I have penciled in my calendar to set up the tree next Monday 10, December for no other reason then that my other half is off that day and it's easier with two. If you decorate when do you put your tree up? How long do you leave it up?
In many areas, it has become customary to set up one's Christmas tree at the beginning of the Advent season. Some families in the U.S. and Canada will put up a Christmas tree soon after American Thanksgiving (the 4th Thursday of November) Some households do not put up the tree until the second week of December, and leave it up until 6 January (Epiphany). In Germany, traditionally the tree is put up on 24 December and taken down on 7 January, though many start one or two weeks earlier, and in Roman Catholic homes the tree may be kept until late January.
In Italy and Argentina, along with many countries in Latin America, the Christmas tree is put up on 8 December (Immaculate Conception day) and left up until 6 January. In Australia, the Christmas tree is usually put up on 1 December which occurs about a week before the school summer holidays; except for South Australia, where most people put up their tree after the Adelaide Christmas Pageant in late November. Some traditions suggest that Christmas trees may be kept up until no later than 2 February, the feast of the Presentation of Jesus in the Temple, when the Christmas season effectively closes. Superstitions say that it is a bad sign if Christmas greenery is not removed by Candlemas Eve.
We usually take our tree down on 7, January.
