World Accordion Day (WAD) 2024 and earlier years Event Reports. Since 2009, each May 6th, the CIA has been promoting World Accordion Day.

Our first WAD was held on 6th May 2009, marking the 180th birthday of the accordion – 6 May 1829, the date the accordion patent was filed.

On May 6, 1829, Cyrill Demian (1772–1849) an organ and piano maker of Armenian origin, accompanied by his two sons Karl and Guido, filed a patent in Vienna, Austria for the accordion.

Since 2009, WAD has been very successful, generating a lot of positive publicity for the accordion.

Everyone can register their WAD activity on the website and send a report of their event after for the website. World Accordion Day (WAD)
