READ ALSO: Spring equinox 2022: What it is, when it falls and why it is not always March 21 Let`s take the example of Italy: if with solar time (that is, the one following the natural sunrise), the sun would rise at 4:30 a.m. during the summer months and set at 8 p.m., with daylight saving time (i.e. advance the hands of the clock), is the period of light between sunrise and sunset from 5:30 a.m. to 9 p.m. It is easy to understand that an hour of light between 4:30 a.m. and 5:30 a.m. is less useful than an hour of light between 8 p.m. and 9 p.m. This shift allows, for example, to turn on the lights an hour later in the evening and thus save electricity. The time change has its advantages and disadvantages. Daylight saving does indeed require significant energy saving, as you can make the most of daylight hours during the summer months. It is no coincidence that between 2004 and 2012, an hourly movement of the hands saved about 6 billion kilowatt hours.
When do hands move? By the end of October, we are preparing to welcome daylight saving time with the introduction of winter time. What is going on? Quite simply, we will sleep an hour more, but we will have to give up an hour of light because the days are getting even shorter. In Europe, most countries will again bring forward the date of March 27 this year. In the United States and Canada, daylight saving time came into effect on March 13, while in Russia it has been abolished for years. In Australia, there is daylight saving time: it starts at 2 a.m. on the first Sunday in October and ends at 3 a.m. on the first Sunday in April. The transition to daylight saving time, which will take place on the night of March 30 to 31, can be a real stressor for our body. But there are also undeniable benefits, not only for our well-being, but also for our home, as noted by the experts at Habitissimo.
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. Daylight saving time will apply again from 27 March 2022. The DST story is really funny when you think that it begins with a demonstration by Benjamin Franklin, who wanted people to be earlier risers, saving on the cost of candles, and not just wanting cannon shots fired to wake residents. Daylight saving time also returns in 2022. On the night of Saturday 26. On Sunday, March 27, the hands of all clocks will be 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 spread around the world Looking at the decrease in energy consumption caused by summer time, Italy saved a total of about 10.5 billion kilowatt hours between 2004 and 2021: in economic terms, we are talking about savings for citizens of more than 1.8 billion euros. In addition, a non-secondary factor, the reduction in energy consumption, also corresponds to a lower environmental impact in terms of CO2: summer time should therefore also lead to a reduction in carbon dioxide emissions into the atmosphere of around 200,000 tonnes. When does the time change? Summer time is indeed always applied and only in summer when the sun goes down later and offers the possibility to turn on the light in the house late in the evening. For the State, the transition to summer time is a source of great savings, but the citizen saves not only electricity, but not only. Thanks to the extra hours of light, you can practice activities that you usually do not allow yourself in winter, because it gets dark very early. 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. With summer time, the sun rises later, but the light in the evening lasts longer, from autumn it reverses: more light in the morning, but in the evening the sun sets earlier. Daylight saving time is an international convention adopted to make the most of summer daylight hours and reduce energy consumption.
In 2022, on the night of Saturday, March 26 to Sunday, March 27, we will switch to daylight saving time, which will remain in effect until Sunday, October 30, 2022, when solar time will return and the hands will be moved back one hour. Standard Time 2021: It`s time to say goodbye to daylight saving time! With autumn and winter just around the corner, it`s time for a time change. The hands of the clock are moved back an hour. What does that mean? What will change for all of us? Let`s find out together. Daylight saving time comes after the spring equinox: it begins on the last Sunday in March and ends on the last Sunday in October, when we return to solar time. Sunday, October 23, 2022 ends summer time and gives way to the return of solar time 2022 (winter time in Italy). The issue of abolishing the time change has been discussed for a long time within the EU: a first request to abolish the time change had already been submitted by Northern European countries in July 2018. If countries like Norway, Finland and all the countries of Northern Europe can boast very long days in summer, even the single weather can offer many hours of sunshine, for other nations like ours or Spain, the movement of the hands allows on the contrary a significant energy saving. The discussion within the European Commission led to the formulation of several hypotheses, including the division of the countries of the continent into blocks providing only once for the whole year, with summer time in the countries of the South and winter time in the countries of the North. To date, however, no decision has been made. Daylight saving time in Italy follows European Union rules, although DLL No.
631 was first approved on May 25, 1916. However, daylight saving time was introduced by Law 503 of 1965 without ever stopping. Italian law provided for summer time from May to the end of September. Today, however, daylight saving time starts two months earlier, in accordance with the rules imposed by the European Union. What are the consequences? In terms of personal habits, the most obvious consequence is that it gets dark an hour earlier. But if you lose an hour of sunshine in the afternoon, it is also true that those who are used to setting the alarm early can enjoy an extra hour of light. However, for the return to daylight saving time, it will be necessary to wait until spring and, to be precise, March 27, 2022: on this occasion, the hands will have to be moved again, but forward. Standard Time 2021, when do you change? Tonight. Between Saturday, October 30, 2021 and Sunday, October 31, returns one hour until 3am. A change that allows us to sleep 60 minutes more on weekends, but usually we lose an hour of light.
