superstitious

First to admit I am a superstitious soul.
I got a super book for Christmas "'The Penguin Guide to the Superstitions of Britain and Ireland' with which I can wind myself up even more !!
At this time of year the question is . .  what day is Twelfth Night ??
There are conflicting answers - 5th or 6th Jan.
I say 6th - so decorations stay up until then - all down on 7th !! (fingers crossed)
