foxy decoration, Epiphany, Twelfth Night

So... I have always thought that Twelfth Night was the same as Epiphany - that is, January 6th.  And that's the day (in my British traditional way) that I was brought up thinking that Christmas decorations are taken down.  But ... seemingly some people start counting nights on Christmas Day itself (which takes you to Jan 5th); some, the night after.  Logically, indeed, and counting on my fingers, Twelfth Night should be tonight.  But Foxy isn't coming off the mantelshelf till tomorrow; and the tree will come down then, too - though the farolitos may continue stretching down our garden path until Eldorado's prescribed day for the removal of lights, which is January 15th.
