• •Al Jazeera reports that the United States remains divided on whether to adopt permanent standard time or daylight saving time.
• •Biannual clock changes in the US are currently mandated by the Uniform Time Act of 1966, excluding states like Hawaii and Arizona.
• •Proposed federal legislation to make daylight saving time permanent has repeatedly stalled in Congress due to conflicting regional interests.
• •The scientific community's stance on the health impacts of permanent time choices remains a point of contention that prevents legislative consensus.

The United States continues to oscillate between standard time and daylight saving time due to a long-standing failure to reach a federal legislative consensus. Unlike many international jurisdictions that have opted to abolish clock shifts, the US remains trapped by the 1966 Uniform Time Act. While proponents argue for the economic benefits of permanent daylight saving time, sleep researchers and health advocates frequently cite potential negative impacts on circadian rhythms. Whether the US can move toward a uniform standard remains uncertain, as regional differences in sunlight and industry preferences continue to stall progress in the House of Representatives.
