Daylight Saving Time 2021: When Does the Time Change?

When Does Daylight Saving Time Begin This Year?

March 2, 2021

Daylight Saving Time begins on Sunday, March 14, 2021, at 2:00 A.M.  On Saturday evening, our clocks need to “spring forward” one hour. See details about the history of “saving daylight” and why we still observe DST today. Plus, let us know what you think!

What Is Daylight Saving Time?

Daylight Saving Time (DST) is the practice of moving the clocks forward one hour from Standard Time during the summer months, and changing them back again in the fall. The general idea is that this allows us all to make better use of natural daylight. However, DST has many detractors—and rightfully so.

When Is Daylight Saving Time This Year? When Does the Time Change?

To remember which way to set their clocks, folks often use the expression, “Spring forward, fall back.” Note that these dates are for locations in the United States and Canada only; other countries may follow different dates.

  • Daylight Saving Time begins on Sunday, March 14, 2021 at 2:00 A.M. On Saturday night, set your clocks forward one hour (i.e., losing one hour) to “spring ahead.”
  • Daylight Saving Time ends on Sunday, November 7, 2021, at 2:00 A.M. On Saturday night, set your clocks back one hour (i.e., gaining one hour) to “fall back.”

Note: Since the time changes at 2:00 A.M., we generally change our clocks before bed on Saturday.

Is it Daylight “Saving” or “Savings” Time?

The correct term is “Daylight Saving Time“ and not “Daylight Savings Time” (with an extra “s”), though many of us are guilty of saying it the wrong way. The technical explanation is that the word “saving” is singular because it acts as part of an adjective rather than a verb.

The History of Daylight Saving Time

Why Did Daylight Saving Time Start? 

Blame Ben? Benjamin Franklin’s “An Economical Project,” written in 1784, is the earliest known proposal to “save” daylight. It was whimsical in tone, advocating laws to compel citizens to rise at the crack of dawn to save the expense of candlelight:

Every morning, as soon as the Sun rises, let all the bells in every church be set ringing: and if that is not sufficient, let cannon be fired in every street to wake the sluggards effectually… . Oblige a man to rise at four in the morning, and it is probable that he will go willingly to bed at eight in the evening.”

DST’s True Founder? 

The first true proponent of Daylight Saving Time was an Englishman named William Willet. A London builder, he conceived the idea while riding his horse early one morning in 1907. He noticed that the shutters of houses were tightly closed even though the Sun had risen. In “The Waste of Daylight,” the manifesto of his personal light-saving campaign, Willet wrote, “Everyone appreciates the long, light evenings. Everyone laments their shrinkage as the days grow shorter; and nearly everyone has given utterance to a regret that the nearly clear, bright light of an early morning during Spring and Summer months is so seldom seen or used… . That so many as 210 hours of daylight are, to all intents and purposes, wasted every year is a defect in our civilization. Let England recognise and remedy it.”

Willet spent a small fortune lobbying businessmen, members of Parliament, and the U.S. Congress to put clocks ahead 20 minutes on each of the four Sundays in April, and reverse the process on consecutive Sundays in September. But his proposal was met mostly with ridicule. One community opposed it on moral grounds, calling the practice the sin of “lying” about true time.

World War I Led to Adoption of DST

Attitudes changed after World War I broke out. The government and citizenry recognized the need to conserve coal used for heating homes. The Germans were the first to officially adopt the light-extending system in 1915, as a fuel-saving measure during World War I. This led to the introduction in 1916 of British Summer Time: From May 21 to October 1, clocks in Britain were put an hour ahead.

The United States followed in 1918, when Congress passed the Standard Time Act, which established the time zones. However, this was amidst great public opposition. A U.S. government Congressional Committee was formed to investigate the benefits of Daylight Saving Time. Many Americans viewed the practice as an absurd attempt to make late sleepers get up early. Others thought that it was unnatural to follow “clock time” instead of “Sun time.” A columnist in the Saturday Evening Post offered this alternative: “Why not ‘save summer’ by having June begin at the end of February?”

WWI-era Daylight Saving Postcard

The matter took on new meaning in April 1917, when President Woodrow Wilson declared war. Suddenly, energy conservation was of paramount importance, and several efforts were launched to enlist public support for changing the clocks. A group called the National Daylight Saving Convention distributed postcards showing Uncle Sam holding a garden hoe and rifle, turning back the hands of a huge pocket watch. Voters were asked to sign and mail to their congressman postcards that declared, “If I have more daylight, I can work longer for my country. We need every hour of light.” Manhattan’s borough president testified to Congress that the extra hour of light would be a boon to home gardening, and therefore increase the Allies’ food supply. Posters chided, “Uncle Sam, your enemies have been up and are at work in the extra hour of daylight—when will YOU wake up?”

