On the last weekend of October, daylight saving time returns: hands will have to be turned back one hour, from 3 to 2 a.m. on the night of Saturday 28 to Sunday 29. The good news is that you get an extra hour of sleep. The bad news, however, is that it will get dark earlier in the evening: with the time change, there will be more light in the morning but the sun will set earlier.
Why does the time change? We switch to daylight saving time in the spring to optimize the use of sunlight and consume less electricity. By moving the hands forward we all wake up an hour earlier and in this way we make more use of natural light in the morning and gain an hour of daylight for the evening by turning on the lights later. When the days get shorter, in late fall, we return to daylight saving time instead.
In 1916 a law introduced daylight saving time in Italy for the first time, and over the past century its duration was repeatedly changed until it was set at 7 months in 1996. In the past, different days were set each year for the time change, but today the process is simpler and the dates are always the same: we switch to daylight saving time on the night of the last Sunday in March and return to standard time on the last Sunday in October.
