Inauguration festivities come a close in the evening of the day in which the swearing-in ceremony takes place. To celebrate, a multitude of galas are held in Washington, D.C. to honor the President and to mark the historic occasion. Inaugural balls are divided into two categories: official balls and unofficial balls. The number of official balls varies but is limited (two were held in 2013, and ten in 2009), and the President traditionally makes appearances at these events. The number of unofficial balls also varies, but can be quite large (over 100 in 2009). Unofficial balls are hosted by private organizations, such as companies and state societies.
