Highlights

The House voted 308-117 Tuesday to make daylight saving time permanent across the country, a result that would leave Arizona, which has not changed its clocks since 1968, in the unusual position of being aligned with the rest of the nation for the first time in nearly six decades, at least during summer months.

The bill, the Sunshine Protection Act, passed on a bipartisan basis, according to Cronkite News reporter Kyle Sekenski. States could opt out and choose permanent standard time instead, a provision that would allow Arizona to maintain its current arrangement.

Arizona's nine-member delegation split 5-4 against the measure. All three Arizona Democrats opposed it: Reps. Greg Stanton and Yassamin Ansari of Phoenix and Adelita Grijalva of Tucson. GOP Reps. Paul Gosar of Bullhead City and Andy Biggs of Gilbert also voted no. Supporting the bill were Republican Reps. Abe Hamadeh of Scottsdale, David Schweikert of Fountain Hills, Juan Ciscomani of Tucson, and Eli Crane of Oro Valley.

Arizona has been on Mountain Standard Time since 1968, which is why Phoenix and Los Angeles share the same clock during summer. The state adopted the permanent standard time posture to reduce cooling costs and allow evening activities to start earlier during its hot summers. The Navajo Nation, which controls a large portion of northeastern Arizona, does observe daylight saving time.

President Donald Trump has publicly backed the measure. After a House committee approved the bill 48-1 in May, Trump wrote on Truth Social that ending the clock change would be a win and that the country would go "with the far more popular alternative, Saving Daylight, which gives you a longer, brighter Day."

Why does this matter for Arizona property owners and businesses?

If the Senate passes the bill and Arizona opts out to remain on permanent standard time, the practical effect for Scottsdale residents and businesses is minimal, the state's clocks would not change. If Arizona were to align with the new federal standard, summer evenings would gain an additional hour of daylight, shifting the calculus for outdoor dining, golf tee times, and evening events at venues across the Valley.

The bill now goes to the Senate. No vote date has been announced.
