President-elect Donald Trump said Friday that Republicans will attempt to eliminate daylight saving time, the twice-yearly practice of moving clocks to adjust for the seasons. 

Under daylight saving time, clocks “spring forward” an hour in March to provide more daylight into the evening, then “fall back” an hour in November to return to standard time.

“The Republican Party will use its best efforts to eliminate Daylight Saving Time, which has a small but strong constituency, but shouldn’t!” Mr. Trump posted on social media. “Daylight Saving Time is inconvenient, and very costly to our Nation.”

Proposals in Congress have generally focused on the opposite of what Mr. Trump is suggesting, making daylight saving time permanent.

The Sunshine Protection Act, a bill Florida lawmakers have long pushed to make daylight saving time permanent, has not gone anywhere this Congress. The Senate passed the bill two years ago in the previous session by unanimous consent, but it stalled in the House.

GOP Sen. Marco Rubio of Florida, Mr. Trump’s nominee to serve as secretary of state, is the lead Senate sponsor of the bill, which has bipartisan support.

Rep. Greg Steube, another Florida Republican, launched a discharge petition on the House version of the Sunshine Protection Act last month to try to force floor action. Discharge petitions need 218 signatures to succeed. His has only seven.

While there has been no equivalent legislative push to make standard time permanent, Sen. Tom Cotton of Arkansas, the incoming Republican Conference chair, appears ready to take it on.

“Congress once made Daylight Saving Time permanent. It was so unpopular that Congress repealed it less than a year later,” Mr. Cotton posted on X. “The only sensible and durable way to stop the biannual time change is to make Standard Time permanent. I will work on this issue with @realDonaldTrump.”
