Christmas Party

Well our windows are getting replaced today so I am off this computer shortly but here is a question for you.

We are having our Christmas party as a big buffet before we start work at 5 that evening on the 20th. It is a family thing with Santa there and everything. My wife however always has hers' after Christmas.

I prefer it before Christmas no matter how busy it is.

Assuming your employer holds a party for Christmas do you prefer it after the rush in January or in December when the holiday spirit is still around us?
