U.S. House Passes Bill to Make Daylight Saving Time Permanent

The U.S. House of Representatives passed the Sunshine Protection Act on July 14, 2026, with a vote of 308–117, moving to make daylight saving time (DST) permanent across the nation ^[1][2]. The legislation seeks to end the practice of changing clocks twice a year, a move that has garnered both support and opposition ^[1][3].

Supporters of the bill argue that eliminating clock changes could reduce sleep disruption, workplace injuries, and road accidents. They also suggest that more evening daylight could boost economic activity during the winter months ^[1][4]. Proponents, including Rep. Gus Bilirakis (R‑Fla.), emphasize benefits to tourism and the predictability of daylight hours ^[5].

Opponents, however, caution that permanent DST would result in darker winter mornings, potentially increasing hazards for children going to school and commuters traveling before sunrise ^[1][3]. Rep. Mary Gay Scanlon (D‑Pa.) has expressed concerns about these safety risks ^[5].

Analyses estimate that the biannual clock changes cost the U.S. economy approximately $672 million annually in metropolitan areas due to increased heart attacks, strokes, workplace accidents, and traffic incidents ^[6]. However, studies indicate that energy savings from DST are minimal or negligible, with some research showing increased energy use in certain regions ^[6][7].

Health and sleep experts, including the American Medical Association and the American Academy of Sleep Medicine, recommend permanent standard time over permanent DST. They cite better alignment with human circadian biology and lower health risks as key reasons ^[6]. A Stanford study from 2025 modeled health outcomes, finding that permanent standard time could reduce obesity by 2.6 million cases and strokes by 300,000 cases compared to permanent DST or biannual switching ^[8].

Conversely, a meta-analysis by Rutgers researchers found that permanent DST could prevent approximately 171 pedestrian fatalities per year, representing a 13% reduction ^[9]. Congressional testimony in late 2025 noted that permanent DST could benefit industries such as retail, restaurants, hospitality, and outdoor recreation by providing more evening daylight. However, it could also harm productivity due to misalignment with cognitive function and increased absenteeism ^[10].

What Is Known

The Sunshine Protection Act has passed the U.S. House and aims to make DST permanent, eliminating the need for biannual clock changes ^[1][2]. Supporters highlight potential reductions in accidents and economic benefits, while opponents raise safety concerns about darker mornings ^[1][3].

What Remains Unclear

The long-term effects of permanent DST on energy consumption and health remain debated, with studies showing mixed results ^[6][7]. The potential economic impact on various industries and overall productivity is also uncertain ^[10].
