National Disc Jockey Day, also known as National DJ Day, is observed every January 20 in the USA. This day celebrates all DJs and pays tribute to Alan “Moondog” Freed, a significant American disc jockey from the 1950s, who was instrumental in popularizing rock and roll and breaking down racial barriers in the music industry. The term "disc jockey" was first coined by Walter Winchell to describe Martin Block, a pioneer in playing recorded music on the radio. Celebrations typically include learning about the history of DJing, giving shout-outs to favorite DJs on social media, listening to radio shows, visiting clubs, and even trying one's hand at mixing tracks. Alan Freed's legacy is honored on this day, as he is remembered for his contributions to music and his promotion of African-American artists.
