International Jazz Day is April 30, 2014.
In November 2011, the United Nations Educational, Scientific and Cultural Organization (UNESCO) officially designated April 30 as International Jazz Day in order to highlight jazz and its diplomatic role of uniting people in all corners of the globe. International Jazz Day is chaired and led by Irina Bokova, UNESCO Director General, and legendary jazz pianist and composer Herbie Hancock, who serves as a UNESCO Ambassador for Intercultural Dialogue and Chairman of the Thelonious Monk Institute of Jazz. The Institute is the lead nonprofit organization charged with planning, promoting and producing this annual celebration.
International Jazz Day brings together communities, schools, artists, historians, academics, and jazz enthusiasts all over the world to celebrate and learn about jazz and its roots, future and impact; raise awareness of the need for intercultural dialogue and mutual understanding; and reinforce international cooperation and communication. Each year on April 30, this international art form is recognized for promoting peace, dialogue among cultures, diversity, and respect for human rights and human dignity; eradicating discrimination; promoting freedom of expression; fostering gender equality; and reinforcing the role of youth in enacting social change.
International Jazz Day is the culmination of Jazz Appreciation Month, which draws public attention to jazz and its extraordinary heritage throughout April. In December 2012, the United Nations General Assembly formally welcomed the decision by the UNESCO General Conference to proclaim April 30 as International Jazz Day. The United Nations and UNESCO now both recognize International Jazz Day on their official calendars.

 Gil Scott-Heron (born April 1, 1949) is an American poet, musician, and author known primarily for his late 1960s and early 1970s work as a spoken word soul performer and his collaborative work with musician Brian Jackson. His collaborative efforts with Jackson featured a musical fusion of jazz, blues and soul music, as well as lyrical content concerning social and political issues of the time, delivered in both rapping and melismatic vocal styles by Scott-Heron. The music of these albums, most notably Pieces of a Man and Winter in America in the early 1970s, influenced and helped engender later African-American music genres such as hip hop and neo soul. Scott-Heron’s recording work is often associated with black militant activism and has received much critical acclaim for one of his most well-known compositions “The Revolution Will Not Be Televised”. On his influence, Allmusic wrote “Scott-Heron’s unique proto-rap style influenced a generation of hip-hop artists”.
