The basic concept is to take advantage of the extension of the days that anticipate the beginning of the productive life of the country, in spring and summer, the sun rises before 6 am, but typically Italians wake up around 7 am; If you shift the time by an hour, you can still have natural light in the morning and gain a full hour of light for the evening by delaying energy consumption for lighting. From 2004 to 2021, according to the analysis of the company led by Stefano Donnarumma, the decrease in electricity consumption for Italy due to summer time amounted to a total of about 10.5 billion kWh and allowed citizens to save more than 1.8 billion euros. In spring-summer, the months with the greatest energy savings are April and October. In a few days, the solar time will return and the hands will move back an hour. Let`s see when this changes and how it works. Solar time will therefore return in 2021 on the night of Saturday 30 to Sunday 31 October. In addition to the consequences on people`s health, with some side effects associated with jet lag, such as fatigue, irritability, loss of concentration and productivity at work, nausea and loss of appetite, we must also take into account the impact on energy consumption and on the pockets of families related to the time change. In autumn and winter, when the solar season begins, they become more expensive for families and the surrounding area. Speaking of numbers, Terna, the company that manages the national grid, estimated that only “in 2020, the benefits of summer time saved 400 million kWh (for an average annual electricity consumption of about 150,000 families), a figure equivalent to a reduction in CO2 emissions into the atmosphere for 205,000 tons and an economic saving of about 66 million euros”. Sunday, October 23, 2022 ends summer time and gives way to the return of solar time 2022 (winter time in Italy). In fact, moving your hands for an hour delays the use of artificial light at a time when professional activities are still in full swing. During the summer months, the “delay effect” when lighting bulbs is placed in the evening hours, when work activities are largely completed and show less obvious values in terms of electricity saving. From 27.
Daylight saving time will apply again in March 2022. In spring, the hands move forward, in autumn recede. That`s why, with daylight saving time, you sleep an hour less every hour, and with winter, you gain an hour of sleep. To learn more about daylight saving time, browse the gallery. One of the reasons why the abolition of the time change is long talked about is its impact on people`s well-being and habits, which is also supported by scientific studies. While shorter days can cause symptoms of depression, the arrival of daylight saving time with more hours of daylight and less sleep brings temporary decompensation comparable to a small jet lag. The table shows more than 100 years of daylight saving time 1916-2025 with the start and end time extremes and with the length of the validity period in days. From 1921 to 1939 and from 1949 to 1965, daylight saving time was never introduced, while daylight saving time, introduced on 15 June 1940, ended on 2 November 1942 for a total of 870 days after more than two years of validity. We remind you that at the start time of the DST validity period, the clocks and all other timing systems must be advanced by 60 minutes, while at the end of the period, the reverse process must be carried out by moving the hands of the clocks back 60 minutes. The years after 2021 are marked in grey to take into account the possible abolition of summer time in Europe on the proposal of the European Commission. We will go to sleep on Saturday, March 26 with the old time and we will wake up with the new one, in practice on Sunday we will have one hour less to sleep, but usually the time is changed after waking up :-).
March is not only the month when spring arrives, but also the month when we switch from winter time to daylight saving time, with the 2021 time change still under discussion. In fact, there is still talk in Europe about the possibility of abolishing the transition from one system to another, but the latest news from Brussels says that Italy is in favour of maintaining it. Standard time comes into effect this weekend and remains active until the last weekend of March, when daylight saving time returns and we have to move the hands forward one hour. Meanwhile, technology is on our side, in fact, all electronic devices such as PCs, tablets and mobile phones are automatically updated. Summer time was first introduced in Italy on 3 June 1916 and has applied throughout the European Community since 1980. The length of daylight saving time has changed over time: the countdown for the return of winter time is on: on the night of Saturday 30 to Sunday 31 October 2021, the hands will actually be moved back one hour, from 3 to 2. This means that there will be an extra hour of darkness each day, even if there will be more light in the morning, typical of the fall and winter periods, and you will sleep an hour more, at least until Sunday, March 27, 2022, when daylight saving time returns. Even for the most distracted, don`t worry: now technology does everything automatically, smartphones, PCs and tablets will update, and all you have to do is change the wall clocks and traditional wrist clocks. Recall that in Italy, the transition from winter time to summer time has been in force since 1966, after being applied for the first time in 1916, then abolished and confirmed several times until it was promulgated by a special law in 1965. For three years, there has been a debate between the countries of the European Union, where there are three time zones to abolish winter time and maintain summer time every 12 months, but the pandemic has frozen the discussion. Here in Italy, daylight saving time 2021 starts on Sunday, March 28 at 2:00 a.m.
and advances the clock by sixty minutes, then at 3:00 a.m. In Europe, the changeover also applies to all countries in the central zone, while for Eastern and Western Europe, the transition day is always the last Sunday in March, but at 03:00 and 01:00 respectively. Daylight saving time also returns in 2022. On the night of Saturday 26 to Sunday 27 March, the hands of all clocks are advanced from 2 to 3 o`clock. You sleep less, but you gain an hour of light. However, changing times are a topic that has been discussed in Europe for years: some countries want to abolish it, others do not. Here are all the curiosities about this convention, from its history to its impact on health and economic benefits. From the differences between summer time and winter time to their diffusion around the world, suffice it to say that the changeover to summer time between 2004 and 2012 saved more than 6 billion kilowatt hours. Back to solar time, the reverse process will be carried out on Sunday, October 30, 2022 at 03:00 (so in the night from Saturday to Sunday), also in this case, the hands must be returned one hour according to the standard procedure.
