Should We 'Heed the Science and Abolish Daylight Saving Time'? (msn.com) 252

Today much of the world honors an annual tradition: setting their clocks backwards by one hour. "I hope you enjoy it," writes Boston Globe Jeff Jacoby.

In an essay titled "Heed the science and abolish daylight saving time," Jacoby writes "I also hope this is the last year we have to go through this business of shifting our clocks ahead, and that by this time next year we'll be back on standard time for good." I am not a fan of daylight saving time, and if the polls are accurate, neither are most Americans. According to a 2019 survey by the Associated Press and the National Opinion Research Center, 71 percent of the public wants to put an end to the twice-yearly practice of changing clocks... Most of the rest of the world doesn't want it either. In Asia, Africa, and South America, it's virtually nonexistent. Most of Australia and many of the nations of the South Pacific eschew it, as do Russia and most of the former Soviet republics. The European Parliament voted by a large margin to end daylight saving time across the European Union, though whether to implement that change is left up to each EU member state...

The point of "saving" daylight was to save fuel: Congress believed that by shifting the clock so daylight extended later into the evening, the law would reduce demand for electricity and thereby conserve oil. But researchers attempting to measure the effects of clock-changing on energy savings have found them pretty elusive... But daylight saving time doesn't just fail to deliver the single most important benefit expected of it. It also generates a slew of harms. In the days following the onset of daylight time each March, there is a measurable increase in suicides, atrial fibrillation, strokes, and heart attacks. Workplace injuries climb. So do fatal car crashes and emergency room visits. There is even evidence that judges hand down harsher sentences. All of which helps explain the growing chorus of scientists calling for an end to daylight saving time. The public-health problems stem not just from the loss of an hour of sleep once a year but from the ongoing disruption to the human circadian clock...

We should no longer be thinking about "springing forward" and "falling back" in terms of personal preference or convenience but should be focusing instead on the proven degradation to human well-being. Scientists now understand vastly more about the workings and importance of circadian rhythm than they did when clock-shifting was instituted decades ago. There is a growing medical consensus that what we've been doing with our clocks each spring is unhealthy.

It's time to stop doing it.

      Ending DST is the wrong solution. Making it permanent is the best solution. Canadian provinces and US states can already opt out of DST. Unfortunately they aren't authorized to make it permanent. That's all we need is the federal legislation to authorize them to make the decision. Many if not most of them already want to, so authorize it and let them do the heavy lifting.

      But DST IS a routine, and a stupid and costly one.
      If you want to stir up life, you could suggest we have like a random number generator running every week, deciding a time zone for each area. And make it able to include funky time zones too, like the ones that have 30 or even 15 minute offsets. Now, that's fun!

    • P.S. personally I like DST, because it is fun to stir up life routines from time to time

      It used to matter to me, but now it doesn't. All my clocks adjust automatically. Today I didn't even notice it was DST until I read this article.

      ...which itself is only accurate if you ignore countries like Canada, Australia, Mongolia etc. which just by themselves make up about an eighth of the land area of the planet.

  • In Asia, Africa, and South America, it's virtually nonexistent.

    There is a reason for that: at low latitudes, near the equator, daylight hours remain pretty constant throughout the year. Only countries in far northern, or southern, latitudes have a large seasonal variation in daylight which, as the name suggests, is the argument behind "daylight-saving" - although of course, it does not really save any at all it just shifts it to a different local time.

      There is no need for it here at halfway to the north pole either.

      The whole thing reminds me of my friend that used to set his alarm clock's time a couple of minutes ahead so he'd get up on time. Of course, he knew it was ahead a little so he'd just hit snooze, and then set the alarm clock a few more minutes ahead the next day. This did not help him get up on time at all, but he kept doing it until it was like 30 minutes off.

  • I'm not going to invoke Betteridge here, because whether to keep or end DST can depend on **which part** of the science one listens to:

        Everyone using UTC time (or whatever other common time) would already be huge progress, yes.

  • Yes, no one, absolutely no one likes to re-set the clocks twice per year. Even people who like DST. So this is a non-argument.

    But people who say the don't like DST because they don't like setting their clocks, usually don't fully grasp the consequences of DST. And I'm sure they wouldn't like the sun coming up at 3am either. And I'd rather set my clocks twice per year than that.

    DST does NOT make the sun shine longer. Just later. That's also a hint to everyone suggesting DST all year round.

    Seriously. This isn't 'news'. The arguments aren't new. The counter-arguments aren't new. The fact that it is an emotional issue for everybody involved and not a logical one, but everybody claims their arguments are logical (well, they are reasonable, but irrational because we aren't agreeing on the premises), isn't new.

    Most Americans are against time changing, not against daylight saving time (summer time). What they rarely ask in these polls is if we want to stay on standard (winter time) or on summer time.

    So, like most, I want time changing to stop, no matter what. So that is not the issue. Almost all the annoyance and bad effects are do to changing time, not which time we keep. There are almost no positives.

    The point of "saving" daylight was to save fuel: Congress believed that by shifting the clock so daylight extended later into the evening, the law would reduce demand for electricity and thereby conserve oil. But researchers attempting to measure the effects of clock-changing on energy savings have found them pretty elusive...

    They found it not just elusive but somewhat counter-effective even back in the '60s. Maybe it saved a little lighting. But it cost more in air conditioning, with people home more in the hotter part of the day.

    But with the change from predominantly incandescent and fluorescent lighting to LEDs (about 10x savings over incandescent, 2.5x over fluorescent), lighting has become a much smaller part of the load. Meanwhile air conditioning and other energy-intensive loads have increased - with improvements in efficiency swamped by increased adoption. So loads and fuel costs now rise, rather than fall, with DST.

    Meanwhile the low cost (even unsubsidized) of photovoltaic generation and the rapid improvements in time-shifting energy storage technology are driving a shift from fuel-powered to renewable energy sources. The storage technology improvements are largely driven by the development of electric vehicles - which also enables a shift away from fuel-driven vehicles to battery powered or hybrid, charged by a mix of fuel-produced and renewable energy and/or with regenerative braking rather than pure fuel/brake propulsion.

    So fuel and its costs are becoming less of an issue - and will become even less as time goes on.

    So why are we bothering with this all-downside clock tweaking?
