Dr Mike Williams that today is Tjugondag jul in Sweden and Finland, a traditional twentieth night celebration when the festive tree is taken down and all the remaining food eaten. (I guess it all keeps well there where it's a bit nippy).
Apparently it is also the day when people dressed as goats visit houses and demand food and drink from the residents. In English, the day is St Cnut’s Day, after the Danish Viking King, and an old aphorism had it that evil Cnut took Christmas away at Tjugondag jul.
I think Cnut's Day needs considerably greater exposure in this country. What a great opportunity to dress up as a Womble from the dark side! Bring it on!
