In Poland, the standard time is Central European Time (Polish: Czas środkowoeuropejski; CET; UTC+01:00).[1] Daylight saving time is observed from the last Sunday in March (02:00 CET) to the last Sunday in October (03:00 CEST).[2]

History

In the early nineteenth century, Poland observed UTC+01:24 as it was the time corresponding to the offset of their local mean time at the Warsaw meridian, which was also known as Warsaw mean time.[3] This was commonly used for timekeeping purposes in the lands of the former Polish–Lithuanian Commonwealth.[4][5]

Poland adopted CET on 31 May 1922.[6][7] After World War II, summer time in Poland was introduced in 1946 by a resolution of the Council of Ministers, though it would later be repealed on 21 September 1949.[8][9] on the application of Central European Time in the territory of the State. Summer time was in use again between 1957 and 1964, and has been in use since 1977.[5][10]

In Poland, consultations were carried out regarding the time shift, which showed 78 percent of Poles were not in favour of summer time.[11] Despite this, however, it is not yet known whether the last time change in Poland will occur in 2021, as there are currently no legal regulations yet.[12]

Notation

Main article: Date and time notation in Poland

The 12-hour clock is commonly used in speech when unambiguous, with the AM/PM distinction denoted by phrases in Polish when needed; written communication uses 24-hour clock almost universally, including written forms of informal speech.

IANA time zone database

In the IANA time zone database, Poland is given one zone in the file zone.tab – Europe/Warsaw. Data for Poland directly from zone.tab of the IANA time zone database; columns marked with * are the columns from zone.tab itself:
