Serbia. Vojvodina (Војводина). South Banat District (Јужнобанатски). Vršac (Вршац). On the thrid day of Serbian Orthodox Christmas in Vršac, the badnjak ("Christmas straw") is burned. It officially ends Christmas. There are regional variations of this tradition, as well as house-hold variations. At @jov_anja
's house, apparently, we burn it on Serbian Orthodox Christmas Eve.
