Sunshine Protection Act of 2023

S 582 (Sunshine Protection Act of 2023) would make daylight saving time permanent across the United States, eliminating the need to change clocks twice yearly. It repeals the 1966 law requiring seasonal time changes and adjusts time zone offset language to reflect permanent daylight saving time (e.g., changing "4 hours" to "3 hours" in time zone rules). The bill directly affects all states and territories currently observing daylight saving time, with a specific exemption for states or areas that had already opted out of the Uniform Time Act before this bill's enactment. Key provisions include permanently adopting daylight saving time as standard time and allowing previously exempt states to maintain their existing time practices. This is a procedural change to federal timekeeping law, not a new policy affecting other areas.
