Martin Luther King Jr. Day is an American national holiday celebrating the birthday of Martin Luther King, Jr. It is celebrated on the third Monday of January each year, which is around the time of King’s birthday, January 15. King was the leader in nonviolent protest against racial discrimination in federal and state law. The campaign for a federal holiday in King’s honor began soon after his assassination in 1968. President Ronald Reagan signed the holiday into law in 1983. In observation of the holiday, campus offices will be closed. There will be no classes on this day.
