In brief
Trump's proposal renews the debate over the long-standing clock-changing practice, with advocates arguing about its effects on health, safety, and economic efficiency.
Former President Donald Trump has taken to his platform Truth Social to share his intent to abolish daylight saving time (DST), labeling it "very costly" and "inconvenient" for Americans. This announcement has reignited discussions around the biannual clock adjustments, which affect a significant portion of the global population, including many countries in Europe.Currently observed in approximately one-third of nations worldwide, including the United States, DST involves advancing the clock by one hour in spring and retarding it in autumn to maximize the use of daylight. Despite the tradition, numerous citizens in the US have voiced their opposition to DST over the years. Proponents of standard time argue it promotes better health, enabling improved sleep patterns with more morning light and sufficient darkness in the evenings. This perspective highlights the disorienting effects of clock changes on sleep schedules.On the other hand, a faction advocates for making DST permanent. They point to the potential benefits of brighter evenings, which could result in lower crime rates, energy savings, and enhanced safety on roads for individuals commuting after work or school.Trump's stance echoes previous efforts to reform DST. In 2022, a bill aimed at making daylight saving time permanent passed the Senate but was ultimately sidelined, failing to make its way to President Joe Biden. Republican Senator Marco Rubio championed the Sunshine Protection Act, claiming studies indicated that a shift to permanent DST could bolster economic outcomes. Notably, Rubio has been named by Trump as his choice for secretary of state in the incoming administration.Seasonal clock changes first began in the United States during World War I to preserve fuel. Although initially unwelcomed by farmers, the practice was reintroduced during World War II and established permanently in 1966, with states holding the option to refrain from participating. Currently, Hawaii and most regions of Arizona do not observe daylight saving time.Research conducted by Joan Costa-i-Font from the London School of Economics highlights several negative impacts of DST on sleep, physical well-being, and overall mental health. In financial terms, her findings suggest that eliminating DST could enhance economic productivity by €754 ($792; £627) per capita annually.Countries such as Mexico and Jordan have abolished daylight saving time in recent years, while others like Turkey and Russia opted for a permanent DST. A recent Monmouth University Poll revealed that approximately two-thirds of Americans are in favor of making daylight saving time a permanent practice moving forward.
