Some clocks in your house will change themselves. The oven clock, the car dashboard, and the watch in your drawer probably will not. This coming Sunday is the end of daylight saving time, and if you have been searching for the exact moment, here it is: daylight saving time 2026 ends at 2:00 a.m. local time on Sunday, November 1. At that moment, clocks fall back to 1:00 a.m. and that hour plays out a second time.

In Google Trends data for the US over the past 7 days, related searches for the seed term "daylight saving time" included "what is the status of federal efforts to make daylight saving time permanent?" (Breakout), "daylight saving time end date" (+300%), "daylight saving date" (+70%), and "daylight saving time date" (+60%) among rising terms. A rising percentage shows growth compared with the previous period, and "Breakout" means very large growth. Among top terms, "daylight saving time 2026" led with a score of 100, followed by "daylight saving time end" (66), "end of daylight saving time" (33), "daylight saving time change" (20), "what is daylight saving time" (16), and "when does daylight saving time end" (9). Top scores are relative interest, scaled so the most popular term in the set equals 100; they are not search counts.

What is daylight saving time?

Daylight saving time is the period of the year when clocks are set one hour ahead of standard time. The National Institute of Standards and Technology (NIST), which runs the federal time and frequency division, describes it simply: clocks move one hour ahead at the start of daylight saving time and back one hour at the end, which shifts daylight from the morning to the evening.

The two transition days are uneven. Per NIST, in spring the clock skips from 2 a.m. straight to 3 a.m., so that day has one less hour. In fall, 2 a.m. becomes 1 a.m. and the hour repeats, so that day has an extra hour.

Daylight saving time 2026: the start and end dates

The federal rule is written into the Uniform Time Act of 1966 at 15 U.S.C. 260a. As amended, the statute says daylight time begins at "2 o'clock antemeridian on the second Sunday of March" and ends at 2 o'clock antemeridian on the first Sunday of November.

For this year, NIST lists the daylight saving time date range as March 8, 2026 at 2 a.m. to November 1, 2026 at 2 a.m., local time. Applying the same second-Sunday rule, the next start falls on March 14, 2027.

NIST also notes that under the current rules daylight saving time lasts 238 days, or about 65% of the year. So the daylight saving time end date is not the start of the "normal" season in any numeric sense. Standard time is now the shorter of the two.

How the dates were set: a short history

The calendar you live with today is the result of more than a century of federal changes. The Congressional Research Service (CRS), the research arm of Congress inside the Library of Congress, traces the main steps in its report "Daylight Saving Time" (order code 98-99):

• 1918: Congress passed "An Act to preserve daylight and provide standard time for the United States," and daylight saving time began on March 31, 1918.
• After World War I: Per CRS, the idea was unpopular, and Congress abolished daylight saving time after the war, overriding a presidential veto.
• 1942 to 1945: CRS reports that year-round daylight saving time, called "War Time," began on February 9, 1942 and ended in September 1945.
• 1966: The Uniform Time Act set clocks ahead at 2:00 a.m. on the last Sunday in April and back on the last Sunday in October, per CRS. States could exempt themselves only if the entire state did so.
• 1974 to 1975: During the 1973 oil embargo, CRS reports, Congress enacted a trial of year-round daylight saving time that ran from January 6, 1974 to April 27, 1975.
• 1986: An amendment moved the start to the first Sunday in April, with the end still in October, per CRS.
• 2005: According to NIST, the Energy Policy Act of 2005 set the current schedule, which took effect in 2007, the first change in more than 20 years.

Every daylight saving time change on that list came from Congress. That pattern matters for the permanent-time debate further down.

Who oversees the clock, and who opts out

The US Department of Transportation (DOT) oversees the nation's time zones. DOT explains that the job landed there because time standards matter to so many modes of transportation, and that the official list of time zones sits in its regulations at 49 CFR part 71.

Under the Uniform Time Act, a state can exempt itself from daylight saving time by state law. DOT is clear about the catch: if a state chooses to observe daylight saving time, it must begin and end on the federally mandated dates. The statute (15 U.S.C. 260a) spells out what an exemption means: the whole state, including its political subdivisions, stays on standard time for that period. A state that spans two time zones may exempt the entire state or only the part in one zone.

Who skips it today? NIST lists Hawaii, American Samoa, Guam, Puerto Rico, and the Virgin Islands. Arizona does not observe it either, with one exception: the Navajo Indian Reservation, which does. DOT's list also includes the Northern Mariana Islands. CRS reports that Arizona was the first state to exempt itself, in 1968.

So in most of Arizona and in Hawaii, the end of daylight saving time does not move the clock at all.

Saving or savings? The vocabulary

NIST and DOT both title their pages "Daylight Saving Time," singular. The statute talks about "daylight time." Yet the official title of the current House bill on the subject reads "To make daylight savings time permanent," with an s. Both forms show up even in federal documents, so either one will get you to the right answer in a search bar.

The legal phrase "2 o'clock antemeridian" is worth a second look too. Antemeridian is the long form of a.m. (before midday), and postmeridian is p.m. Breaking a word into its Latin parts is the fastest way to remember it, the same approach we use in our explainer what does sublingual mean.

Permanent daylight saving time: where the federal bills stand

The proposal most people have heard of is the Sunshine Protection Act. Here is the record, from the Government Publishing Office's GovInfo bill texts:

• 2022: S. 623 in the 117th Congress, the Sunshine Protection Act of 2021, "Passed the Senate March 15, 2022," per the engrossed text on GovInfo. It did not become law in that Congress.
• 2026: H.R. 139 in the 119th Congress, titled the Sunshine Protection Act of 2025, carries the line "Passed the House of Representatives July 14, 2026." GovInfo's record shows it was received in the Senate and referred to the Committee on Commerce, Science, and Transportation on July 15, 2026.

As of the GovInfo record we checked on October 26, 2026, that Senate referral is the latest action listed. The bill has not been enacted, which is why clocks still fall back on November 1.

What would it do? Per the GovInfo text, H.R. 139 would repeal section 3 of the Uniform Time Act of 1966 (15 U.S.C. 260a), the section that creates the seasonal switch, and adjust the standard time offsets in 15 U.S.C. 261 instead.

Our take

We think the clock debate is easier to follow once you separate three things: the rule (two Sundays a year, fixed by statute), the referee (DOT), and the proposals (bills that are not law until both chambers pass them and they are signed). Most confusion comes from mixing up a vote with a law.

We also think the primary text beats a headline. The GovInfo bill pages say plainly what passed and when.

Why we carry it at PRSPR

A turn of the calendar is a good occasion for a different kind of check: reading the labels in your cupboard for what they say about formats, counts, and measures. The Seasonal Wellness Stack is four separate products, each with its own label:

• FLORÉ Probiotic: capsules, with a label count of 30 capsules.
• Chelated Zinc + Elderberry: an alcohol free liquid in a 4 fl oz (118 ml) bottle, with directions measured in teaspoons (5 ml).
• Vitamin D3 + K2: liquid drops in a 1 fl oz (30 ml) bottle.
• Magnesium Glycinate: capsules, with a label count of 120 capsules.

That is two capsule formats, one measured liquid, and one dropper bottle in a single set. If a teaspoon-based direction ever has you converting units, our guide to how many mL in a teaspoon walks through it. The stack is priced at $149.99, which the listing compares with $190.33 for the four purchased individually, a difference of $40.34. Each product is made in a GMP-certified facility and third-party batch tested. You can compare it with our other sets in Bundles.
