Christmas Price Index, 2006-7Every year since 1984, PNC Wealth Management has calculated the cost of the gifts in the classic holiday song “The Twelve Days of Christmas.”
1. Total cost of items if one repeated
all earlier verses on each successive day: that is, 12 (1 x 12)
partridges in pear trees, 22 (2 x 11) calling birds, 30 (3 x 10) French
hens, and so on.
