When is Silesian Uprisings Day?
In 2026, Silesian Uprisings Day falls on Saturday, June 20, 2026. It is an observance rather than a federal holiday, so federal offices and most businesses follow their normal schedules.
History of Silesian Uprisings Day
The National Day of the Silesian Uprisings remembers three armed struggles in Upper Silesia between 1919 and 1921, fought amid competing Polish and German claims after the First World War. The uprisings, the 1921 plebiscite and subsequent international decisions shaped the division of the industrial region and the incorporation of part of Upper Silesia into the reborn Polish Republic.
Parliament established the state observance in 2022. June 20 recalls the ceremonial entry of Polish troops under General Stanisław Szeptycki into Katowice in 1922, rather than the outbreak date of any one uprising. The day honours insurgents and residents whose political, cultural and military efforts influenced the border settlement. It is an official state holiday in the commemorative sense, but it was not added to the Act on Non-Working Days.
The choice of June 20 gives Silesian Uprisings Day a deliberately regional centre within a national calendar. Katowice, Góra Świętej Anny and towns across the Upper Silesian industrial district host memorial ceremonies, exhibitions and discussions about the three uprisings' differing causes and outcomes. Responsible interpretation also addresses the 1921 plebiscite, international administration and the region's Polish-, German- and Silesian-speaking communities. The observance honours those who fought for attachment to Poland without turning a contested borderland into a one-dimensional story. Because the founding 2022 act calls it a state holiday but does not amend the non-working-days statute, schools and workplaces follow normal schedules.
How Silesian Uprisings Day is observed
A nationwide state observance on June 20, not a statutory day off. Ceremonies are concentrated in Katowice and other Upper Silesian communities; normal working schedules apply. This state or national observance is not listed in the Act on Non-Working Days, creates no general retail closure and does not alter ordinary working-time schedules.
