When Does Daylight Savings Time End In Your Area? Here's What To Know

It's that time of year again — school is back in session, you're breaking out pumpkins and fuzzy blankets for the transition to fall decor, and suddenly, a steamy bowl of soup sounds like it would hit the spot. The days are also getting a bit shorter, which means the end of Daylight Saving Time is right around the corner.

In 2025, Daylight Saving Time will end on November 2 at 2 a.m. local time for most — but not all — locations in the United States. It's autumn, when we "fall back," meaning the clocks will reset to 1 a.m. and you'll (hopefully) get to enjoy an extra hour of sleep as we enter Standard Time once again. The shift means that there will be more light in the early morning hours, but it will get dark earlier in the evening.

Thanks to the rise of the digital age, you probably don't have to manually set back as many clocks as you used to. Smart devices and high-tech kitchen appliances often automatically adjust to the time change, hopefully preventing you from any embarrassing time-related mix-ups during that first day. But keep in mind that many cars, wristwatches, large wall clocks, and appliances may require you to change the time.

Most of the country will be adjusting to the end of Daylight Saving Time on the first Sunday in November. However, there are a couple states and a few overseas territories that remain on Standard Time throughout the year. Their clocks won't change this fall or in the foreseeable future.

One of the states is Hawaii. The islands are close enough to the equator that sunrise and sunset times don't fluctuate as much throughout the year. Without drastic changes to the length of the day, there's no reason for the tropical state to change clocks.

Most of Arizona, aside from the area in the northeastern part of the state that is part of the Navajo Nation, also doesn't shift clocks between Daylight Saving Time and Standard Time. Arizona opted for the exemption thanks to its hot climate. In the spring, when we "spring forward" into the longer days of Daylight Saving Time, Arizona residents would be out longer in the sun's heat and shoulder higher energy costs thanks to running air conditioning through the longer days. To give its residents a break from the heat, the state chose to remain in a fixed time all year long back in the 1960s. Guam, Puerto Rico, U.S. Virgin Islands, and Northern Mariana Islands also remain on Standard Time year-round. 

Even though most climates across the country don't match those of Hawaii and Arizona, the time shift can be disruptive to daily life in lots of ways. Both the loss and the gain of an hour can disrupt our natural circadian rhythms — and some researchers point out that has higher stakes than just an extra yawn or two. Parents have long noted that the switch can mess with bedtimes or wake times for kids and make them cranky. Mood disturbances, stock market volatilities, and even fatal traffic accidents have all been shown to rise in the days following the transition between standard and saving times. These consequences of time changes have pushed many sleep experts to advocate for a permanent standard time.

Many Americans agree with the experts. More than half of the country would prefer to do away with biannual time changes. Others disagree, preferring some light in their morning throughout the often-dismal winter months. Congress is divided, too. In recent years, lawmakers have floated the Sunshine Protection Act, which would keep the country in a fixed time all year. It didn't turn into law, however, so it's safe to say that unless you're in Hawaii or Arizona, remember to switch your clocks this November — and probably beyond.
