This legislation, known as the "Sunshine Protection Act of 2025," proposes to make daylight saving time permanent across the United States. It achieves this by repealing the section of the Uniform Time Act of 1966 that established a temporary period for daylight saving time, thereby eliminating the annual practice of changing clocks. The bill further amends existing law to advance the standard time in most time zones by one hour, effectively making the current daylight saving time the new year-round standard time. States or areas that had previously exempted themselves from daylight saving time would retain the option to either adopt this new permanent standard time or maintain their previous standard time as it existed before the Act's enactment.
