Badnjak (Croatian pronunciation: [badɲaːk]), refers to a log brought into the house and placed on the fire on the evening of Christmas Eve, a central tradition in Croatian Christmas celebration, much like a yule log in other European traditions. In Croatian, the name for Christmas Eve is derived from the term badnjak. The log is cut with great ceremony on Christmas Eve morning, which for Roman Catholic Croats is December 24. The cutting, preparation, bringing in, and laying on the fire are surrounded by elaborate religious rituals, with many regional variations. The log is kept burning throughout Christmas Day.
With increased urbanization and migrations to cities, the badnjak tradition has recently been limited to more rural areas, as many urban homes do not have a hearth or fireplace, increasing the risk of a fire hazard, along with the fact that it is near impossible to cut one's own log in the city. Instead, some may choose to have a symbolic log kept in the home.
