Overview
- The House approved the Sunshine Protection Act in a 308–117 vote that would lock clocks on daylight saving time year‑round and let states opt out before the law takes effect.
- The bill now goes to the U.S. Senate, where its fate is uncertain because some senators, including Tom Cotton, have said they will oppose year‑round daylight saving time.
- President Donald Trump has publicly backed the measure and the White House signaled it would sign the bill if it reaches his desk.
- Major medical and sleep organizations favor permanent standard time instead, arguing it better aligns with human circadian rhythms and reduces health and safety risks tied to darker winter mornings.
- If enacted, reports project the last clock change would occur in fall 2027 and many states that prepassed laws to adopt permanent DST could implement the change then.
