Martin Luther King Jr. Day is always celebrated on the third Monday in January. It also happens to be Inauguration Day, which is always held on January 20th per the U.S. Constitution. The two typically don’t coincide, but they just so happen to fall on the same day this year.

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.
