Daylight Saving Time. Why do we change the clocks?
The tradition of moving clocks forward during the summer months is known around the globe as Daylight Saving Time (DST). With the arrival of spring, people set the clocks one hour forward from the standard time. Although this practice is peculiar to the majority of the western countries, not all regions and states accept DST.
How does DST work?
Around the globe, people set clocks one hour forward on the last Sunday of March. Nevertheless, in the United States, DST starts on the second Sunday of March. Also, the time when the shift occurs differs from country to country. Some regions forward the clocks in the middle of the night at 01:00 am or 02:00 am local time. This practice signifies the arrival of the spring and lasts till the Autumn. Meanwhile, the return to the standard time takes place in October or November.
Keep in mind the process of changing time and recall it easily!
DST around the world
Countries on Standard Time Zone only
Considering that DST is the widely applicable practice in the world, some countries developed their own rules and terminology for this occurrence. In particular, the countries which do not follow DST live in the Winter Time Zones (Standard Time Zone). Among the most popular countries which do not observe DST are the following:
Countries on DST only
Countries on standard time and DST
And, as we know, a lot of countries use Standard Time Zone alternating it with DST during certain periods of the year. In the table below are shown the dates of the beginning and the end of Daylight Saving Time in the majority of these countries:

Time change process in different parts of the world
The time change process affects in a different way distinct parts of society. For example, industrialized communities don’t experience that much of a difference since they follow the same schedule throughout the year. For people who have a regular job or have to attend educational institutions like kindergartens, schools, universities, etc, their timetable stays the same during the whole year. Contrariwise, an agrarian society totally depends on solar time and it is mostly conducted by the actual duration of the daylight. In this case, it will change seasonally and will vary according to the part of the world. In some places, like tropics in the North and South, in summer daylight will remain longer than in winter, because of the specifics of the Earth rotation and position towards the sun.
For the majority of the population who keep the same routine throughout the year, resetting clocks means that they will have more time for other activities after they are finished with the work or studying since they had to start their day sooner by waking up one hour earlier. It sounds good and many people find this practice to be reasonable. Nonetheless, it also supposes to begin the day in the darkness during the winter because of having one less hour in the morning which makes this measure questionable for some people.
Although the change of the times of sunrise and sunset is relatively even during the seasons’ change, Daylight Saving Time supporters claim that this way they have more time after their daily work routine and they would rather wake up earlier to take advantage of the longer daylight afterward. They also claim this measure helps to reduce energy use because of longer days, so the need for lighting and heating is lower as well. But the actual results show that this statement is not totally correct.

Useful tips for drivers
To make the transition from wintertime to summertime easier and safer and avoid possible accident, we suggest going to bed earlier and waking up at the same time, working out, and finally — don’t staring at smartphone screen in the evening!
Spelling
Common synonyms and the correct way to spell DST
DST abbreviation stands for Daylight Saving Time and it is used to define the practice when we advance our clocks one hour ahead. The other variation is Daylight Savings Time with the “s.” This way of spelling DST isn’t completely correct but considering its wide and quite frequent use around the world, it became acceptable.
How many people in the world spell DST incorrectly and why?
Although the correct way of spelling DST is Daylight Saving Time, the majority of people around the world would use Savings. We are talking about a large part of people from Canada, the USA, Australia, India and some European countries, including the UK and France.
The correct way of spelling this term is more common in some Asian countries such as Vietnam, Japan, and Philippines and amongst European countries like Germany, Italy and Netherlands.
The correct way of spelling DST is Daylight Saving Time because the point is the saving of daylight, that’s why it seems correct for it to be Daylight Saving Time, not Daylight Savings Time. (We are not talking about multiple savings.) The singular is the original form and seems to be the standard. However, it’s common for the plural form to be used. Savings is often used when the fact of the time change is mentioned by the media or in casual conversation. And sometimes Savings is even seen on calendars.
