In Germany, Christmas is celebrated with a variety of traditions and customs. Many families put up a Christmas tree, decorate it with lights and ornaments, and hang stockings on the fireplace mantle. On Christmas Eve, children are told that Santa Claus, known as "der Weihnachtsmann," will visit while they're sleeping and leave gifts under the tree. Families often gather for a festive dinner and exchange gifts. On Christmas Day, children wake up to find presents under the tree and spend the day playing with their new toys. Many families also attend a special church service on Christmas Eve or Christmas Day to celebrate the birth of Jesus.
