The Bill Passes the House. The Debate Resurfaces.

On July 14, 2026, the U.S. House of Representatives passed the Sunshine Protection Act by a vote of 308 to 117, advancing permanent daylight saving time further than it has gone in years. The bill represents a renewed push after the Senate passed a similar measure unanimously in 2022, only for it to stall in the House.

The bill now heads to the Senate. Supporters argue that eliminating the twice-yearly clock change would reduce sleep disruption, lower traffic accident rates, and stimulate evening economic activity. Critics point out that permanent daylight saving time would mean longer periods of winter darkness in the morning, with particular impact on northern states and early commuters.

The United States has been through this debate before — fifty years ago. That experiment lasted less than ten months.

An Oil Crisis Drove the Original Experiment

In October 1973, the Yom Kippur War erupted in the Middle East. The Organization of Arab Petroleum Exporting Countries (OAPEC) announced an oil embargo against Western nations supporting Israel. The United States bore the brunt. Gas station lines stretched for miles, odd-even rationing began across states, and heating oil ran short. Oil prices surged roughly 45 percent during the embargo — from about $3 per barrel to nearly $12.[1]

The Nixon administration declared an "energy emergency" and rolled out conservation measures, including lowering highway speed limits and cutting airline flights. One measure seemed elegantly simple: extend daylight saving time to year-round. The logic was straightforward — an extra hour of natural evening light meant people delayed turning on their lights, reducing electricity consumption.

On December 15, 1973, Nixon signed the Emergency Daylight Saving Time Energy Conservation Act (Public Law 93-182).[2] Beginning January 6, 1974, the entire United States entered permanent daylight saving time. The House passed it 311–88; the Senate 68–10 — a level of bipartisan support exceptionally rare in American legislative history.[3]

"Daylight saving time on a year-round basis will mean only a minimum of inconvenience and will involve equal participation by all."

First Workday: Sunrise at 8:27 a.m. in Washington

On the first workday after permanent daylight saving time took effect, sunrise in Washington, D.C. came at 8:27 a.m. Children headed out into the dark.

"It was jet black outside when my daughter was supposed to leave for school. Some of the children took flashlights with them."

— Florence Bauer, Springfield, Virginia, speaking to The Washington Post, January 7, 1974 [5]

Across the Eastern United States, winter sunrises had been pushed to 8 a.m. or later; in parts of the North, sunrise crept past 9:30 a.m. Within days of the law taking effect, accidents began to pile up:

DST expert and author of Seize the Daylight, David Prerau, noted that in Florida, eight children were killed on their way to school in the first two weeks of winter daylight saving time — compared with two the previous year — and "it became a big issue."[6] Florida's Commissioner of Education, Floyd T. Christian, submitted a memorandum to the State Board of Education on January 28, 1974, documenting how school districts had responded: 55 districts pushed back start times by 30 minutes to an hour, while 12 made no adjustments.[7]

"It's time to recognize that we may well have made a mistake."

— Senator Dick Clark of Iowa, congressional speech, January 28, 1974

Approval: 79% → 42% — But the Data Is More Nuanced

According to The New York Times, public approval plummeted from 79 percent in December 1973 to just 42 percent by February 1974.[8]

The data, however, told a more complicated story. The National Safety Council's February report showed pre-sunrise fatalities had risen from 19 to 20 compared with the previous year — a modest increase — while afternoon accidents fell as evening light improved. The Department of Transportation's research also confirmed that year-round daylight saving time reduced overall traffic accidents.[9]

Note: The debate over permanent daylight saving time involves genuine disagreement among researchers and policymakers. The American Academy of Sleep Medicine (AASM) and 20 other medical organizations support permanent standard time, citing circadian biology. Proponents of permanent daylight saving time cite benefits for evening activity, economic output, and the elimination of clock-change disruptions. Both positions are supported by research.

One structural factor that shaped the 1974 outcome was geographic variation: the United States spans a wide range of latitudes, and winter sunrise times differ dramatically by region. For Florida or Texas, a winter sunrise delayed to around 7 a.m. remained tolerable. For Minnesota, Maine, or Kansas, where winter sunrises already came around 8 a.m., an additional hour meant children would not see their first ray of sunlight until nearly 9 — by which time they were already in school.

Arguments for Permanent DST

  • More evening natural light
  • Eliminates clock-change sleep disruption
  • Fewer afternoon traffic accidents
  • Boosts evening economic activity
  • Ends the twice-yearly clock ritual

Arguments Against Permanent DST

  • Longer dark winter mornings
  • Safety concerns for children commuting
  • Northern states disproportionately affected
  • Sleep medicine community favors permanent standard time
  • 1974 experiment provides a cautionary precedent

American clocks fall back to standard time. The permanent DST experiment is officially over.

"Energy savings must be balanced against a majority of the public's distaste for the observance of Daylight Saving Time."

— Senate deliberations on H.R. 16102, 1974

The following spring, in 1975, the United States briefly resumed daylight saving time, but only through that autumn. Congress ultimately chose not to renew it, and the country returned to the traditional twice-yearly clock change — a practice that continues to this day.

1974

On that winter morning, the image of children walking to school by flashlight became the most concrete expression of a debate that had seemed abstract in December.

In July 2026, the House passed the Sunshine Protection Act 308–117. The bill now awaits the Senate.
