When is Martin Luther King Jr Day?
Martin Luther King Jr Day is an annual holiday to mark the birthday of the former American Baptist minister and civil rights activist, held in his name.
He was born on 15 January 1929 in Atlanta, Georgia.

This year, Martin Luther King Jr Day will take place on Monday 18 January.
Many observe the day by volunteering in the community or for local charities. Barack Obama served lunch at Washington soup kitchen on MLK Day in 2010.
