The King's Feast (Dutch: Koningsfeest, French: Fête du Roi) is celebrated in Belgium on November 15, since 1866. On this day, since 2001, the Belgian Federal Parliament holds a ceremony in honour of the King, in the presence of members of the Belgian Royal Family and dignitaries. Federal ministries are closed on this day. Traditionally, a Te Deum is sung on this day as well as a private occasion.
November 15 is the name day of Leopold (in the German liturgical calendar, it is the feast of Saint Leopold) and Albert (in the General Roman Calendar, it is the feast of Saint Albert the Great). King Baudouin in 1951 decided to keep this date, as did his brother King Albert II. During the regency of Prince Charles, the names Day of the Dynasty or Feast of the Dynasty were used, and these names are still often erroneously used nowadays. However it is not the correct name, as was confirmed in a circular letter in 1953.
