In most parts of the United States, residents need to adjust their clocks twice a year: once when Daylight Saving Time begins and once when it ends.
Each year, Daylight Saving Time in the United States begins on the second Sunday of March. For 2024, this change occurred on Sunday, March 10, at 2:00 a.m., when clocks were set forward by one hour. But when does Daylight Saving Time end?
Daylight Saving Time in 2025
Daylight Saving Time ends annually on the first Sunday of November. In 2024, this will take place on Sunday, November 3, at 2:00 a.m. At this time, clocks will be set back by one hour, returning to standard time.
To summarize:
- Start of Daylight Saving Time 2024: Sunday, March 10, 2:00 a.m. (clocks forward one hour)
- End of Daylight Saving Time 2024: Sunday, November 3, 2:00 a.m. (clocks back one hour)
Ensure you adjust your clocks accordingly to stay on track with the time changes!
In most cases, people don’t need to worry about manually adjusting their clocks, as most electronic devices, like smartphones, automatically update the time at 2:00 a.m.
Daylight Saving Time in 2025

Areas in the USA That Do Not Change Their Clocks
Although most states in the United States have to adjust their clocks twice a year, certain regions do not observe Daylight Saving Time. This is because the Uniform Time Act of 1966 allows them to opt out of observing it.
The state of Hawaii and most of Arizona do not participate in Daylight Saving Time, so residents never need to change their clocks. Other US territories in the Pacific and the Caribbean, such as Puerto Rico, the Virgin Islands, the Northern Mariana Islands, Guam, and American Samoa, also maintain standard time year-round.
