WASHINGTON, July 14 (Reuters) – The U.S. House of Representatives overwhelmingly voted on Tuesday to pass a ‌bill making daylight saving time permanent and ending the twice-yearly practice of changing clocks that has been observed across most of the United States since the 1960s.

The 308-117 vote sends the bill to the Senate. If enacted, clocks would no longer ​return to standard time in November, though states could opt out of year-round daylight saving ​time.

Supporters say changing the clocks disrupts sleep, increases workplace injuries and contributes to more ⁠road accidents. They also argue that keeping clocks an hour ahead year-round would provide more evening daylight ​and boost economic activity during the winter months.

Critics say the change would mean the sun rises an hour ​later on winter mornings, leaving more children traveling to school and commuters heading to work before daylight.

President Donald Trump has repeatedly called for an end to the twice-yearly clock changes and strongly supports the measure.

The bill still faces opposition from ​Senator Tom Cotton, an Arkansas Republican, and others. Cotton has argued that permanent daylight saving time would ​result in very late winter sunrises and force children in many parts of the country to go to school in ‌darkness.

On ⁠Monday, House lawmakers rejected a request to vote on an alternative proposal that would have made standard time, rather than daylight saving time, permanent.

Airlines for America, a group representing major U.S. air carriers, raised concerns, saying the bill would “have considerable implications for aviation, including passenger disruption, crew and aircraft positioning, and domestic and ​international connectivity issues…. Any ​changes would need an ⁠implementation timeline that reflects these global complications.”

In May, the House Energy and Commerce Committee voted 48-1 in favor of the Sunshine Protection Act. The U.S. Senate ​voted unanimously in March 2022 to make daylight saving time permanent but the ​House never took ⁠up the measure in the face of opposition. Hawaii and Arizona do not observe daylight saving time.

The U.S. used year-round daylight saving time during World War Two and enacted it again in 1974 to reduce energy use. But it ⁠proved deeply ​unpopular and Congress repealed it later that year.

Democratic Representative Frank ​Pallone said on Tuesday that commuting and work habits have changed and far fewer school children walk to school. “It’s time to finally ​end the process of springing forward and falling back,” Pallone said.
