AI-Generated Summary

Updated February 7, 2026 at 11:56 PM UTC

The Sunshine Protection Act of 2021 would make daylight‑saving time permanent across the United States. It repeals the temporary daylight‑saving provision of the Uniform Time Act and changes the legal definition of standard time so the country stays on the advanced clock year‑round. States that have previously opted out of daylight‑saving time may keep their own standard time if they choose. The changes would take effect on November 5, 2023.

Key Provisions

  • Repeals the temporary daylight‑saving period in the Uniform Time Act of 1966.
  • Amends the 1918 Calder Act to shift the standard‑time offsets by one hour, effectively keeping the nation on daylight‑saving time permanently.
  • Allows states or areas that have exempted themselves from daylight‑saving time to retain their own standard time as they see fit.
  • Sets the effective date of the new permanent daylight‑saving time as November 5, 2023.
