National Uprising Day in Slovakia, officially known as the Slovak National Uprising Anniversary, is celebrated on August 29 each year. This day honors the commencement of a major military and political event in Slovak history - the Slovak National Uprising against Nazi Germany occupation during World War II.

The uprising began on August 29, 1944, led by the Slovak resistance movement. Despite being suppressed by Nazi forces in October 1944, it symbolized a significant demonstration of solidarity against oppressive regimes and is considered a symbol of national pride.

On National Uprising Day, various commemorative events take place across Slovakia. The main celebrations are usually held in Banská Bystrica, the center of resistance during the uprising. Activities typically include laying wreaths at memorials, military parades, exhibitions related to wartime history and various cultural performances.

Schools and public offices remain closed as it's a national holiday, while citizens often spend time learning about their nation's history or visiting monuments associated with the uprising. The day serves as a reminder of bravery and unity demonstrated by Slovaks during difficult times in history.
