In Chapter 15, he wrote that November was 'Blod-monath' and December, as well as January, was 'Guili' (the g is pronounced as a 'y'). He also mentioned that the night of Christmas, December 25th, was called Modranicht, or 'Mother's Night', Bede suspected it was called this due to some ceremonies on that night. It was also the beginning of the new year. It is a shame he did not say more about these winter celebrations. We can only speculate what went on.
