My mom has been reading a lot of books recently and she asked me if I ever heard of Michaelmas. I did not she said it was in conjunction with Christmas. The sentence that she read in this particular book stated, " Well I shall say good night to you then, Thomas, and a Merry Christmas. I am convinced this shall be the finest Michaelmas of them all with you here."
She told me that there were a few other books that she read with this same reference to Michaelmas and Christmas.
I looked in Logos and it has Michaelmas is the feast of St. Michael (the archangel) on September 29. Is there more of a connection with Christmas and Michaelmas?