Current influence of DST around the world
The most inconvenient time zones
In nowadays reality, it would be very complicated to rearrange our lives around a day length that is continually changing every day. Instead of that, the clocks and watches show us a mean time that is based on the length of the actual solar day averaged throughout the whole year. This is commonly referred to as the mean solar day and its length is 24 hours. There are two reasons for the actual solar day to differ in length from day to day: first of all, the orbit of the Earth around the Sun is an ellipse and not a perfect circle.
As a result, some parts of the world don’t have an even length of day and night when at some places the sunrise and sunset times hardly vary. For example, it is a case of Kenya which is situated right on the equator. This country never implemented a DST but the solution was shifting from one time zone to another.
DST history around the world
First implementations on the national level
During the First World War, in 1916, Kaiser Wilhelm was the first leader who decided to enable DST because he recognized that increasing the hours of daylight nationwide would benefit the energy consumption and health of people and soldiers in particular.
After Germany, many other European adopted the Daylight Saving Time due to its perceived benefits for the population and energy efficiency.
The United States joined the format of DST
Along with the adoption of the Standard Time Act of March 19, 1919, in the United States, the first time DST was implemented was at 02:00 am on March 31 in the same year. On this day, people were asked to stop their clocks for one hour. The return to the standard time was scheduled in seven months.
However, following the World War, this practice was criticized by the population and politicians of the United States. Although DST became optional for the areas, the major part of the country proceeded to use it till today. Only several areas decided to opt-out from DST because it was not suitable due to the climate conditions.
The benefits of Daylight Saving Time
A craving to encourage energy saving and reduce electric lighting was, and still remain, as an initial reason for implementing such a thing as Daylight Saving Time. Some of the estimates suggest that this measure can help to reduce energy use around the country for at least 0.5%. A lot of studies were conducted to prove these results and some of them were based on different systems of measuring data and complex simulations. At the same time, there are just as many studies that show the opposite effect of implementing DST and claim that there is no noticeable benefit from this practice or even argue that the results are actually worse if the fuel consumption is taken into account. Although, it is proven that it definitely helps to reduce energy and heating usage in the evening, but it most likely results in higher demand for gasoline and electricity during the dark and cold mornings.
DST in Europe
With the historical adoption of DST in Germany, other countries recognized the positive effects of this practice. In particular, it was evident that people would benefit from the extra hour of daylight while using less energy. As a result, the majority of the European countries adopted DST as the annual tradition.
Regulations
Subsequently, these legislative bodies constantly study the effectiveness of this practice and how it benefits the citizens. Also, the organizations collect the data from the studies and public opinion to determine whether any amendments to DST are needed.
Public opinion on DST
Since the adoption of DST, many people have expressed their concerns regarding the implications of sudden changes in the biorhythm. Since citizens and members of parliament reconsidered their attitudes towards DST and asked to make changes, multiple public hearings were organized.
The most important hearing was organized in 2015 with a discussion on how to rework summertime or cancel it altogether. Moreover, the citizens criticize DST and appeal to the EU summertime agreements. As a result, the European Parliament often receives public petitions on this subject with the proposition to change the procedures of DST.
DST in the United States
The population and scientists express criticism concerning the effectiveness of DST in the United States. In particular, the primary argument remains to be the fact that the benefits of increasing daylight were relevant only during times of low technological development. Energy conservation is no longer effective with the increase of daylight hours.
Criticism
The shifts of the clocks affect the dairy farmers because it is difficult for cows to change the biorhythm. As a result, this issue negatively contributes to their ability to produce milk. Subsequently, DST is considered to have a negative impact not only on the human sleep cycle but also on the productivity of agriculture.
Which states do not observe DST
Although the United States accepted the use of DST for the country, there are several exceptions. Namely, Hawaii decided not to implement DST due to the notion that during the year, the daily sunlight cycle is the same. Similarly, the U.S territories like the Virgin Islands, Puerto Rico, Guam, and American Samoa also do not require DST due to the same reasons. In this regard, one may admit that the areas which are located near the equator do not benefit from the extra hour of daylight.
