Analysis of information sources in references of the Wikipedia article "Epiphany (holiday)" in English language version.
According to the tradition of the 12 days of Christmas (explained above), January 6 is the earliest you should be taking down your Christmas tree. According to the legend, bad luck will befall those who stop the Christmas cheer any earlier.
Any Christmas decorations not taken down by Twelfth Night (January 5th) should be left up until Candlemas Day and then taken down.
In the secondary arrangement of Mark which is found in the non-B manuscripts, the Roman Year was followed. This arrangement would be the most natural way of explaining the origin of January 6 as a festival of the Baptism of Jesus.
We prefer, like good Anglicans, to go with the logic of the liturgy and regard January 5th as the Twelfth Day of Christmas and the night that ends that day as Twelfth Night. That does make Twelfth Night the Eve of the Epiphany, which means that, liturgically, a new feast has already begun.
Twelfth Night 2017 is on Thursday 5 January, which is when we're meant to put away our Christmas decorations or there'll be bad luck in the year ahead. If you miss the date, some believe it's necessary to keep decorations up until Candlemas on 2 February – or you'll definitely have a rubbish year.
The birth of Christ, the story of the Magi, Christ's baptism, His divine manifestation, miracle at Cana, and the feeding of the crowds formed the festival of Epiphany on January 6 as indicated in earlier Alexandrian and Syrian traditions.
The current pattern in the Anglican Church is to have an extended Epiphany season (called Epiphanytide). This is why Nativity scenes are sometimes kept in churches throughout January. Epiphanytide: Rather confusingly, however, the other two main 'manifestations' marked in Epiphanytide concern Jesus as an adult: his baptism in the River Jordan, when the Holy Spirit descends on him in the form of a dove (on the Sunday after Epiphany), and his first sign: the turning of water into wine at the marriage feast in Cana in Galilee. This latter event – the third 'epiphany' of the season – is only to be found in John's gospel.
