In our parish, we keep our Crib and some of the decorations up until the Feast of the Presentation of the Lord, Candlemas on 2 February. We thus follow the medieval custom, not the Victorian custom of twelve nights and definitely not the modern secular custom of a Boxing Day clear out. Christmas in mediaeval England was probably a lot of fun and we need cheering up right now – so keep the decorations up!
