Things I love about Christmas:
Our family traditions, built up over a period of time and altering as the DC get older.
My DS Birthday is the first week, we have a Tradition of a meal out (always Carvery, his choice)
Getting out the Christmas Bedding (winter bedding until after DS Birthday then I sneak the Christmas fleeces on)
The Christmas PJs (we have Christmas Eve Hampers and DD likes winter pjs in the run up)
DH and I go shopping , we will have bought most things but this is a chance to last minute wander.
We used to have a family shopping trip but I don't think we'll do it this year (DS doesn't do shopping, DD shops are the type her Dad doesn't want to go into) 
I love the Christmas Cake - from the weighing and leaving the butter out to soften, lining the tin and the mixing. The smell of it cooking............. mmmmm then decorating with home made marzipan and icing.
Choosing a (hopefully) perfect present for someone.
And the Christmas Dinner itself. Planning the menu, prepping the veg, setting the table, the candles.
And Christmas TV. Watching those schmalzy films (where it always snows
)
And the Christmas Adverts 
I buy the Christmas magazines (usually "Good Housekeeping" "Woman & Home" and "Prima" ) but not the January issues (in Dec) because they're all full of holiday/diets/horoscopes.
So from the 1st Dec when the bedding goes on and the Advent Calenders go up, we drift through December , enjoying it.
