I have just started but so far I have:
Sunday 27th November - decorating our home, everything but the Christmas tree, children turn on the first candle on advent wreath at 7 pm (and repeat that every sunday till Christmas till all the candles are lit)
Thursday 1st December - advent calendars are out - one for each child, they are refillable with chocolates and activities for some days. Each child gets his and hers christmas activity book, we start our christmas jigsaw puzzle that will hopefully be finished by Christmas say (or at least January 8th), we bring back to light all our christmas stories and read one every evening till januray the 6th. This year I would like us to finish till Chrismas Jostein Gaarder's Advent Calendar but I think that is just wishful thinking on my side
Tuesday 6th December - St. Nicholas Day, children open their stockings. As you can see I'm not british so Christmas stockings (or boots) come earlier in my country. Children usually get just chocolate, but being an avid mumsnetter I couldn't help myself and mine are a bit more elaborate so I put Christmas socks, a magazine to each, a little toy I know they would like... My friends would think I'm crazy for spoiling my kids, so I do not talk about that. I have to say it is my dream to have a proper british christmas so I can have a proper stocking on Christmas morning
I have very funny working schedule, I work most weekends, and when I'm free it is in the middle of the week so, my schedule probably looks funny to most people.
Wednesday 7th December - decorating christmas tree at 6 pm with christmas songs. It lasts at least 5 hours till we're done.
Thursay 8th December - start of baking season with kids - stamp cookies with lemon, oatmeal cookies with chocolate (make double batch and put one half to freezer).
I'm buying presents online or in a shop after work, and I wrap them as I go (while children sleep) and keep them under the christmas tree until Christmas Day or until I have to ship them.
So, that's just the beginning. How does your christmas schedule looks like?
