The twice-a-year clock change is still around, for now. Donald Trump has reignited the debate over Daylight Saving Time (DST). In 2019, he voiced support for permanently adopting DST, aligning with growing calls from state legislatures nationwide to eliminate the twice-yearly clock changes. Now he says the Republican Party will use its best efforts to eliminate it.

Daylight Saving Time (DST) is a controversial practice that involves adjusting clocks twice a year. While intended to save energy and make better use of daylight, the economic impact tells a different story.

Today, most states observe DST, but Arizona and Hawaii remain exceptions. These states have opted out entirely, providing a glimpse into life without clock adjustments. As dissatisfaction with DST grows, more states and lawmakers are advocating for change.

A Costly Adjustment

Studies estimate that shifting clocks back and forth to DST costs the U.S. economy at least $430 million annually. Some reports peg the figure even higher, suggesting economic losses could reach $1.7 billion. These costs come from workplace productivity declines, sleep disturbances, and even an uptick in workplace and traffic accidents.

Switching clocks affects people’s circadian rhythms, leading to drowsiness, stress, and decreased productivity. In office settings, 'cyberloafing,' time spent browsing unrelated content online, spikes after the biannual time change.

Workplace Risks and Productivity

For industries like mining and construction, the stakes are higher. DST transitions lead to increased workplace injuries. Fatigue and misalignment of body clocks create hazardous working conditions, which cost companies money in lost labor and medical expenses.

Does DST Save Energy?

DST’s origins trace back to Germany during World War I as a way to conserve electricity. However, modern studies show mixed results. A study from Indiana revealed energy use actually increased due to more heating in the mornings and cooling in the evenings. While the original purpose of DST may no longer be relevant, the economic toll continues to to be an inefficiency embedded in society.

Health Consequences Have Their Toll

The health impacts of DST go beyond sleep disruption; rapidly shifting the population's sleep schedule is associated with higher rates of heart attacks, increased stress, and cardiovascular strain. These health issues not only affect individuals but also burden healthcare systems and employers with higher absenteeism and lower output.

Could We Finally See DST End?

Back in 2022, the Senate unanimously passed a bill in 2022 to make DST permanent. Spearheaded by Senator Marco Rubio, the proposal dubbed the “Sunshine Protection Act,” sought to 'lock the clock' and eliminate the biannual time shifts. However, the bill stalled in the House and has yet to be revisited. With Trump's declaration ahead of his second term, we could finally see an end to the practice.
