Christmas is both a sacred religious holiday and a worldwide cultural and commercial phenomenon. For two millennia, people around the world have been observing it with traditions and practices that are both religious and secular in nature. Christians celebrate Christmas Day as the anniversary of the birth of Jesus of Nazareth, a spiritual leader whose teachings form the basis of their religion. Popular customs include exchanging gifts, decorating Christmas trees, attending church, sharing meals with family and friends and, of course, waiting for Santa Claus to arrive. December 25–Christmas Day–has been a federal holiday in the United States since 1870.

Around Christmas time in Sweden, one of the biggest celebrations is St. Lucia's Day (or St. Lucy's Day) on December 13th. The celebration comes from stories that were told by Monks who first brought Christianity to Sweden.

St Lucia was a young Christian girl who was martyred, killed for her faith, in 304. The most common story told about St Lucia is that she would secretly bring food to the persecuted Christians in Rome, who lived in hiding in the catacombs under the city. She would wear candles on her head so she had both her hands free to carry things. Lucy means 'light' so this is a very appropriate name.

December 13th was also the Winter Solstice, the shortest day of the year, in the old 'Julian' Calendar and a pagan festival of lights in Sweden was turned into St. Lucia's Day.

St. Lucia's Day is now celebrated by a girl dressing in a white dress with a red sash round her waist and a crown of candles on her head. Small children use electric candles but from about 12 years old, real candles are used!