With public opinion in its favor, Congress officially declared that all clocks would be moved ahead one hour at 2:00 A.M. on March 31, 1918. (Canada adopted a similar policy later the same year.) Americans were encouraged to turn off their lights and go to bed earlier than they normally did—at around 8:00 P.M.

Farmers Did NOT Favor DST

Many Americans wrongly point to farmers as the driving force behind Daylight Saving Time. In fact, farmers were its strongest opponents and, as a group, stubbornly resisted the change from the beginning.

When the war was over, the farmers and working-class people who had held their tongues began to speak out. They demanded an end to Daylight Saving Time, claiming that it benefited only office workers and the leisure class. The controversy put a spotlight on the growing gap between rural and urban dwellers. As a writer for the Literary Digest put it, “The farmer objects to doing his early chores in the dark merely so that his city brother, who is sound asleep at the time, may enjoy a daylight motor ride at eight in the evening.”

The Daylight Saving Time experiment lasted only until 1920, when the law was repealed due to opposition from dairy farmers (cows don’t pay attention to clocks). No fewer than 28 bills to repeal Daylight Saving Time had been introduced to Congress, and the law was removed from the books. American had tolerated Daylight Saving Time for about seven months.

DST Returns 

The subject did not come up again until after the attack on Pearl Harbor, on December 7, 1941, and the United States was once again at war.

During World War II, Daylight Saving Time was imposed once again (this time year-round) to save fuel. Clocks were set one hour ahead to save energy.

After the war (which concluded with Japan’s final surrender on September 2, 1945), Daylight Saving Time started being used on and off in different states, beginning and ending on days of their choosing.

Local Differences and Inconsistency

Inconsistent adherence to time zones among the states created considerable confusion with interstate bus and train service. To remedy the situation, Congress passed the Uniform Time Act in 1966, establishing consistent use of Daylight Saving Time within the United States: Clocks were to be set ahead one hour on the last Sunday in April and one hour back on the last Sunday in October.

That was the rule, but some state legislatures took exception via a loophole that had been built into the law. Residents of Hawaii and most of Arizona did not change their clocks. Residents of Indiana, which straddles the Eastern and Central time zones, were sharply divided on Daylight Saving Time: Some counties employed it, some did not.

In 1986, the U.S. Congress approved a bill to increase the period of Daylight Saving Time, moving the start to the first Sunday in April. The goal was to conserve oil used for generating electricity—an estimated 300,000 barrels annually. (In 2005, the entire state of Indiana became the 48th state to observe Daylight Saving Time.)

Daylight Saving Time Today

The current daylight saving period was established with the Energy Policy Act of 2005, which went into effect in 2007.

Today, most Americans spring forward (turn clocks ahead and lose an hour) on the second Sunday in March (at 2:00 A.M.) and fall back (turn clocks back and gain an hour) on the first Sunday in November (at 2:00 A.M.). See how your sunrise and sunset times will change with our Sunrise/set Calculator.

However, farmers’ organizations continue to lobby Congress against the practice, preferring early daylight to tend to their fields and a Standard Time sunset for ending their work at a reasonable hour. Some farmers point out that the Daylight Saving Time is deceptively misnamed. “It is a gimmick that changes the relationship between ‘Sun’ time and ‘clock’ time but saves neither time nor daylight,” says Katherine Dutro, spokesperson for the Indiana Farm Bureau.

Most of Canada is on Daylight Saving Time; only portions of Saskatchewan and small pockets of British Columbia remain on Standard Time year-round. However, the practice has its detractors. In the words of a current-day Canadian poultry producer, “The chickens do not adapt to the changed clock until several weeks have gone by, so the first week of April and the last week of October are very frustrating for us.” Similarly, one Canadian researcher likened an increase in traffic accidents to the onset of Daylight Saving Time. Other experts insist that the extra hour of daylight reduces crime. 

As of March 2020, an impressive 32 states have proposed bills to end the practice of switching clocks. However, the legislation can only go into effect if the federal law changes. The Uniform Time Act would need to be amended to allow such a change. See the latest on which states have passed bills to put a stop to DST changes.

Time to END it now. The golf courses have lights at night. The kids can carpool rides in the morning, most of them don't walk anymore, anyway, ///well , not in small towns & rural areas. If parents can drive for basketball games at night, they can adjust their times in the morning. Period.

end this crap and stay on sun time.


It seems that everybody is in favour of getting rid of daylight saving time, according to these comments, too bad the powers that be don’t listen to the majority population and get rid of it


Get rid of it!

Daylight Saving Time

They should just pick one and stick with it instead of the yearly back and forth.

