I was going to write a post about Daylight Saving Time, specifically the many myths that get thrown around by people trying to explain it. I think the fact that almost no one understands why we do it is one of the best arguments for why we shouldn’t do it at all. Let alone the problems the switch causes: Heart problems, road accidents and mood changes are associated with the DST time change. But while I was searching for a good image to attach to such a post, I found this Buzzfeed article and includes a section that hits all the notes I wanted to:
In 1905, a British architect named William Willett invented daylight saving time. Willett was out for his regular early-morning horse ride when it he noticed that 1) it was rather light outside, and 2) he was the only one up. Like Franklin, he thought this was a waste of perfectly good sunlight. And it ~dawned~ on him that instead of getting everyone up earlier by blasting cannons, they could simply shift their clocks forward to take better advantage of that sweet daylight. So, in 1907 Willett published a pamphlet outlining his formal proposal. He suggested that people turn their clocks forward 20 minutes every Sunday in April at 2 a.m. (And then they would set the clocks back by 20 minutes every Sunday in September.) He argued that this would get people outside and exercising, and that it would save on electricity, gas, candles, etc. (He also estimated it would save $200 million in today’s dollars. This was…again, a wild exaggeration.) A member of parliament, Richard Pearce, heard about Willett’s idea and was into it; he introduced Pearce’s Daylight Saving Bill to the House of Commons in February of 1908. The idea of changing the clocks four times in a month didn’t go over well, and the bill was eventually revised so that the clocks would be set forward one hour at 2 a.m. on the third Sunday in April (and then set back in September).
The bill was endorsed by merchants, banks, railroad companies, and the guy who created Sherlock Holmes, but was opposed by most astronomers and scientists. And one newspaper wrote “that if a man were going to a 7:00 dinner, under the new arrangement of daylight he would appear on the streets of London in evening dress at 5:40, which would shake the British Empire to its foundations.”
You know who else opposed the bill? FARMERS. They argued from the start that they couldn’t perform their operations at a different time — for example, they couldn’t harvest grass for hay while it was still wet with dew, and the dew wasn’t going to disappear earlier just because the clock had changed. And there were other activities that they couldn’t do until temperatures dropped after the sun went down. Basically, they hated DST from its inception.
Despite the association with farmers, daylight saving time actually came to the United States thanks to business owners (and war)
If you feel like garbage this week, you can direct your curses toward Marcus A. Marks, a clothing manufacturer; A. Lincoln Filene, a department store owner; and Robert Garland, a Pittsburgh industrialist. These three were very pro-DST, and were able to get labor organizations on board, along with the US Chamber of Commerce, the president of the National League of Baseball Clubs, and other prominent business owners. Even President Woodrow Wilson wrote a letter expressing his support for their efforts.
Less than two weeks after the US entered WWI, a daylight saving bill was introduced in Congress. It was heavily opposed by farmers, and also railroad companies, who were concerned about anything that could mess with the standard time zones (which had only recently become A Thing — a story for another day), and who said that 1,698,818 (!!) clocks and watches along their routes would have to be changed if DST were implemented. Because the fewest trains were running at 2 a.m., that became the proposed hour for the change-over. And because the most coal was consumed in March and October in the States, the bill was expanded to include those two months. On March 19, 1918, daylight saving time was signed into law in the United States, and took effect on March 31 of that year.

The energy consumption savings argument was difficult to back up with numbers in 1918. The energy consumption argument at least had some slight possibility of being correct in 1918, when the vast majority of energy use was in factories, retail businesses, and the like. Residential energy use was limited to cooking, heating, and providing light usually with oil- or gas-burning lamps.
But in 2018 the argument doesn’t hold up. For instance, residential energy use thanks to all our computers, TVs, sound systems, game systems, refrigerators, microwaves, et cetera is a larger fraction of the total national energy consumption. And the amount of that home energy consumed for lighting is much smaller than all those other things. Also, a much larger proportion of businesses run 24 hours a day than did back then. Setting clocks forward or back has negligible impact on how much energy is used per day on a 24-hour business.
What I’m saying is, there isn’t much reason to justify the effort, the impacts on people’s health, and other costs of this twice annual fiddling with the clock.
Besides, I’ve always agreed with the one reaction, usually attributed to an elderly man on a Native American Reservation after first getting an explanation of Daylight Saving Time: “Only a fool would think you could cut a foot off the top of a blanket, then sew it to the bottom to get a longer blanket.”
