Understanding Daylight Saving Time in the United States 2026
August 18, 2026 6 min read Daylight Saving TimeIn 2026, Daylight Saving Time (DST) in the United States begins on Sunday, March 8 at 2:00 AM, when clocks spring forward, and ends on Sunday, November 1 at 2:00 AM, when clocks fall back. This schedule applies to most of the country, although some regions do not participate.
As remote work continues to grow, understanding DST transitions is crucial for coordinating meetings and avoiding scheduling errors across different states and timezones.
The Rules of DST in 2026
When Do Clocks Change?
Under the Uniform Time Act, most of the United States observes DST. The changes occur on the second Sunday in March and the first Sunday in November.
Spring Forward: On Sunday, March 8, 2026, at 2:00 AM, clocks move forward to 3:00 AM. This means you lose an hour of sleep, but you gain more evening daylight.
Fall Back: On Sunday, November 1, 2026, at 2:00 AM, clocks move backward to 1:00 AM. This returns the country to Standard Time, giving you an extra hour of sleep but resulting in earlier sunsets.
Which States Do Not Observe DST?
While most of the country changes its clocks, two states remain on Standard Time all year round:
- Arizona: With the exception of the Navajo Nation, Arizona does not observe DST. The extreme heat makes evening daylight less desirable during the summer.
- Hawaii: Located near the equator, Hawaii experiences relatively consistent daylight hours year-round, making DST unnecessary.
Additionally, several US territories, including Puerto Rico, the US Virgin Islands, American Samoa, and Guam, do not observe DST.
US Time Zones in Summer vs Winter
Because the United States spans multiple timezones, the time differences between regions can be confusing during the transition periods. Here is how the major timezones shift between Standard Time and DST:
| Region | Standard Time (Winter) | DST (Summer) |
|---|---|---|
| Eastern Time | EST (UTC-5) | EDT (UTC-4) |
| Central Time | CST (UTC-6) | CDT (UTC-5) |
| Mountain Time (Most) | MST (UTC-7) | MDT (UTC-6) |
| Pacific Time | PST (UTC-8) | PDT (UTC-7) |
| Arizona (Most) | MST (UTC-7) | MST (UTC-7) |
| Hawaii | HST (UTC-10) | HST (UTC-10) |
Impact on Remote Scheduling
TheWeek of Misalignment
When the US changes its clocks in March and November, it does not always happen on the same days as other countries. For example, the European Union typically changes clocks on the last Sundays of March and October.
This creates a period of misalignment. Between the second Sunday in March and the last Sunday in March, the time difference between New York and London is 4 hours (instead of the usual 5 hours). Similarly, between the last Sunday in October and the first Sunday in November, the time difference shifts again.
💡 Pro Tip: Use tools like the New York to London time converter to automatically adjust for these temporary changes and ensure your meeting times are accurate year-round.
How to Handle the Transition
To avoid missed meetings or confusing your remote team, follow these best practices during the transition weeks:
- Always specify the timezone when scheduling meetings (e.g., 2:00 PM EST vs. 2:00 PM EDT).
- Update your calendar software to ensure it automatically handles DST transitions.
- Double-check the local time in non-observing regions like Arizona and Hawaii before calling.
- Use world clock tools to visualize the time differences during the misalignment weeks.
History of US DST
The concept of Daylight Saving Time was first widely implemented during World War I, with Germany introducing it in 1916 to conserve coal. The United States adopted DST shortly after, but the practice was largely abandoned after the war.
DST was reintroduced in the US during World War II and again in the 1970s during the oil crisis. The current schedule, established by the Energy Policy Act of 2005, mandates that DST begin on the second Sunday in March and end on the first Sunday in November.
While the debate over the necessity of DST continues, the current rules remain in effect for 2026.