Dailight saving time

Reading through many comments, I have yet to find one that mentions people on a strict medication schedule and how the change upsets this and we suffer for a few days to adjust to it. You cannot save time, let our God intended days and nights stay at EST!


It is way past time to stop this yearly nightmare!! Animals do not recognize this old archaic method, and takes humans weeks to adjust. Time takes care of it self. The days become longer and shorter naturally.


I grew up in a small country that had the same time zone throughout. When I moved here, DST was something strange to me. I don't like it, especially on those very, very dark mornings in winter. Frankly, I don't see any benefit of it at all. If it was meant to save energy, it has failed. We still use energy to heat homes, cool homes and drive to and from work, etc. The law needs to be repealed so we can enjoy the natural order of time and season that God provided for us.


The sun does not change when we work, how late we stay up or when we get up in the morning. During the daylight hours we enjoy the sun and all it gives us. If a company wants to have workers in at a specified time then that is what they do. If you come to work in the dark some of the year so what. We need to stop trying to change and control everything in the world and just adapt to the changes around us. This year lets just go back to Standard and leave it there forever.



daylight savings time

I am with those that wish we stayed standard time without the changes. We lived 8 years in Japan where they don't do the daylight savings time change. It was very nice not to have to adjust my sleeping times or mess with getting up an hour earlier than what my body was accustomed to. I do wish that Missouri would get rid of it the way Arizona has, but I'm sure that won't happen.


I may not get this quote quite right, but I believe it originates from a Native American. 'Only a moron believes that cutting an inch off one end of a blanket and sewing it on the other end gets you a longer blanket.'

There lies our conundrum

As you read through the posts. Some are for DST and others for standard time. We have some states that want to stay on DST and some that do not. We certainly can not have it where every state just does it on thing. Imagine trying to keep up with which state is on DST or not. I suppose this is why no decision has been officially enacted. Looks like it will take the entire country voting in order to enact anything. I can see the ads now.

Daylight Saving Time

I wish they just stay on DST year round I hate the changing back and forth but enjoy the later daylight in the summer.


Obsolete practices that no longer need to exist in the 21st century with the move to renewable energy sources like wind and solar. DST instead has now become mindless pablum for DJs and TV morning show hosts to caw about as they banter back and forth incessantly.


simple get rid of it


If we have to have DST it should be from May 1st to October 1st, this starting earlier and ending later every year needs to end.

Daylight saving time

Do away with it,it’s ridiculous and a pain in the a——.Change your work hours if you don’t like the sun’s hours

DST yea or nay

It's time for us in the US to eliminate DST and go to GMT as our time reference.
GMT would also eliminate the need for time zones. It would of course take an act of Congress to do this, as so very much commerce would have to change also.


Get rid of it! Winter is bad enough without spending more time in the dark.


Isn't DTS stupid? If you need wake up earlier or later, you do not change time on your clock - you just adjust alarm time. Americans.......


Dalight saving time needs to end now. There's no point and it's annoying. End it already!!!


I agree about letting DST die


It only makes Comed richer because it is always dark and you have to pay for using more electricity

Daylight Saving Time

I lived in Southern Indiana for 6 years when it was Eastern Standard Time & clocks were never changed. It was such a pleasure to not do so as these changes do have an effect upon our sleep & other schedules - ie. feeding animals. It made little difference regarding how long the light lasts into early evening. You just adapt - quite easily, I must say. Moving back to the East & once again having to conform to clock changes was annoying at the least & disruptive to sleep & schedule at the worst.

The sun riseth and the sun sets

I think we are past the point of there being any benefit to adjusting the time on the clocks twice a year. Many workers either use the sun as their guide, or are now on "flex" time, so what it says on the clock rarely matters. Repeal the law and make Standard Time the standard again.

Day light saving time cost lives and health

it's debatable that we can still save energy by use of DST given people's lifestyle. Above all every year hospital emergency rate goes up on the day of going DST. people dont get enough sleep or can't adjust the biological clock on demand


It keeps getting pushed further into the winter, I have no desire to be driving in dark 24/7 just stop with the policy, there are many downsides to it summer ends let fall begin and winter into spring, this is no longer serving the greater good

Daylight saving time

we no longer have any need for daylight saving time. Please let's let It die. Let's go back to standard Time in November and then stop changing the clocks.

Daylight saving time

You state we change the clocks on 1 November 2020! All my diarys state 25 October 2020. Which is correct?

DST 2020

The Editors's picture

In the US, Daylight Saving indeed ends on Sunday, November 1, 2020. Elsewhere, that may not be the case. (In the UK, for example, DST ends on October 25, 2020.)
