Summer time October 2021: tonight the time change. When and how to move the hands

by admin

Milan, 30 October 2021 – Thewinter time. Soon we will say goodbye todaylight saving time: the change it will happen in the night between Saturday 30 and Sunday 31 October, at 3.00. So technically tomorrow, but basically on the night of today.

How to move hands?

When 3 o’clock strikes, the hands will move back one hour, bringing us back to 2 am and giving us an extra hour of sleep. As usual, solar time will mark the cold months, up to March 2022 when, in the night between Saturday 26 March and Sunday 27, daylight saving time will be reset again. Most electronic devices are designed to adjust automatically: the analog home clock, on the other hand, cannot ignore our intervention. If it is true that the days will be shorter and that the darkness will “eat” a good part of the afternoons, in the morning we will have 60 more minutes of light. According to data from Terna, the company that manages the national transmission grid, in the 7 months of summer time the Italian electricity system benefited from lower consumption for 450 million kWh, equal to the value of the average annual requirement of approximately 170 thousand families, with a consequent economic saving of approximately 105 million euros. Positive repercussions also in terms of environmental sustainability: the lower electricity consumption, in fact, has allowed the country to avoid CO2 emissions into the atmosphere for about 215 thousand tons.

It’s the last time?

In recent years, on several occasions, there has been discussions on the advisability of giving up summer time; complete with an official proposal of abolition, advanced between July and August 2018 and supported above all by Northern European countries, led by Poland and Finland. In Scandinavian countries, in fact, where the days are longer, there is no significant gain of light by applying this stratagem; on the contrary, in southern European states, daylight saving time actually lengthens the days with real benefits. In 2019 the European Parliament voted by a large majority in favor of ending the time change from 2021; the pandemic, however, froze all action. We also think about another problem: if individual countries are given the right to choose, in Europe there will be different times in addition to the time zones that already exist. The current presidency of the EU Council, held by Slovenia, has not taken a position but has not even included the discussion in the work program among the proposals on the agenda. In Italy, daylight saving time was adopted and abolished several times until 1965, when it was definitively introduced for a duration of only four months, in 1996 it became seven months, aligning itself with the rest of Europe. In November 2019 the government Count bis he had sent the decision to keep the dual hours in Brussels; the pandemic has subsequently mixed up the cards (and priorities). It is expected to understand if the current Executive intends to take a position on the issue, which in fact remains pending.

History

But who came up with the idea of ​​introducing solar time? There are those who totally download the paternity of the company on Benjamin Franklin even if in reality the scientist and politician – with a lot of humor – in 1784 while he was in Paris as an ambassador, he only wrote a letter to the newspaper Journal de Paris, in which, ironically about the alleged early morning habits of French citizens, he calculated how many candles could have been saved if Parisians had used all the sunlight available during the day instead of getting up late. A satirical goad, in short. Much more serious, in 1895, the proposal of the New Zealand entomologist George Vernon Hudson who asked to advance the clocks by two hours to take advantage of solar radiation during the summer. An intuition that was later taken up by the British manufacturer William Willett, this time finding the support of the House of Commons of the United Kingdom, which in 1916 approved the British Summer Time, that is, the shift forward of the time during the summer, which soon spread to other states as well.
