TV-screens, and air conditioning units uses more energy, no matter if the Sun is up or not. Today, the amount of energy saved from DST is negligible.
Pro: Less Artificial Light
One of the aims of DST is to make sure that people’s active hours coincide with daylight hours so that less artificial light is needed. This makes less sense close to the equator where the amount of daylight does not vary much in a year or near the poles where the difference between winter and summer daylight hours is very large.
However, at latitudes between these extremes, adjusting daily routines to the shifting day length during summer may indeed help to save energy. A German analysis of 44 studies on energy use and DST found a positive relationship between latitude and energy savings.
Con: Can Make People Sick
Changing the time, even if it is only by 1 hour, disrupts our body clocks or circadian rhythm. For most people, the resulting tiredness is simply an inconvenience. For some, however, the time change can have more serious consequences.
Pro: Lighter = Safer
Safety is a good argument for keeping the lighter evenings of DST.
Con: Costs Money
It is hard to determine the economic cost of the collective tiredness caused by DST, but studies have found that there is a decrease in productivity after the spring transition.
- The City of New York invested 1.5 million US dollars in a dusk and darkness safety campaign for the DST change for the fall of 2016.
- There is an extra cost in building DST support into computer systems and keeping them maintained, as well as manually changing clocks.
The debate over DST is ongoing. I figure, we made up “time” anyway, so, if we want to change it to suit us, why not? The sun will rise when she’s ready and set the same way.
