Summer time in Europe: Difference between revisions

'''Summer time in Europe''' is the variation of standard clock time that is applied in most [[Europe]]an countries (apart from [[Iceland]], [[Belarus]], [[Turkey]], [[Ukraine]] and [[Russia]]) in the period between spring and autumn, during which clocks are advanced by one hour from the time observed in the rest of the year, with a view to making the most efficient use of seasonal daylight. It corresponds to the notion and practice of [[daylight saving time]] (DST) to be found in some other parts of the world.

In all locations in Europe where summer time is observed (the [[EU]], [[EFTA]] and associated countries), '''European Summer Time''' begins at 01:00 [[UTC]]/[[Western European Time|WET]] (02:00 [[Central European Time|CET]], 03:00 [[Eastern European Time|EET]]) on the last Sunday in March (between 25 ~and 31 March) and ends at 01:00 UTC (02:00 [[Western European Summer Time|WEST]], 03:00 [[Central European Summer Time|CEST]], 04:00 [[Eastern European Summer Time|EEST]]) on the last Sunday in October (between 25 ~and 31 October) each year; i.e. the change is made at the same absolute time across all time zones. [[European Union Directive]] 2000/84/EC makes the observance of summer time mandatory for EU member states (except overseas territories), though. aA proposal to repeal this directive and require that member states observe their own choice{{notetag|The choice should be either summer or winter time of their current time zone; however, this is not obligatory, so a new time zone could be chosen as well.}} year-round is currently going through the legislative process {{As of|July 2020|lc=y}}, but has not seen progress since October 2020.<ref>{{cite news |last1=Lawson |first1=Patrick |title=The plan to abolish the time change is "completely blocked" at European level, says specialist in European issues |url=https://www.geads.co.uk/2020/10/25/the-plan-to-remove-the-time-change-is-completely-blocked-at-european-level-says-specialist-in-european-issues/ |archive-url= https://web.archive.org/web/20210212075621/https://www.geads.co.uk/2020/10/25/the-plan-to-remove-the-time-change-is-completely-blocked-at-european-level-says-specialist-in-european-issues/|work=Geads News |date=18 November 2020|archive-date=12 February 2021|url-status=dead}}</ref>

[[Büsingen am Hochrhein]], a small exclave of Germany entirely surrounded by Swiss territory, did not implement summer time in 1980 but observed the same time as Switzerland; thus there was a one-hour time difference between this village and the rest of [[Germany]].

In the [[Republic of Ireland|Ireland]], so called [[Irish Standard Time]] (IST) (UTC+01, [[Western European Summer Time]]) is observed during Summer (March to October). IST is sometimes mistaken for "Irish Summer Time", though this is incorrect. Winter Time (UTC+00, [[Western European Time|WET]]) is observed in the rest of the year.

A decree of the [[Russian Provisional Government]] introduced summer time ({{lang-langx|ru|летнее время}}) in [[Russia]] on 1 July 1917, and clocks moved one hour forward. A [[Soviet Decrees|decree]] of the [[Sovnarkom|Soviet government]] led to the abandonment of this system six months later: clocks moved one hour back again on 28 December.<ref>{{cite web|url=http://www.timeanddate.com/time/zone/russia/moscow?year=1916|title=Time Zone & Clock Changes 1900-1924 in Moscow, Russia|website=www.timeanddate.com}}</ref>

On 3 March 2021, the Verkhovna Rada voted on bill No. 4201 «"Draft Law on time observation in Ukraine»" which, if accepted in the second reading in March 2021, will abandon transitioning to summer time and establish year-round standard time ([[UTC+02:00]]) on the whole territory of Ukraine.
