Daylight Saving Time 2026: US Start and End Dates

In 2026, daylight saving time (DST) in the United States begins on March 8 and ends on November 1. The transition occurs at 2 a.m. local time in every state that observes DST, with the exception of Arizona (excluding the Navajo Nation) and Hawaii, which do not participate. These dates are set by federal law and are consistent each year, so residents can plan accordingly for the spring “spring forward” and fall “fall back” adjustments.

The two US daylight saving time dates in 2026

The federal DST schedule for 2026 establishes two specific dates for all participating states. On Sunday, March 8, clocks are set forward one hour at 2 a.m., moving from standard time to daylight time. This change takes effect at the local time of each state, meaning that in the Eastern Time Zone the shift occurs at 2 a.m. Eastern Standard Time, while in the Pacific Time Zone it occurs at 2 a.m. Pacific Standard Time. The second transition occurs on Sunday, November 1, when clocks are set back one hour at 2 a.m., returning to standard time. Again, the 2 a.m. reference is local to each state’s time zone. These dates are identical to those used in previous years, as the Uniform Time Act and subsequent federal regulations mandate the second Sunday in March and the first Sunday in November for DST transitions. The consistency of these dates allows businesses, schools, and travelers to coordinate schedules across the country without confusion.

What happens at 2 a.m. on March 8

At 2 a.m. local time on March 8, 2026, every state that observes daylight saving time will advance its clocks by one hour. This means that the hour from 2 a.m. to 3 a.m. simply does not occur; the clock jumps from 1:59 a.m. to 2:00 a.m. daylight time. The practical effect is a loss of one hour of sleep for most people, but it also extends evening daylight by an hour, which can benefit outdoor activities, reduce energy consumption, and align business hours with daylight. For transportation and commerce, the shift requires adjustments to schedules, including flights, trains, and public transit. In the financial sector, trading platforms must account for the missing hour to maintain accurate time stamps. Because the change is uniform across the United States, interstate coordination is straightforward, though local businesses may need to update operating hours and employee schedules to reflect the new time.

What happens at 2 a.m. on November 1

On November 1, 2026, at 2 a.m. local time, most of the United States will transition from daylight saving time (DST) back to standard time. The clocks are set back one hour, so the hour between 1 a.m. and 2 a.m. repeats. This means that the day will contain 25 hours. The change is coordinated across all participating states, territories, and the District of Columbia, ensuring a uniform shift for transportation schedules, broadcast programming, and federal operations. The federal government, through the Department of Transportation, publishes a detailed timetable that aligns all federal agencies with the new standard time. For businesses and schools, this adjustment affects operating hours, meeting schedules, and payroll calculations that rely on timekeeping systems. The 25‑hour day also provides an extra hour of daylight in the evening, which can influence energy consumption patterns and outdoor activities. The change is mandated by the Uniform Time Act of 1966, amended in 2005 to extend DST to the end of 2026.

Who does not change clocks on those dates

Certain jurisdictions in the United States do not observe daylight saving time and therefore do not adjust their clocks on the November 1 transition. The most notable example is the state of Arizona, excluding the Navajo Nation, which remains on Mountain Standard Time year‑round. Additionally, the U.S. territories of Puerto Rico, Guam, the U.S. Virgin Islands, and American Samoa do not observe DST, maintaining Atlantic Standard Time, Chamorro Standard Time, Atlantic Standard Time, and Samoa Standard Time respectively throughout the year. These regions follow a consistent time standard, eliminating the need for biannual clock changes. As a result, residents and businesses in these areas experience no shift in local time on either the spring or fall transitions. This uniformity simplifies scheduling across time zones for entities that interact with these territories, as there is no need to account for a one‑hour shift during the DST transition periods.

How to confirm the correct local time zone

The first step in knowing when daylight saving time (DST) begins and ends in 2026 is to verify the time zone that applies to your specific location. The United States is divided into six primary time zones—Eastern, Central, Mountain, Pacific, Alaska, and Hawaii-Aleutian—each with its own DST rules. Some states and territories, such as Arizona (except the Navajo Nation) and Hawaii, do not observe DST at all. Within states that do observe DST, individual counties or municipalities may have different rules if they have adopted special legislation. For example, certain counties in Oregon and Washington have opted out of DST, while the rest of the state follows the federal schedule. To confirm your local zone, consult the U.S. Department of Transportation’s official time zone map or use a reputable online time‑zone converter that allows you to input your city or ZIP code. Once you have identified the correct zone, you can apply the 2026 DST schedule specific to that zone.

Common 2026 calendar mistakes including November 2 references

A frequent error in 2026 calendars is the assumption that the fall transition will occur on November 2. In reality, daylight saving time ends on November 1, 2026, at 2 a.m. local time in all zones that observe DST. The clocks are set back one hour, so 2 a.m. becomes 1 a.m., effectively creating a 25‑hour day. Because the change happens early in the morning, many people overlook the adjustment and schedule appointments for 2 a.m. on November 1, only to find the time has already rolled back. Another common mistake is confusing the start date in March. DST begins on March 8, 2026, at 2 a.m., when clocks move forward to 3 a.m., creating a 23‑hour day. Some calendars mistakenly list March 9 as the start date, which is the first full day of DST. To avoid these pitfalls, always double‑check the official federal notice that confirms March 8 and November 1 as the transition days for 2026, and adjust any recurring events accordingly.
