Since 2011, April 30 has been recognised by UNESCO as International Jazz Day, a celebration of "Jazz and its diplomatic role of uniting people in all corners of the globe." The idea to have an International Jazz Day came from jazz great Herbie Hancock, who is a UNESCO Goodwill Ambassador, and chairs the IJD committee.
The Herbie Hancock Institute of Jazz (previously the Thelonious Monk Institute of Jazz) is the lead organisational partner for International Jazz Day. Special events to promote and celebrate the day are organised in cities across the globe, with several cities designated as Official Host Cities each year, one of them hosting an all-star Global Jazz Concert.
Sydney has been designated an Official Host City for 2019. The day will be celebrated in Melbourne, with a show featuring special guest performers onstage at Bird's Basement.
