It’s been over a hundred years since the U.S. first experimented with daylight saving time, yet the debate around it persists. While some are convinced it’s a beneficial shift, others argue that it’s unnecessary, disruptive, and even dangerous. And despite its name, daylight saving time may not “save” anything after all.
In recent years, there’s been a growing movement to end the biannual clock changes. For instance, the European Union has proposed putting an end to daylight saving time altogether. In the U.S., Florida’s “Sunshine Protection Act” aims to make daylight saving a permanent fixture in the state. If approved, Florida would effectively shift one time zone east, aligning with places like Nova Scotia instead of New York.
Questionable Origins and Expected Benefits
The original proponents of daylight saving believed it would save energy, provide fresher farm produce, and even reduce eye strain for workers. However, these promises were mostly wishful thinking. While legislators still tout the benefits of “extra sunshine,” the true impact on business and daily life is still unclear.
Coordinating Time for the Railroads
Before standardized time, people relied on the sun, leading to inconsistent timekeeping across towns. But as railroads expanded, the need for synchronized time became essential. In 1883, railroads created 24 time zones worldwide, which allowed for a more reliable schedule for arrivals and departures. This system stuck, keeping time simple—until daylight saving time arrived to complicate it once again.
World War I Spurs Daylight Saving
The first official experiment with daylight saving in the U.S. was tied to patriotism. When Congress passed the Calder Act in 1918, the rationale was that shifting light to later in the day would save energy for the war effort. However, this idea met significant resistance, especially from rural communities who felt it disrupted natural “sun time.” Within a year, the policy was repealed, though many cities continued observing it on their own.
Local Time Chaos
The repeal didn’t stop local governments from adopting their own daylight-saving practices, creating a chaotic time patchwork across the U.S. By 1965, each state, and sometimes individual cities followed different daylight-saving schedules. The result? Travelers might pass through multiple local time zones in just a short drive. The mess led to the Uniform Time Act of 1966, mandating six months each of standard and daylight saving time.
A Boon for Businesses – But Not for Energy Savings
Daylight saving has always boosted retail and recreation industries. Studies show that later sunsets encourage more people to engage in outdoor activities, from shopping to sports. For example, extending daylight saving by one month in 1986 generated millions in revenue for the golf industry. Even today, people tend to turn off their TVs and head outside during daylight saving time, leaving popular shows with lower ratings.
Energy Savings: The Great Myth
Despite the long-held belief that daylight saving conserves energy, studies show otherwise. In fact, daylight saving might even increase energy use, as people use more electricity at home and drive more to enjoy the extended daylight hours. Gasoline consumption rises, making daylight saving an ineffective and misleading substitute for true energy policies.
Florida’s Year-Round Daylight Saving: A Risky Experiment?
In 1974, President Nixon imposed year-round daylight saving as a reaction to an energy crisis. But the change led to unintended consequences, especially in Florida, where the delayed sunrise meant children were heading to school in the dark. Tragically, several traffic accidents occurred, sparking a backlash against the policy. Now, lawmakers in Florida are once again advocating for permanent daylight saving, despite these past lessons.
Daylight Saving: A Lesson in Policy Persistence
As daylight saving time reaches its centennial, it continues to spark debate. The initial vision of saving energy and boosting morale may not have panned out, but the enduring power of tradition—and a little extra evening sunlight—keeps it going. Whether the policy truly benefits modern society remains an open question, but for now, it seems the practice is here to stay.
