Good Day!
Well, there is Kwanzaa, which begins the day after Christmas. There is Music Month in June. Dr. Martin Luther King Jr. Day. Also, Juneteenth (The African American Independence Day) which very few people observe anymore. But a few people do. Of course there is Women's History Month in March. The holiday of Jonkonnu (Jonkonnu is a festival with roots in Caribbean, West African, and English traditions, originally celebrated in the U.S. by African Americans in the 19th century.
Traditionally, revelers celebrated by singing and dancing to the beats of a drum called a gumba box. The dancers paraded from house to house and collected coins�usually from white slave-owners. At the end of the performance, a costumed ragman�the leader of the revelers�shook hands with the slaves' master.
Hope that helps!
