The arrival of daylight saving time in March requires moving hands forward and, as we have seen in theory, we can sleep an hour less. This change can have an impact on the human body as it can alter the alternation of wakefulness and sleep and circadian rhythms. It is very close to the arrival of solar time in Italy. The transition from daylight saving time to standard time is scheduled for the end of October and consists of moving your hands back an hour. Here is the date of change from summer time to standard time in Italy. Terna, the company responsible for managing electricity flows in Italy`s high-voltage grid, estimates the savings made possible by the introduction of summer time every year. The following table presents these data for several years. The international definition of daylight saving time refers to the time zone and is defined as 60 minutes earlier than UTC (Coordinated Universal Time) in the period established by law. The Italian time zone is UTC+1 and if we add daylight saving time we have UTC+2. In general, tropical countries do not adopt daylight saving time because the variation in daylight hours throughout the year is minimal and does not allow enough hours of daylight in the morning to justify moving your hands back an hour to add light in the evening. The discussion about the possible abolition of daylight saving time began in Europe in 2018, but many countries, including Italy, do not want to give up economic and temporal gains.
In order to promote discussion, northern countries such as Finland, Lithuania, Sweden and Estonia should not be able to enjoy the greatest number of hours of sunshine due to their proximity to the pole. With the end of summer and the arrival of autumn, warm and sunny days give way to rain and cold. In connection with this scenario also comes the time change, which goes from legal to solar. The transition from daylight saving time to standard time has also been confirmed in Italy this year. The change will take place on the night of Saturday 29 to Sunday 30 October 2022, when we can say goodbye to daylight saving time by welcoming solar time. What? Imagine, for example, a person who sleeps every day from 11 p.m. to 7 a.m.: in the summer, the sun rises well before 7 a.m., and therefore, using daylight saving time, it is possible to use the light hour from 6 to 7 a.m. and delay the lighting of electric light by one hour in the evening. In Turin in 1920, the introduction of summer time was also the occasion for contrasts in the workplace, which led to strikes. Solar time remains in effect until the last weekend of March, we return to daylight saving time between Saturday 25 and Sunday 26 March In the past, the days of time change were defined from time to time, while today, in application of a European directive, the process has been simplified by classically defining the entry of summer time on the last Sunday of March and the return to solar time on the last Sunday of October.
“This economy of artificial light is the most immediate and material goal of the advance of daylight saving time; It saves fuels for the production of gas or thermoelectric energy in cities or oil and candles in villages and small population centers, where these lighting methods are most often used. And if we consider that with the currently very high price of fossil fuels, from 400 to 600 lire per tonne – and sometimes even 925 lire, as happened recently in Genoa for a New Pelton wagon – we understand how useful it is to save an hour of gas or electricity production. In fact, think that lignite, despite the commendable efforts of Mr. De Vito, Commissioner-General for National Fuels, is still rare and poorly selected and therefore of an unprofitable yield, and that in Puglia and Sicily many electrothermal power plants are powered with poorly produced gas, with almond peel, with depleted olive pits or with citrus peels from which citric acid and essential oils have been extracted, It is understandable that any measure tends to shorten the life of these plants has a significant impact on the national economy. [4] The summer time introduced by this law, first applied in 1966, lasted four months, from the last Sunday in May to the last Sunday in September. this year, it remained in effect from May 22 to September 24. This period was extended to six months in 1980 by bringing forward the beginning of the first Sunday in April, then from 1981 to the last Sunday in March. Another one-month extension was introduced in 1996, along with the rest of Europe, when the end was postponed to the last Sunday in October. The table shows more than 100 years of summer time 1916-2025 with the temporal extremes of beginning and end and with the duration of the validity period, expressed in number of days.
From 1921 to 1939 and from 1949 to 1965, summer time was never introduced, while summer time introduced on June 15, 1940, after more than two years of validity, ended on November 2, 1942 for a total of 870 days. We remind you that at the time of the start time of daylight saving time, clocks and all other timing systems must be advanced by 60 minutes, while at the end of the period, reversing must be performed by bringing back the hands of the clocks by 60 minutes. Years after 2021 are marked in grey to take into account the possible abolition of summer time in Europe on a proposal from the European Commission. Daylight saving time will also return in 2022: on the night of Saturday, March 26 to Sunday, March 27, the clock hands must be brought forward by one hour. However, this practice has been discussed for years in many European countries that want to abolish daylight saving time in order to introduce a uniform system. Finally, we would like to remind you that for some time there has been talk of a possible abolition of summer time. The reason? Since 2018, many European Union countries have called for the abolition of daylight saving time for a range of economic and temporal benefits. For the time being, however, no clear decision has been made regarding daylight saving time. According to our government, the coming into force of daylight saving time would save us nearly six months a year on electricity consumption.
Details that are very relevant to the lives of many Italians, especially in this period when raw materials have high costs. The main promoter of daylight saving time in Italy was the engineer Luigi Luiggi, who published several articles for introduction and subsequent maintenance. He highlighted the positive aspects of the new time arrangement, in particular a possible saving of 100 to 150 million lire for coal for lighting. [2] [3] From 1980 onwards, the start of summer time was brought forward for a Europe Agreement involving several countries of the European Economic Community. [24] The purpose of daylight saving time is to save energy by using less electric lighting. Daylight saving time obviously cannot increase the available daylight hours, but only induce greater use of the hours of light that are usually “wasted” due to weather patterns.
