As most Americans know, Monday, January 21 is Rev. Dr. Martin Luther King Jr. Day, a federal holiday that celebrates Dr. King's life and work. The holiday is observed every third Monday in January. I was recently reminded that although the holiday was signed into law in 1983, the day took on an even deeper meaning eleven years later. In 1994 Congress named Martin Luther King Jr. Day a national day of service. Since then, many Americans celebrate the day through some kind of community volunteerism and/or public service.
