The answer? During World War I, Germany shifted its clocks to save electricity: Wake people up an hour earlier, the sun feels like it sets an hour later, and you don’t need to turn on as many lights. The concept caught on around the world, including the United States, which first introduced daylight saving time in 1918 (although it didn’t become permanent in most of the country until nearly 50 years later).
But times have changed — and so have energy costs. In 2006, Indiana joined in on daylight saving time, leaving Hawaii and Arizona as the only states that don’t observe it. That created a “natural experiment,” says Yale University economics professor Matthew Kotchen, who studied data from before and after Indiana’s switch and discovered that energy use increased slightly after.
Kotchen’s other finding: “Everyone is confused about daylight saving time.” Many folks think it starts in the fall, which is when it ends. They’ll tell you it’s for farmers, who don’t care about time (animals don’t wear watches). Some even believe it extends sunlight, a trick that would require controlling the Earth’s rotation.
Back in that barbershop, the customers told Steube they were done adjusting clocks. When he went to work on the issue, he quickly learned that the majority of Floridians agree. But there’s a hitch. The state prefers year-round daylight saving time, not standard time, and that’s against U.S. law. So Congress would need to change the law.
Maybe senators and representatives will be swayed by what’s happening across the Atlantic Ocean, where Europe may soon abolish its twice-yearly clock changes. The European Commission, which represents 28 countries, recently asked for public comment on what it calls “summertime arrangements,” and 4.6 million people responded — 84 percent in favor of picking a time and sticking with it. (The majority were German!)
The European Parliament will vote by next spring, when clocks are slated to jump ahead possibly for the final time. Then it’s up to each country to decide whether to stay on summertime, or fall back in October to permanent wintertime.
It’s an easy choice for Sean Kelly, an Irish member of Parliament who’s opposed clock changes since childhood, when “falling back” made it too dark to play soccer after school. He’s already fantasizing about how he’ll celebrate next fall. In that last hour before sunset, Kelly vows, “I will go for an hour-long walk or cycle.”
