The Day of Serbian Unity, Freedom and the National Flag is a national holiday celebrated on September 15 in Serbia and the Bosnian entity Republika Srpska.
The holiday was established to be celebrated on the day when the Breakthrough of the Thessaloniki Front in the First World War is commemorated, and it has been celebrated since 2020.
The idea of establishing a joint holiday between Serbia and the Republika Srpska was brought to the public after the meeting between the President of Serbia, Aleksandar Vučić, and the Prime Minister of Serbia, Ana Brnabić, with the leadership of the Republika Srpska in August 2020.
