Advent calendars and wreaths are important traditions in Germany during Advent leading up to Christmas. Germans also enjoy visiting Christmas markets, where various foods and decorations like glass ornaments are sold. Christmas trees hold special significance as well, often being decorated in secret by mothers, and brought indoors on Christmas Eve to read the Bible and sing carols by. The main presents are delivered on December 24th by either Santa Claus, Father Christmas, or Christkind, depending on the region of Germany.
