National Unity and Armed Forces Day is an Italian national day since 1919 which commemorates the victory in World War I, a war event considered the completion of the process of unification of Italy. It is celebrated every 4 November, which is the anniversary of the armistice of Villa Giusti becoming effective in 1918 declaring Austria-Hungary's surrender.
