Have a Merry Christmas everyone!
Given my slight obsession with maps here is Map of Christmas Dinner Across the World:
For some holiday enlightenment I suggest checking out this fascinating article on the economic history of Christmas from Marginal Revolution. Here is the first paragraph:
While “Christmas” is new, the notion of a consumption splurge after the fall harvest, followed by a lean late winter-early spring season (Lent/Ramadan) before the spring harvest is deeply rooted in pre-modern agricultural reality. When you have an abundance of perishable goods it makes sense to consume them before they go bad, and then to string out the more limited supply of durable foodstuffs when fresh foodstuffs are scarce. In the same way, summer vacation is rooted in the need to free up children for agricultural labor at times of peak demand. As noted above, spring weddings supply a consumption boost after the Spring Harvest and also are timed to minimize the likelihood of critical parts of a first pregnancy taking place during the lean late winter-early spring (although these days it has more to do with the end of the school year).
