Martin Luther King Jr.Martin Luther King Jr Day is observed in the US on the third Monday of January each year. It honors the legacy and memory of civil rights leader Rev. Dr. Martin Luther King Jr., whose actual birthday is Jan. 15. Learn more about King at the King Center website or Wikipedia.
MLK Jr. Day became a federal holiday in 1983, but not all states recognized the day right away.
How long each state has recognized MLK Jr. Day.
New Hampshire and Utah waited until 1999 and 2000, respectively. Some states, like Connecticut and Illinois, were trailblazers, recognizing the day a decade earlier, in 1973. One state, Arizona, has the unique dishonor of recognizing it in 1986 and then de-recognizing it a year later! Arizona later re-recognized the day by referendum in 1992.
Timeline of state recognition of MLK Jr. Day.
The road to 50-state recognition.I (@arati_mejdal) posted a set of four data visualizations at JMP Public, with the help of @XanGregg and @Peter_Polito: a bubble plot, map, bar graph and line graph. Each visualization highlights a different aspect of the story of state recognition of the day. The bubble plot, for instance, shows the flip-flopping of Arizona on this issue.
Check out the visualizations and also let us know, if you're in the US, how you are planning to mark MLK Jr. Day.
