Inauguration Day
Observed only by federal government employees in Washington D.C., and the border counties of Maryland and Virginia, in order to relieve congestion that occurs with this major event. Swearing-in of President of the United States and Vice President of the United States. Celebrated every fourth year. Note: Takes place on January 21 if the 20th is a Sunday (although the President is still privately inaugurated on the 20th). If Inauguration Day falls on a Saturday or a Sunday, the preceding Friday or following Monday is not a Federal Holiday
