Sunshine Protection Act of 2025

This bill would make daylight saving time permanent across the United States by repealing the current rule that requires switching back to standard time in the fall. It directly affects all states and territories, though it preserves exemptions for areas like Arizona and Hawaii that currently skip daylight saving time. Key provisions include adjusting time zone calculations in historical laws (e.g., changing "4 hours" to "3 hours" in time zone references) and allowing states that already opted out of daylight saving time to maintain their preferred standard time. The bill does not create new policies but changes the legal framework to end seasonal time changes.
