If you ever asked yourself why we celebrate Christmas in December (and some in January), I am suggesting that you take a strong cinnamon tea with lemon or orange flavour, get an armchair and read this wise article from Andrew McGowan. It is quite inspiring and has a lot of interesting facts from the past: http://www.biblicalarchaeology.org/daily/biblical-topics/new-testament/how-december-25-became-christmas.
