In 1996, through the Law 4 June 2010 n.96, art.22 established that all EU countries have common dates for the beginning and the end of summer time. However, in 1966 it was decided to stabilise this practice and, during the 1980s, daylight saving time was extended from 4 to 6 months (March to September). Subsequently, daylight saving and standard time alternated during the Second World War, with an interruption in 1948. Initially, this time remained in force until 1920. In Italy, daylight saving time was introduced at midnight on 4 June 1916, by legislative decree 631 of. And in Italy? Italy and the countries involved in the conflict adopted reflexively and for obvious logistical reasons. The reason lies in the economic needs dictated by the First World War to save energy to support the war effort. His intuition, which fell on deaf ears at the time, was cunningly dusted off by the British manufacturer William Willett, and in 1916 British Summer Time, moving the hands forward one hour in summer, was finally approved. Even though it is not a time zone, daylight saving time is one more aspect to consider when travelling abroad or interacting with other countries.Īccording to history, it would seem that back in 1895 it was New Zealand entomologist George Vernon Hudson who proposed moving the hands (by a good two hours, however) to enjoy the daylight hours in summer. Basically, the purpose of daylight saving time would be to take full advantage of the hours of daylight, thus saving energy. On the other hand, daylight saving time involves moving the hands of the clock forward one hour. Solar time is nothing more than the time in our time zone, the natural time of the sun. So, let's summarise: travelling eastwards, the time zone has a positive sign (+), and we add hours while travelling westwards, it has a negative sign (-), so we subtract them.Īt this point, we can introduce the two concepts of solar time (standard time) and daylight saving time (summer time). In the southern hemisphere, Sydney is +10 hours behind Italy. Rio de Janeiro is -4 hours behind Italy and, moving eastwards, Beijing is +7 and Tokyo +8. Moscow is 2 hours ahead, while New York is -6 hours and Chicago is -7 hours behind us. The Canary Islands, however, are 1 hour behind Italy. Paris, Berlin, Madrid have the same time as Rome, so travellers from these cities do not suffer any difference. London is one hour behind Italy, so if it's 12 noon in England, it's 1 p.m. Let's now take a look at some time zones for those travelling in Italy from the rest of the world, but always paying attention to daylight saving time, which we will discuss later. GMT, on the other hand, is the time measured by astronomical observations.Īs of 1 January 1972, the time zone is measured in UTC. It represents the time measured with atomic clocks. UTC ( Universal Time Coordinated) is the Universal Time Coordinated that passes through the Greenwich Observatory. Let's take a brief look at the difference. However, the time zone is measured in UTC, which coincides with GMT except for infinitesimal approximations. The country still uses this local time as standard time today.Italy, compared to GMT ( Greenwich Mean Time), is at GMT+1. In 1893, Italy advanced its clocks by 10 minutes and 4 seconds, so the local time was exactly 1 hour ahead of GMT. It was 49 minutes and 56 seconds ahead of GMT, then the world's time standard. Until then, the country had been using solar mean time, based on Italy's longitude. In Italy, standard time was introduced in 1893. It will become active again after the next clock change as Daylight Saving Time begins or ends. The above time zone is used during other parts of the year. Time Zone Not Currently Being Observed in Italy Offset Central European Time (CET) is used as standard time, while Central European Summer Time (CEST) is observed when Daylight Saving Time (DST) is in force.
