One of the hardest clean up jobs after the holiday is taking down the Christmas tree. Tradition would dictate the time to be twelve days after Christmas or Twelfth Night. It is considered bad luck if you leave it up any longer. You are the one to decide the best time to take disassemble the tree or put it to the curb. It is a time consuming job to take off and carefully wrap your ornaments, take the lights off, etc. In a year, it will start all over again. Hope you had a joyous holiday.
