Because so many people, especially in the United States, treat the Advent season as the "Christmas season," however, the actual Christmas season gets lost. By the time Christmas Day comes, people are ready to pack up the decorations, and the tree--which they might have put us as early as Thanksgiving weekend--is probably past its prime.
If we were to revive the older tradition of putting up the Christmas tree and decorations closer to Christmas (see "When Should You Put Up Your Christmas Tree?"), then we could celebrate Advent to its fullest--and in keeping our decorations up after Christmas Day, we might find a renewed sense of joy in celebrating all twelve days of Christmas.
