Federal and state offices, banks, as well as postal and trash services will be closed or suspended Monday. Here’s what else you should know.

It’s rare for the two federal holidays to overlap, and this is just the third time in history that a president will take the oath of office on MLK Day.

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.
