When is Warsaw Uprising Day?
In 2026, Warsaw Uprising Day falls on Saturday, August 1, 2026. It is an observance rather than a federal holiday, so federal offices and most businesses follow their normal schedules.
History of Warsaw Uprising Day
The Warsaw Uprising began on 1 August 1944, when the Polish underground Home Army launched an attempt to liberate Warsaw from German occupation as the Soviet front approached. The planned short operation became a 63-day battle fought amid catastrophic civilian suffering and the destruction of much of the city.
Poland observes the anniversary as the National Day of Remembrance of the Warsaw Uprising, not as a statutory day off. At 5 p.m.—the uprising's 'W hour'—sirens sound in Warsaw and many people pause. The ritual is brief but powerful, joining individual memory to a wider reckoning with courage, loss and the city's post-war rebuilding.
Warsaw Uprising Day remembers a Home Army operation that began at 17:00 on 1 August 1944 as Soviet forces approached from the east. Insurgents sought to liberate the capital before Soviet-backed authorities could impose control, but they lacked heavy weapons and expected help that did not arrive on the necessary scale. German forces committed mass atrocities, including the Wola massacre, and systematically destroyed the city after the surrender on 2 October. Approximately 63 days of fighting made civilian experience inseparable from military memory. Poland established the National Day of Remembrance in 2009; the law created a commemorative holiday, not a nationwide day free from work.
