G. K. Chesterton 
Christmas and Other Stories 

There is no more dangerous or disgusting habit than that of celebrating Christmas before it comes, as I am doing in this article. It is the very essence of a festival that it breaks upon one brilliantly and abruptly, that at one moment the great day is not and the next moment the great day is. Up to a certain specific instant you are feeling ordinary and sad; for it is only Wednesday. At the next moment your heart leaps up and your soul and body dance together like lovers; for in one burst and blaze it has become Thursday.
