Italy will adopt again the daylight saving time in 2025, with the official change taking place in the early hours of March 30, a Sunday. As in previous years, clocks will be moved forward one hour at 2 a.m., going directly to 3 a.m.
The measure follows the guidelines of the European Union, which establishes the start of summer time in the last week of March for all member countries.
Purpose of Daylight Saving Time
The main reason for adopting daylight saving time is to save electricity. By delaying dusk by one hour, the consumption of artificial lighting is reduced. Studies by the company Terna, responsible for the Italian electricity grid, show that between 2004 and 2012 the change generated savings of more than 6 billion kilowatt-hours, resulting in a cost reduction of around 900 milhões de euros.
History of summer time in Italy
The first implementation of daylight saving time in Italy took place in 1916, during the First World War, and remained in place until 1920. During the Second World War, the measure was suspended and reintroduced several times, being definitively adopted in 1966.
Possible end of daylight saving time
In recent years, there has been discussion about the possibility of abolishing daylight saving time in Europe. However, Italy chose to maintain the current system, citing a lack of conclusive evidence on the impacts of the change on the population's well-being. Furthermore, discontinuity between countries could affect the EU's internal market and generate logistical difficulties.
Daylight saving time will remain in effect until the last Sunday in October 2025, when clocks will be set back one hour, returning to standard time.
Difference between Brazil and Italy
During the summer time in italy, the time difference between Italy and Brazil varies according to the time adopted in Brazil. See how it is:
- Italy (Summer Time) x Brasilia (Standard Time – no daylight saving time): Italy stays 5 hours ahead Brasilia time.
- Italy (Summer Time) vs Brasilia (with summer time, if applicable): if Brazil adopts daylight saving time (which has not happened in recent years), the difference would be 4h.
In other words, if in Rome... 12:XNUMX (noon), in Brasilia will be 7 am. This difference remains until the last Sunday of October 2025, when Italy returns to standard time and the difference rises to 4 or 5 hours, depending on Brazil.
