01 · The brief
Plain-English summaryWhat this bill actually does

The bill (Sunshine Protection Act of 2025) repeals the temporary provision of the Uniform Time Act and amends the 1918 Calder Act to advance U.S. standard time zone offsets by one hour, effectively making daylight saving time permanent nationwide. It also provides that States or areas that previously exempted themselves from daylight saving time may choose either the new advanced standard time or their prior standard time.

Why people may split

Health concerns (liberal) vs convenience/economic gains (centrist, conservative).

Watch point

Relative to its intended legislative type, this bill is a focused statutory change that clearly amends specific provisions of existing timekeeping laws to make daylight saving time permanent and to preserve existing state exemptions.
