Daylight saving time for 2026 officially began early Sunday morning, and most Americans felt it — losing a full hour of sleep overnight as clocks sprang forward. The annual tradition, observed on the second Sunday of March, doesn’t create more daylight. It simply reshuffles it.
By moving clocks forward one hour, an hour of morning daylight is effectively transferred to the evening. The difference is noticeable almost immediately. On Saturday, Boston’s sunrise came at 6:09 a.m. with sunset at 5:41 p.m. By Sunday, the sun didn’t rise until 7:08 a.m. — but it also stayed up until 6:42 p.m. Evenings got brighter. Mornings, temporarily, got darker.
When Daylight Saving Time Started and Why the Date Keeps Shifting
This year, clocks moved forward on Sunday, March 8, at 2 a.m. local time — jumping instantly to 3 a.m. That second-Sunday-of-March rule has been in place since 2007, but it wasn’t always that way.
Here’s how the start date has evolved over the decades
- Before 1987 — The Uniform Time Act of 1966 placed the start on the last Sunday of April
- 1987–2006 — The start date shifted earlier to the first Sunday of April
- 2007–present — The Energy Policy Act moved it up again to the second Sunday of March
- 1974 experiment — During the energy crisis, Congress tried year-round daylight saving time starting the first Sunday of January, but the country reverted to standard time that October
- 1975 — Daylight saving time resumed on the last Sunday of February before returning to an April start
The 1970s experiment was short-lived and largely unpopular, especially in winter months when dark mornings made the change feel more burdensome than beneficial.
Daylight Saving Time History and Its Murky Benefits
Daylight saving time was first introduced in the U.S. in 1918 as a wartime fuel conservation measure during World War I. It was revived during World War II under similar reasoning, with officials also citing national security. Since the 1960s, the time change has been a consistent annual fixture — but its practical benefits have always been debated.
A 1974 Transportation Department review found minimal impact on energy conservation, traffic safety, or violent crime reduction. More recently, after the 2007 date change took effect, the Energy Department found electricity consumption dropped by just 0.03% — a negligible figure.
Beyond energy, research has linked the springtime clock shift to a range of negative health effects, including disrupted sleep patterns, increased risk of heart events, and reduced productivity in the days following the change. Lawmakers continue debating whether the biannual clock change makes sense.
Daylight Saving Time 2026 End Date and Key Facts
Daylight saving time won’t last forever — at least not this cycle. Here are the key dates and figures to keep in mind
- Start date — Sunday, March 8, 2026 at 2 a.m.
- End date — Sunday, November 1, 2026 at 2 a.m. (clocks fall back one hour)
- Duration — Daylight saving time will be in effect for 238 days
- Spring equinox — March 20 (daylight saving time begins before actual spring)
- Fall equinox — September 22 (the country will be nearly six weeks into fall before clocks fall back)
Which States and Territories Skip Daylight Saving Time
Not everyone participates. Two U.S. states opt out entirely
- Hawaii — Does not observe daylight saving time
- Arizona — Does not observe daylight saving time, with one exception: the Navajo Nation in the northeastern part of the state does follow the time change
Several U.S. territories also keep their clocks fixed year-round
- American Samoa
- Guam
- Northern Mariana Islands
- Puerto Rico
- U.S. Virgin Islands
As for your phone — if it’s set to update automatically, it already made the switch on its own overnight. No manual adjustment needed.
