January 15, 2018, All Day
Martin Luther King Jr. Day (official Birthday of Martin Luther King, Jr.) is an American federal holiday marking the birthday of Martin Luther King Jr. It is observed on the third Monday of January each year, which is around King's birthday, January 15. The holiday is similar to holidays set under the Uniform Monday Holiday Act.
King was the chief spokesman for nonviolent activism in the Civil Rights Movement, which successfully protested racial discrimination in federal and state law. The campaign for a federal holiday in King's honor began soon after his assassination in 1968. President Ronald Reagan signed the holiday into law in 1983, and it was first observed three years later. It was officially observed in all 50 states for the first time in 2000.
