On January 18, 1993, for the first time, Martin Luther King Day was officially observed in all 50 U.S. states. The day is marked by demonstrations for peace, social justice and racial and class equality, as well as a national "day on" of volunteer community service.
Although the day is a federal holiday and a state holiday in all states, it is usually not observed by small private companies. Large corporations are usually closed, but small shops, restaurants, Grocery Stores remain open. Additionally most schools and places of higher education are closed for classes, but may hold seminars or celebrations of Dr. King's message.
