A couple of days ago, Casey Liss took a break from arguing about temperature scales to tweak me about the recent passage of the Sunshine Protection Act by the House. The Act would make Daylight Saving Time permanent, something Casey knows I disapprove of. A similar bill passed the Senate a few years ago, and Donald Trump has said he will sign this one, so there’s a decent chance it’ll become law. Let’s see what will happen if it does.
Like many people, I was all ready to abolish DST until 2013, when I read Drang’s article advocating for the twice-yearly ritual of clock changing. I was converted.
Five years ago, the Albertan government asked voters whether we should “adopt year-round Daylight Saving Time, which is summer hours”. A bare majority, 50.2%, voted against it. So, of course, our government has adopted permanent DST, and we will not be turning our clocks back this November. This aligns with the practices of our neighbouring provinces.
The United States at least has the advantage of a large population living fairly far south. On the shortest day of the year, Los Angeles still sees nearly 10 hours of daylight and over 14 on the longest day. In somewhere as far north as Calgary, the difference in daylight hours is far greater — from under 8 hours in December to over 16 in June. That means the effects of permanent DST are highly acute. The sun will not rise here before 8:00 am from October 15 through February 8, with the latest sunrises at 9:39 am for several days in a row.
Theory is different from reality and perhaps my mind will be changed if it is still daylight after 5:00 pm on the shortest days of the year. I look forward to that. But this has been tried before — unsuccessfully — and I question why this time would be any different.
