Aviation Day is observed in Slovenia every August 2, honoring the personnel of the Slovenian Air Force and Air Defense, which is part of the army rather than an independent branch. This professional holiday commemorates the establishment of an aviation department in each division of the army, ordered by King Alexander I of Serbia in 1893. The celebration includes ceremonies attended by the Minister of Defense and other officials, with the main event taking place at the Batajnica Air Base near Belgrade. The Slovenian Air Force and Air Defense is tasked with securing the country's airspace, providing air support for joint operations, and assisting in disaster response and search and rescue missions.
