Piano Day is an international piano celebration day, on the 88th calendar day, symbolizing 88 standard piano keys.
In Copenhagen in 2026 it has been organized by Nadia Okrusko in collaboration with pianists Matt Choboter and Margaux Oswald, and featured a guest pianist from Lithuania, Marta Finkelstein.
The project has been supported by Knud Højgaard fond, Dansk Musiker Forbund, Nørrebro Lokaludvag, Art Music Denmark and Københavns Kommune.
