The Busójárás (Hungarian, meaning Busó-walking; in Croatian: Pohod bušara) is an annual celebration of the Šokci living in the town of Mohács, Hungary, held at the end of the Carnival season (Farsang), ending the day before Ash Wednesday. The celebration features Busós (people wearing traditional masks) and includes folk music, masquerading, parades and dancing. Busójárás lasts six days, usually during February. It starts on a Thursday, followed by the Kisfarsang (Little Farsang) carnival on Friday, with the biggest celebration, Farsang vasárnap (Farsang Sunday) on the seventh Sunday before Easter Sunday; the celebration then ends with Farsangtemetés (Burial of Farsang) on the following Tuesday (Shrove Tuesday or Mardi Gras). These traditional festivities have been inscribed on the Representative List of the Intangible Cultural Heritage of Humanity of the UNESCO in 2009.
