Koledari are people who go around visiting houses and singing songs during the Christmas season. These songs are about the birth of Jesus and wishing people good luck for the coming year. The Koledari wear traditional costumes and travel in groups. They can be young or old, male or female. Think of it like going on a Christmas caroling adventure with your friends and family but with a special outfit and some extra meaning to the songs. The Koledari are said to bring luck to the homes they visit and receive gifts or treats in return for their songs. So, it's a nice way to spread holiday cheer and partake in Christmas traditions.
