As a number of writers have noted previously, sales of Christmas cards Granger-cause Christmas, but they certainly don't cause Christmas!

Best wishes for the holiday season.

  1. Do sales of Christmas cards help forecast the occurrence of Christmas given information on past occurrences of Christmas? I don't think so! :)
