When does Daylight Saving
Time begin in 2022?
Find out the background of daylight saving time and when it was implemented.
On Sunday, March 13, 2022, at 2 a.m. local time, the clocks advanced by an hour to signal the start of daylight saving time. This Sunday, Nov. 6, at 2 a.m. local time, the clocks will advance once more as daylight saving time, which is occasionally referred to incorrectly as daylight savings time, comes to an end for the year. Benjamin Franklin initiated a long tradition of changing the clocks in the fall and spring to preserve energy. The U.S. Senate unanimously approved legislation in 2022 to make daylight savings time permanent, but the house is presently blocking the measure.
In order to avoid missing a crucial meeting or losing out on an extra hour of sleep, here is a list of when daylight saving time begins and ends each year. Additionally, you'll discover some myths and fascinating information regarding the time shift, as well as the history of daylight saving time and its current implementation.

According to the U.S. Naval Observatory, historically, daylight saving time (DST) started in the summer and ended just before winter, though the dates have altered over time as the U.S. government has implemented new laws (USNO).
When will the time change, then? Beginning in 2007, the second Sunday in March will mark the start of Daylight Saving Time (DST), when people will set their clocks ahead by an hour at 2 a.m. local standard time (so at 2 a.m. on that day, the clocks will then read 3 a.m. local daylight time). Then, on the first Sunday in November, clocks are turned back one hour at 2 a.m. local daylight time to mark the end of daylight saving time (so they will then read 1 a.m. local standard time).
On November 7 of 2021, when most Americans turned their clocks back one hour, DST came to an end in the US. The cycle will then start over again. The United States implemented daylight saving time on March 13, 2022, and it will conclude on November 6, 2022.
DAYLIGHT SAVING TIME: WHY DID IT BEGIN?
According to David Prerau, author of "Seize the Daylight: The Curious and Contentious Story of Daylight Saving Time" (Thunder's Mouth Press, 2005), Benjamin Franklin gets the credit (or the blame, depending on how you feel about the time changes) for coming up with the concept of resetting clocks in the summer to save energy. By advancing the clocks, people may utilize the additional evening daylight rather than squandering energy on lighting. Franklin, who was at the time the ambassador to Paris, delighted in his "finding" that the sun emits light as soon as it rises in a satirical letter to the Journal of Paris in 1784.
DST didn't, however, start in earnest until more than a century later. DST was instituted in Germany in May 1916 as a means of fuel conservation during World War I. Shortly after, the rest of Europe joined in. The United States also implemented daylight saving time in 1918.
Even though President Woodrow Wilson intended to preserve daylight saving time after World War I, farmers opposed it because it would mean losing an hour of morning light in a country that was largely rural at the time. (It is untrue that DST was implemented to benefit farmers.) Thus, DST was eliminated until the following conflict made it popular again. President Franklin D. Roosevelt reinstated year-round daylight saving time at the commencement of World War II on February 9, 1942, dubbed it "War Time."
Chaos resulted from the post-war free-for-all arrangement that let American states and localities to decide whether or not to observe DST. The Uniform Time Act was passed by Congress in 1966 in order to control this "Wild West" mayhem. The first Sunday in April would mark the start of daylight saving time, which would terminate on the last Sunday in October, under this federal rule. However, states were not required to observe DST; they might choose not to.
The Energy Policy Act of 2005 then took effect in 2007, extending the duration of daylight saving time to its current timetable.
WHAT IS THE PURPOSE OF DARK SAVING TIME?
According to timeanddate.com, less than 40% of the world's nations observe daylight saving time. Those who do observe DST, however, benefit from the natural light throughout the summer evenings. This is due to the fact that when Earth transitions from the winter to the spring and summer seasons, with the summer solstice marking the longest day of the year, the days begin to grow longer. Earth, which circles around its axis at an angle, is inclined straight toward the sun during the summer season in each hemisphere.
Due to a more pronounced seasonal variation in sunlight, regions closest to the poles and furthest from the equator benefit the most from the DST clock change.
As fewer vehicles are on the road when it's dark outside, research has shown that there are fewer traffic accidents when there is more daylight in the evenings. For full-time employees, extra daylight may also mean more outdoor exercise—or any activity at all.
Energy savings has long been the stated justification for daylight saving time. As part of the war effort, the time change was first implemented in the U.S. during World War I and then again during World War II. Congress even established a trial period of year-round daylight saving time during the Arab oil embargo, when Arab members of the Organization of Petroleum Exporting Countries (OPEC) ceased exporting petroleum to the United States, in an effort to conserve energy.
But there is little data to support any considerable energy savings. According to Stanton Hadley, a senior researcher at Oak Ridge National Laboratory who contributed to the creation of a report to Congress on extended daylight saving time, brighter evenings may result in reduced use of electricity for lighting. Hadley noted that because lights are now more energy-efficient than they once were, lighting now accounts for a smaller portion of overall energy use. Heating and cooling are likely more important, and some locations might require air conditioning during the longer, warmer summer evenings brought on by daylight saving time.
In a report to Congress that was released on September 30, 2020, Hadley and his colleagues found that the four weeks of additional daylight saving time that were implemented in the United States in 2007 did result in some energy savings, saving about 0.5 percent of what would have otherwise been used on each of those days (opens in new tab). Hadley pointed out that the entire month-long period of daylight saving time may in fact have the opposite impact.
Residential energy use increased somewhat in Indiana between 1998 and 2001, when certain counties adopted daylight saving time. A 2007 analysis discovered that brief adjustments to Australia's daylight saving time for the summer Olympics in 2000 likewise failed to save any energy.
Because there have been so few changes to the policy, it is difficult to compare before and after data, according to Hadley, who spoke with Live Science. This is part of the difficulty in measuring the impact of daylight saving time on energy use. Only a few weeks of time separated the before and after of the 2007 daylight saving time extension. The effects were only observed in Indiana and Australia.
Hadley concluded that the real reason the United States continues to observe daylight saving time is probably not related to the energy issue.
Energy savings "are not the primary driver in the grand scheme of things," he claimed. People are trying to make the most of the daylight hours in the evening.
