International Jazz Day
UNESCO 36 C/Resolution 39
UNESCO 36 C/Resolution 39
This authority record treats the observance as a fixed annual date. The same month and day can be reused unless a stronger source changes the rule. Public-holiday or government status is never inferred from the observance name alone.
Overview
International Jazz Day is observed on 30 April. UNESCO proclaimed the day in 2011 to highlight jazz as an artistic form and as a means of dialogue, education, cooperation and mutual understanding.
The observance is about more than concerts. UNESCO frames jazz in relation to cultural expression, dignity, inclusion and exchange across communities, while annual host-city details and programmes remain refreshable.
Why it matters
Jazz developed through complex histories of African American musical creativity and later became a global form with many regional traditions. A useful observance guide should recognize that history without flattening jazz into one style, place or era.
The day can support listening, performance, education and discussion of how improvisation, collaboration and cultural exchange operate in music.
History
After becoming a UNESCO Goodwill Ambassador in 2011, Herbie Hancock proposed a global jazz project; UNESCO identifies his initiative as the origin of International Jazz Day.
UNESCO’s General Conference proclaimed 30 April as International Jazz Day on 10 November 2011, and the first celebration took place on 30 April 2012.
On 17 December 2012, the UN General Assembly welcomed UNESCO’s proclamation through A/RES/67/106 and called on Member States to participate actively. Current UNESCO materials describe the Herbie Hancock Institute of Jazz as managing the Day in coordination with UNESCO.

Ways to observe
Listen to recordings from different periods and regions and compare how instrumentation, rhythm and improvisation change.
Attend a school, library, community or venue programme that credits the musicians and historical context accurately.
Learn about the local history of jazz where you live rather than assuming the same development everywhere.
Use musician interviews, archives or reputable music institutions when exploring disputed or complex history.
If organizing a performance, handle music licensing, venue rules and performer permissions separately from the observance itself.

Is International Jazz Day an official public holiday?

Who established or recognizes International Jazz Day?

Is International Jazz Day international or country-specific?

Is International Jazz Day only a concert event?

These distinctions are separately reviewed and source-backed. They clarify scope; they do not change either authority record.
Is International Jazz Day the same as World Art Day?
