Lsummer time 2022 will come into effect at night between Saturday 26 and Sunday 27 March. At two in the morning (or the next morning, more reasonably) we will have to move the hands advance by one hour. For those wondering if this time we "gain or lose an hour of sleep", the answer is simple: we lose it. That's why we do it on Sundays.
1) How long is summer time 2022?
Summer time lasts seven months: on October 23 solar time will come back into effect and we will have to turn the clock back one hour.
2) What is daylight saving time for?
The aim is to optimize the hours of light to reduce consumption. Terna, the company that manages the Italian electricity grid, makes it known in a note that - thanks to summer time 2022 - Italy will save over 190 million euros, reducing consumption by about 420 million kilowatt hours. In environmental terms, the benefit can be quantified in a very significant cut in emissions: we are talking about about 200 tonnes of carbon dioxide less in the atmosphere.
3) When do you save the most with summer time 2022?
"The months with the greatest energy savings are April and October - writes Terna - In fact, moving the hands forward by one hour delays the use of artificial light at a time when work activities are still in full swing . In the summer months, the delay effect in turning on the light bulbs occurs in the evening hours, when work activities are mostly finished, and records less evident values in terms of electricity savings”.
4) How much have we saved so far?
Again according to Terna, between 2004 and 2021 Italy saved around 10,5 billion kWh thanks to summer time, which, in economic terms, corresponds to over 1,8 billion euros.
5) Wasn't the alternation between summer time and winter time supposed to be abolished?
It has been talked about for years in Brussels, even if the idea would be to leave each EU state free to choose whether or not to continue alternating between summer and winter time. However the international dispute is resolved, Italy does not seem inclined to change the time change that has been in force for decades now.
