As daylight saving time approaches, millions across the United States prepare to set their clocks forward one hour at 2 a.m. on Sunday, March 8. This annual shift marks the beginning of longer evenings, as daylight extends later into the day, though it also means losing an hour of sleep. Clocks will revert back on November 1.
While many individuals look forward to the extra hour of daylight, the practice of changing clocks twice a year has sparked considerable debate. Some lawmakers are advocating for an end to daylight saving time, questioning its benefits and considering its impact on public health.
The history of daylight saving time dates back to 1918, initially implemented to conserve fuel during World War I. It saw a revival in World War II and was adopted more broadly during the 1970s energy crisis. In 1966, the Uniform Time Act established a federal standard, although participation is voluntary for states. Hawaii and most of Arizona, along with U.S. territories like American Samoa and Puerto Rico, do not observe the time change.
Globally, the observance of daylight saving time varies significantly. While much of Canada and parts of Mexico near the U.S. engage in the practice, countries in Europe mostly follow suit, excluding Iceland, Russia, and Belarus. Some nations in the Middle East and South America, including Israel and Chile, also participate, but there is little to no observance in Africa and Asia.
The push to abolish or modify daylight saving time is gaining traction, driven by concerns regarding its adverse effects on health. Studies indicate that the transition can increase the risks of strokes and heart attacks while significantly disrupting sleep patterns, especially for teenagers.
Recently, legislative efforts at both state and federal levels have sought to address these concerns. Bills advocating for permanent daylight saving time and those favoring standard time are being considered across the country. Notably, the Sunshine Protection Act, aimed at making daylight saving time permanent nationwide, has been reintroduced but remains stalled in Congress. Additionally, a new proposal dubbed the Daylight Act of 2026 has emerged, suggesting a compromise of a 30-minute permanent shift from standard time.
As discussions about the future of daylight saving time continue, many hope for a resolution that balances the benefits of longer daylight with the need for healthy sleep patterns.
