Saint Lucia's Day is celebrated on December 13th each year, primarily in Sweden and other parts of Scandinavia. The festival honors Saint Lucia, a Christian martyr known for her kindness and light. During the celebration, a girl is chosen to represent Lucia, wearing a white gown and a crown of candles, symbolizing the return of light during the dark winter months. The day is marked by various traditions, including singing Lucia songs and serving special treats like saffron buns. Communities often hold processions, where the Lucia figure leads a group of girls and boys dressed in white, creating a festive atmosphere that highlights the importance of light and hope.
