Daylight Savings Ends 2026: What Nov. 1 Means for Hawaii, Arizona

Most Americans now have an extra hour of evening daylight and one less hour of sleep, a shift that will shape family routines, energy use and commute light through the fall. Updated on March 8, 2026, 6: 00 am ET, daylight saving time started early Sunday when clocks jumped from 2 a. m. to 3 a. m. local time, a change visible in National Weather Service sunrise and sunset times and setting the stage for Daylight Savings Ends 2026 on Nov. 1.

Boston sunrise and sunset numbers show the immediate change

Boston illustrates the immediate consequence: the day before the change, sunrise was at 6: 09 a. m. and sunset at 5: 41 p. m.; after clocks moved forward, sunrise shifted to 7: 08 a. m. and sunset to 6: 42 p. m. These concrete hour-by-hour shifts mean more light in the evening and darker mornings for that region.

Most of the U. S. experienced the clock jump at 2 a. m., when time advanced to 3 a. m., a single, discrete moment that produced the overnight loss of sleep for millions and altered morning light for commuters and parents alike.

Daylight Savings Ends 2026 and communities that never change clocks: Hawaii, Arizona

Daylight Savings Ends 2026 will arrive on the first Sunday in November, which this year falls on Nov. 1, when most Americans will “fall back” to standard time at 2 a. m. local time. That reversal restores the hour lost in March and shifts daylight back toward mornings for the winter months.

Not every part of the country observes the switch. Hawaii and Arizona (except for the Navajo Nation) do not change clocks, and the territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the U. S. Virgin Islands also remain on a steady time year-round. Families in those places avoid the twice-yearly scheduling disruption.

Parents in regions that do observe the change reported tangible effects: losing one hour of sleep can mean a week or more of disrupted schedules, meltdowns and extra wakeups for young children. One parent who moved to Hawaii described crossing the time change off the list as a relief for her family’s sleep routines.

U. S. Naval Observatory, the National Institute of Standards and Technology and the timeline that set it

The current start date — the second Sunday of March — has been in place since 2007, a schedule tied to U. S. timekeeping authorities including the U. S. Naval Observatory. The National Institute of Standards and Technology, the government agency that provides the official time for the U. S., notes daylight saving time will be in effect for 238 days this year.

Historical shifts shaped today’s calendar: for two decades before 2007 the start date was the first Sunday of April, and before 1987 the Uniform Time Act had set the start as the last Sunday of April. An earlier national experiment in 1974 tried year-round daylight saving time beginning the first Sunday of January but reverted later that year and adjusted again in 1975.

Federal reviews have repeatedly questioned the net benefits. The Transportation Department found minimal gains for energy conservation, traffic safety and crime during the 1974 experiment, and after the 2007 change the Energy Department measured a small 0. 03% fall in electricity consumption.

What could reverse or accelerate these calendar effects is straightforward: if daylight saving time remains in effect for 238 days this year, the country will return to standard time at 2 a. m. local time on Nov. 1. If that schedule holds, families and businesses should expect morning light to increase and evenings to shorten by that date.
