In my family, Christmas Day tends to follow the same pattern. Early rising to open presents, then a big Christmas lunch, and then an afternoon spent wondering why there isn't any decent sport on TV.
Now the lack of sport on Christmas Day wasn't always so. For example Australia got rolled by the West Indies back in 1951, with the final days play being the 25th of December.
Of course having to play on Christmas Day may be an inconvenience to some, but to others it is just another day (at least culturally and religiously). Last year the Asian Clubs Championship was run over the Christmas period, which probably inconvenienced some teams. However it still got a good turn out, and there was even a round held on the 25th. Here is a game played on that day, resulting in a crisp win to Indian player Deep Sengupta.
