Boxing up Christmas

We would have boxed it up a couple weekends ago; but we went to visit the grandparents who came to visit in CLT, and this weekend was busy with ballet class, I AM LEGEND,  NO COUNTRY FOR OLD MEN, and rehearsal.

We did take down the outside decor and lights last weekend upon returning from CLT. There are a few neighbors who still have their lights up and on all the time…

 What is the cut off date?
