Roma of the Orthodox faith living in Serbia celebrate Bibija as the protector saint of the family, and above all as the protector of children's health. Each town or city has its own special date of celebration, which is explained by the legend of Aunt Bibija, who arrived to different places on different dates and performed healings. The dates for celebrating this Romani holiday are mostly related to the days of Easter Lent, so they are movable.
Bibija is celebrated collectively so that all members of Roma community gather at a holy place - usually, a tree or a cross, bringing a celebration cake and food, and in some parts gifts for Bibija (comb, mirror and children's clothes) which they hang on the sacred tree. In some urban areas, participants gather in restaurants and hotels. The celebration is organized by the Host of Bibija, and the presence of an Orthodox priest is obligatory at the celebration, although Aunt Bibija was not a canonized saint.
