Martin Luther King Jr. Day

Martin Luther King Jr. Day is a federal holiday on the third Monday in January, honoring the Baptist minister and civil rights leader born in Atlanta on January 15, 1929. President Ronald Reagan signed the holiday into law on November 2, 1983, and Americans first observed it on January 20, 1986. Federal law still lists it by its formal name, the Birthday of Martin Luther King, Jr.

Whom MLK Day Honors

King was a leading voice of the nonviolent civil rights movement of the 1950s and 1960s. He was a leading figure at the 1963 March on Washington and received the Nobel Peace Prize in 1964, when he was 35. He was assassinated in Memphis, Tennessee, on April 4, 1968.

The holiday is one of only two federal holidays created for the birthday of an individual American. The other is Washington’s Birthday, better known as Presidents’ Day. Federal law ties neither holiday to the exact birth date, which is why both move around the calendar.

MLK Day History: A 15-Year Campaign

The push began almost immediately. Rep. John Conyers of Michigan introduced a bill for a national King holiday four days after the assassination, and Sen. Edward Brooke of Massachusetts backed the idea in the Senate. Congress did not act on it for years.

Supporters kept up the pressure:

• Early 1970s: The Southern Christian Leadership Conference gathered petitions carrying about 3 million signatures.
• 1973: Illinois became the first state to adopt a King holiday. Massachusetts and Connecticut followed in 1974.
• 1979: Coretta Scott King testified before Congress in support of the bill. In November the House voted 252 to 133 for it, short of the two-thirds majority required under the suspension-of-the-rules procedure being used.
• 1980: Stevie Wonder released the album Hotter than July, including “Happy Birthday,” a song written to promote the holiday campaign.
• January 15, 1983: More than 100,000 people rallied at the Washington Monument.

By the time Congress voted again, petitions had collected more than 6 million signatures. The House passed the holiday bill 338 to 90 on August 2, 1983, a few weeks before the 20th anniversary of the March on Washington. The Senate followed 78 to 22 on October 19. Both margins were large enough to override a veto, and Reagan signed the measure on November 2, 1983, as Public Law 98-144.

The law took effect on January 1, 1986, so the first national observance came on Monday, January 20, 1986, more than two years after the signing.

When Is MLK Day 2027? How the Date Is Set

The rule is the third Monday in January. Congress chose a Monday, rather than King’s January 15 birthday, to match the Monday holiday system set by the Uniform Monday Holiday Act of 1968.

The third Monday of any month falls between the 15th and the 21st. That means MLK Day lands on King’s real birthday only when January 15 is itself a Monday, as it was in 2024 and will be again in 2029. The latest possible date is January 21.

MLK Day 2027 falls on Monday, January 18. You can see it alongside the other winter holidays on the 2027 calendar. The table below this article lists the date for every year from 1990 to 2035.

Because the holiday is defined as a Monday, the federal Saturday and Sunday substitution rule never comes into play. That rule matters for fixed-date holidays such as New Year’s Day, which can land on a weekend.

When MLK Day meets Inauguration Day

Every fourth January, MLK Day and Inauguration Day fall close together, and sometimes on the same Monday. When January 20 falls on the third Monday, they coincide, as in 1997 and 2025. In 2013, January 20 was a Sunday, so the public inauguration moved to Monday, January 21, which was also MLK Day. The 2025 calendar shows the most recent overlap.

The States: From Illinois in 1973 to South Carolina in 2000

Federal law sets holidays for federal employees and offices, not for state governments. Each state decided on its own, and the timeline stretched for more than a decade after the first federal observance. By January 1989, 44 states marked a King holiday.

Arizona’s path drew national attention. Gov. Bruce Babbitt created a paid state holiday by executive order in 1986, and his successor, Gov. Evan Mecham, rescinded it in 1987. Arizona voters rejected holiday measures in November 1990, and the NFL moved Super Bowl XXVII out of the state. Voters approved the holiday in a 1992 referendum.

New Hampshire created a Civil Rights Day in 1991 and renamed it for King in 1999. South Carolina made the day a paid holiday for all state employees in May 2000, completing recognition across the states.

Names still vary. Alabama and Mississippi combine the day with an observance of Robert E. Lee’s birthday. Arkansas did the same until 2017, when it moved the Lee observance to October.

A Day On: How the MLK Day of Service Began

In 1994 Congress gave the holiday a second purpose. The King Holiday and Service Act, sponsored by Sen. Harris Wofford and Rep. John Lewis and signed by President Bill Clinton on August 23, 1994, encouraged Americans to mark the day through volunteer work. The goals included community service, cooperation among people of different races and backgrounds, and programs for young people.

AmeriCorps, the federal agency for national service, leads the national effort. It treats MLK Day as one of two national days of service, alongside the September 11 anniversary that is also observed as Patriot Day.

How Americans Observe Martin Luther King Jr. Day

Observances mix remembrance, worship and work. Common ways people take part include:

• Volunteer projects such as food drives, school cleanups and neighborhood repairs
• Church services, commemorative breakfasts and interfaith programs
• Marches, parades and public readings of King’s speeches and writings
• School lessons on the civil rights movement in the days before the holiday

The day also changes the business calendar. Federal offices close, as do the New York Stock Exchange and Nasdaq, and banks generally close as well. Schools and private employers make their own decisions, so the holiday can be a full day off in one household and a normal workday next door.

MLK Day Facts Worth Knowing

• Earliest and latest dates: January 15 to January 21.
• First observance: Monday, January 20, 1986, more than two years after the law was signed.
• Last state to make it a paid holiday for all state employees: South Carolina, in 2000.
• Most recent new federal holiday before 2021: MLK Day held that place until Juneteenth was added in 2021.
• The 1979 vote: The House majority that year was large, 252 to 133, but still short of the two-thirds required by the procedure used.

How the Holiday Has Changed Over Time

MLK Day began as a contested proposal that took 15 years to pass Congress and another 14 years to reach every state. Even after 1986, the Arizona and New Hampshire debates show that some states argued over whether to hold the holiday and what to call it.

Since 1994, the emphasis has shifted toward service. The federal date rule has not changed since the first observance in 1986: the third Monday in January, within a week of the birthday it honors.
