Today on Truth Social, President Donald J. Trump announced that the Republican Party intends to eliminate Daylight Saving Time (DST), calling it “inconvenient and very costly to our Nation.” The post has reignited national debate about the twice-annual time change, sparking discussions about its origins, impact, and what it would take to do away with the practice altogether.

Daylight Saving Time was first implemented in the United States during World War I as a way to conserve fuel and energy by maximizing daylight hours. The practice was standardized nationwide with the Uniform Time Act of 1966, though states were given the option to opt-out. Today, Hawaii and most of Arizona, as well as U.S. territories like Puerto Rico and Guam, do not observe DST.
The idea has long been controversial. While proponents argue it saves energy and encourages outdoor activity during extended daylight, critics say its benefits are negligible in the modern era and that the disruptions to sleep and productivity are more harmful than helpful.
The call to end DST aligns with growing public sentiment. A 2022 survey by the Associated Press-NORC Center for Public Affairs Research found that nearly 60% of Americans want to eliminate the biannual clock changes. Supporters of abolishing DST argue that it can disrupt sleep patterns, lead to health issues, and cause workplace inefficiency. Additionally, studies have shown an increase in heart attacks and traffic accidents following the springtime shift.
