And, most importantly, it not only saves energy, but also protects the environment, because summer time avoids the release into the Italian atmosphere, during its duration of at least 300,000 tons of carbon dioxide. In general, tropical countries do not adopt daylight saving time because daylight time fluctuations throughout the year are minimal and do not allow enough hours of light in the morning to advance an hour to add light to the evening. The country introduces daylight saving time from the second Sunday in October to the second Sunday in March, but the adoption time can change often. In 2008, for example, daylight saving time ended at midnight on March 30. In 2010, the summer adoption period ended due to the April 3 earthquake,[25] while in 2011, the summer adoption period was extended first to April 2[26] and then to May 7[27] in order to avoid energy crises due to the dry summer. One of the main reasons for deciding to adopt such a change in calendar is the choice of savings. The company Terna, operator of the national electricity grid, announced that in 2016, for example, thanks to summer time in Italy, 573 million kilowatt hours were saved (the kilowatt hour is the measure of electricity consumed). A figure that corresponds to the average annual electricity consumption of 210 thousand households. These schedules were chosen because they are the ones where train and other public transport traffic is kept to a minimum, thus minimizing misalignments from the scheduled daily schedules. Note that summer time starts at the same time throughout the Union: if the change between 2 and 3 takes place in Central Europe, it takes place between one and 2 in Great Britain and Portugal, and between 3 and 4 in Greece. New Zealand, Australia, Samoa and Fiji are the only states on the continent where daylight saving time is introduced. Since they are located in the southern hemisphere, they adopt daylight saving time in spring and southern summer.
The first introduction of daylight saving time in the country took place during World War II; Interrupted after the conflict, it was reapplied in 1957. Daylight saving time was generally applied between the last Thursday in April and the last Thursday in September, changing to the UTC+3 time zone. The time change occurred at midnight (local time) and changed from 23:59 to 1:00 at the beginning of daylight saving time and from 23:59 to 23:00 at the end of daylight saving time. The last country in Europe to introduce summer time in 1981 was Switzerland, due to opposition from local farmers, who also campaigned for the abolition of referendums on the issue. Since 1996, the EU regulation has been used for the beginning and end of summer time. The debate on abolishing the time change in Europe has been going on for three years. The proposal was initially presented between July and August 2018, which was much desired by northern European countries, with the launch of a survey asking EU citizens whether or not they wanted to keep summer time. More than 4.6 million people answered this question: 84% asked that the time change be abolished, keeping only natural time and therefore solar time. The reason for this request was that if in countries such as Spain or Italy, summer time actually extends the days, in the north, where the days are already longer, this effect does not bring any advantage. However, in the ensuing discussion with the European Commission, no clear decision was taken that would satisfy all Member States, so much so that it was even thought that it would go in the direction of abolishing or not en bloc with the southern countries of the EU, which could have kept summer time all year round. The countries of the North, which could have had winter time for 12 months. But a definitive answer has not yet come.
However, in April 2019, President Jair Bolsonaro decided to abolish daylight saving time nationwide, as the energy savings were not significant. The country adopts daylight saving time from the last Friday before April 2 at 2:00 a.m. on Sunday between Rosh Hashanah and Yom Kippur. Until 2005, there were no fixed dates: they were set by the Ministry of the Interior, with the limit of at least 150 days per summer year. [36] Take, for example, a person who sleeps from 11 p.m. to 7 a.m. every day: in summer, the sun rises well before 7 a.m. and, therefore, with daylight time, it is possible to use light time from 6 a.m. to 7 a.m. and delay the switching on of the electric light by one hour in the evening.
The country, which is in the UTC+2 zone, adopts daylight saving time from the last Friday of March to the last October. Most of British Columbia is in the Pacific Time Zone and uses daylight saving time, with the following exceptions: Some European Union countries, such as Iceland, Armenia and Georgia, have decided not to join daylight saving time. The country had previously introduced daylight saving time (transition to UTC+3) from 30 March to 21 September (until 2006, it ended on 30 September). Daylight saving time is now applied from the last Friday in March to the last of October. Daylight saving time will change on the 29th. March, but there are many countries that do not change the time. Here is the full list of countries that do not introduce daylight saving time, and the reasons. Since 1996, all EU countries and Switzerland have introduced the same summer calendar, despite controversy in some member states.
Daylight saving time[1],[2] is the convention of advancing the hands of clocks by one hour during daylight saving time to extend sunlight in the late afternoon at the expense of the early morning. Both countries are crossed by the Greenwich meridian and therefore originally adopted Greenwich mean time. Daylight saving time was introduced in both states during World War I, and then used intermittently for the next two decades. The arrival of Nazi troops in both countries meant that it was used continuously throughout the year to coordinate with the Berlin clocks; After the end of World War II, the new calendar seemed useful beyond the reasons that had caused it and was therefore maintained, removing both states from their natural time zones. When the EEC began to promote the coordination of time changes throughout Western Europe in the seventies, the additional summer change meant that both countries actually had double summer time in summer. Daylight saving time takes effect on the second Sunday in March, while standard time takes effect on the first Sunday in November. As for Arizona, Navajo territories differ from the rest of the state in the use of daylight saving time. Five days before its reintroduction in 1980, a Swedish newspaper published an April Fool`s Day announcing that daylight saving time had been introduced without public notice, causing delays, confusion about the time and chaos across the country. [ref. needed] It must be said that not all countries have chosen to follow this convention, which provides for the alternation between winter time and summer time.
