S. 582 – Sunshine Protection Act of 2023

AI-Generated Summary

Updated January 20, 2026 at 4:10 AM UTC

The Sunshine Protection Act of 2023 would make daylight‑saving time (DST) permanent throughout the United States, eliminating the seasonal clock change. It repeals the part of the Uniform Time Act that limits DST to a temporary period and adjusts related historic time‑keeping statutes. States that previously opted out of DST can keep their existing standard‑time arrangements if they choose.

Key Provisions

Repeals Section 3 of the Uniform Time Act of 1966, removing the temporary DST period.
Amends the Calder Act to shift the standard‑time offsets by one hour, effectively aligning the nation with permanent DST.
Allows any state or area that had previously exempted itself from DST to retain its prior standard‑time choice or adopt the new permanent DST schedule.
Updates related language to reference the new subsection for state exemptions.
