The holiday falls on the third Monday of January. A bill to make Martin Luther King Jr. Day a federal holiday was introduced on April 8, 1968 — four days after King was assassinated, according to the National Museum of African American History and Culture.

Cincinnatians are encouraged to participate in these marches and programs scheduled throughout the holiday Monday.

From breakfasts, to food drives, to service projects, Massachusetts communities this weekend will celebrate Martin Luther King Jr.
