Four Days in December (also listed as 4 Days in December) was a four-day festival of new jazz music that took place at Judson Hall in New York City. Sponsored by the Jazz Composers Guild, it occurred from December 28–31, 1964, and was the group's most visible event. Along with the October Revolution in Jazz, held two months prior and organized by Bill Dixon, it led to a sense of optimism regarding the possibility of producing concerts via non-traditional means.
