Right after our town's Santa Claus parade is when I put up the outdoor stuff (we don't have a big front yard, but we light it up). Then the first Sunday of Advent is the day I put up the indoor stuff. The day before I hold a children's Christmas party where we make ornaments and get everybody in the Christmas mood. Sometimes I'll put up a bit of Christmas stuff, but usually it all comes out on the Sunday because I need the extra room in the house for all the party-goers.
