Labor Day, also known as International Workers' Day, is a significant holiday in Slovenia. Celebrated annually on the 1st and 2nd of May, this holiday signifies the struggle for workers' rights and pays tribute to the working class and laborers. It represents a day of rest and relaxation for the hardworking citizens of the country, serving as a mark of respect for the labor movement and an acknowledgment of its significant contributions to society.

The holiday in Slovenia is filled with unique traditions and festive celebrations. One such tradition is the erection of the 'maypole' or 'maibaum', a decorated tree or pole that is set up on village squares and is considered to be a symbol of prosperity and fertility. Concerts, bonfires, family gatherings, and communal meals are other essential components of the Labor Day celebrations in Slovenia. The festivities kick off the night before, on 'Walpurgis Night', with bonfires lit to chase away evil spirits.

In addition to its labor significance, Labor Day in Slovenia also marks the beginning of spring and is associated with a host of leisure activities. It's a time when people engage in outdoor activities, barbecue parties, hikes, and trips to the countryside. The holiday is also a part of the extended May Day holidays, which include the Day of Resistance against Occupation, celebrated on April 27, and Victory Day, celebrated on May 9, making it a long period of celebration and relaxation for the Slovenians.
