Overview
- The U.S. House voted 308-117 to pass the Sunshine Protection Act, which would end the twice-yearly clock changes and set daylight saving time year-round.
- The measure, which the House approved on Tuesday, July 14, allows states to opt out and keep standard time but must still clear the Senate and be signed by President Donald Trump to become law.
- Major medical and sleep organizations oppose permanent daylight saving time, saying it misaligns circadian rhythms and raises risks to health and safety, and some lawmakers including Sen. Tom Cotton have warned of darker winter mornings for children and commuters.
- About 19 states have prepassed laws to switch to year-round daylight saving time if Congress authorizes it, and business groups from tourism to retail and golf have lobbied for the extra evening daylight as an economic benefit.
- Despite the House vote and White House support, the bill’s future is uncertain because the Senate must act, earlier versions stalled after initial approval in 2022, and a competing proposal seeks permanent standard time.
