Sunrise shifts after daylight saving time begins, but permanent-fix debate remains split

Sunday at 6: 00 a. m. ET, daylight saving time had begun across most of the U. S., and sunrise arrived an hour later on the clock in places such as Boston. Still unresolved is whether the political and legal steps needed to change the system will succeed, and the next clarity point is any federal move that would let states keep daylight saving time year-round.

National Weather Service Boston example shows the Sunrise change immediately

Daylight saving time for 2026 started early Sunday, and most Americans effectively lost an hour of sleep overnight as clocks moved forward. The change happens at 2 a. m. local time, when the clock jumps to 3 a. m., creating a 23-hour day in most of the country.

In Boston, the immediate effect is visible in the clock-time shift of daylight. On Saturday, the day before the time change, sunrise in Boston was 6: 09 a. m. and sunset was 5: 41 p. m., based on National Weather Service times. On Sunday, after the clocks changed, sunrise was 7: 08 a. m. and sunset was 6: 42 p. m. —a direct illustration of how the switch moves an hour of daylight from the morning to the evening.

Only two states do not observe daylight saving time—Hawaii and Arizona—except for the Navajo Nation in the northeast part of Arizona. Several U. S. territories also do not change their clocks: American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the U. S. Virgin Islands.

U. S. Naval Observatory rules are set, but Congress and states remain divided

The second Sunday of March start date has been in place since 2007, and the U. S. Naval Observatory is described as the official source of time for the Defense Department. Yet the policy debate over whether to keep switching clocks or move to a permanent system remains unsettled.

At least 19 states have passed laws designed to let them stay on daylight saving time if the federal government allows it. That condition—federal permission—remains the key barrier, and any change depends on political action that, so far, has not succeeded because opinions about impacts are sharply divided.

Two competing outcomes are being argued, each with a different effect on morning light. Making daylight saving time permanent would mean the sun rises around 9 a. m. in Detroit for a period during the winter. Keeping standard time year-round would mean the sun could be up at 4: 11 a. m. in Seattle in June. Those are examples used in the debate, and they underscore why agreement has been difficult.

National Institute of Standards and Technology timeline sets the next fixed points

For now, the confirmed timeline is that daylight saving time is in effect for 238 days, as counted by the National Institute of Standards and Technology, a government agency that provides the official time for the U. S. The country will “fall back” to standard time at 2 a. m. local time on the first Sunday of November, which this year is Nov. 1.

The shift also lands ahead of the calendar start of spring: the vernal equinox is March 20. In the fall, the autumnal equinox is Sept. 22, and the return to standard time comes nearly six weeks later.

Evidence about benefits and harms is also part of what can influence policy—though the record described so far is mixed. The annual time change has not been found to be a significant source of decreasing energy consumption, and a 1974 Transportation Department finding cited minimal benefits for energy conservation, traffic safety and reducing violent crime. After the 2007 calendar change, the Energy Department found electricity consumption fell by 0. 03%. The time shift has also been associated with some negative health effects.

The next confirmed event that will move the story is the return to standard time on Sunday, Nov. 1, at 2: 00 a. m. local time. If the federal government acts to allow states to keep daylight saving time permanently, states with laws already passed are expected to be positioned to stop changing clocks on that schedule.