Nevertheless, the state of Arizona has unique attitudes towards DST. The state decided not to follow the tradition of daylight saving and yet the Navajo Reservation which is located on the territory of the state does set clocks one hour forward. Considering the climate and extremely hot temperature during the summer months, the additional hour of daylight is more damaging than effective for the population of Arizona. Therefore, the residents of the state actually would appreciate even fewer daylight hours during
Evolution of the DST remain the same through the time
Countries that abandon DST and their reasons
From the beginning, the main reason for introducing Daylight Saving time was to save energy consumption, but in reality, it doesn’t make that much of a difference since saved energy in the evening results in higher use of electricity during the dark mornings and increases fuel usage.
This issue was mentioned by Marita Ulvskog, a member of the European Parliament from Sweden who wrote the transport and tourism committee’s draft resolution on discontinuing seasonal time changes.
Countries that consider abandoning DST
Some of the countries that observe DST are still considering whether they should end this practice or not.
Consequences of the end of the Daylight Savings system
Furthermore, with the uninterrupted summertime implemented, the rate of traffic accidents most likely would drop down since people would return to their homes after exhausting work during the daylight.
In the case of Spain, besides removing the need to reset their clocks, this would permit the country to adopt the most relevant geographical time zone, which would be the Greenwich meridian.
On the other hand, specifically in the case of Spain, some parts would be affected if this measure was implemented. For example, in some autonomous communities like Galicia, the light wouldn’t reach them until 9:30 am. It causes some complications for the human body since it is more natural for us to do daily activities when there is a light outside.
It should also be noted that our resting time is affected when it gets dark later. It is amazing to be able to enjoy more hours of sunlight, but it also means that the time of going to bed will be postponed. As a result, we will be more tired when we will have to wake up for school or work, as the time for getting up will remain the same. All of this can lead to a recession in our productivity and make our performance worse.
The reasons for some countries to reintroduce DST back
In the early 1930s, Mexico implemented Daylight Saving Time but it lasted only for a season. Later, in 1939 it was brought back due to a power shortage in a period of severe drought and lack of water for hydroelectric plants. This continued for much of the next 20 years and probably was the main reason for DST from 9 December 1940, about two months into the dry season, until 1 April 1941.
Another Interesting case is Tunisia which first had daylight saving on 15 April 1939, and start and end dates in the war years were the same as France since that area was a French protectorate. The other exception was for eight days in 1943 when Tunisia reverted to Standard Time. The reason wasn’t Ramadan as it was in September. A likely explanation was that the Allies wanted earlier dawn times during a period of heavy fighting with German and Italian troops. After that, the government would implement it for some years because of Ramadan, the energy consumption didn’t seem to show much of a difference.
Regulatory institutions
Organizations steering time policy and standards around the world
The system of worldwide time zones was developed by Sanford Fleming back in 1878 but it is still used nowadays. His idea consisted in dividing the world into 24 time zones, giving each part 15º space. The concept came from the fact that the Earth is round and its rotation lasts approximately 24 hours. So this way, the whole surface of the planet would be divided into 24 “slices” each, or 15º because it is what we get if we divide 360 by 24.
DST in popular culture
Like anything that has an undeniable impact on our lives, Daylight Saving Time forms an important part of people’s routine around the world. As a result, it is mentioned more and more often in the entertainment industry as well.
People share on the Internet the issues they have experienced because of the DST and funny stories that have happened to them, posting on their social media and creating memes.
And not only this but our favorite TV shows would reflect the reality we are facing at the moment, and make us laugh at it. For example, in the TV show Veep, in one of the episodes, Jonah’s (the main character) inability to understand Daylight Saving Time causes him problems at work but ultimately gives him a bill to champion. The episode contained a lot of funny moments related to the issues caused by DST.
However, there is a rumor that candy companies lobbied for a long time to push back the end of daylight saving time, allegedly even putting little candy-filled pumpkins on every senator’s chair back in 1986. But it is just a rumor and its legitimacy has been debated, but it’s fun to think about.
