Terribly confusing to be reading along in Austen or Dickens or even Miss Read, and come into a passage describing something happening in Michaelmas Term.
Boxing Day is a little more familiar, but still kind of wispy or vague to most Americans.
Hence, some lists for quick reference. It may be helpful to others; certainly it will be for me.

St. Andrew’s Day, honoring the patron saint of Scotland is an official holiday in Scotland and is celebrated on November 30.
However, St. George’s Day (honoring the patron saint of England) is not an official bank holiday, but celebrated by patriotic English citizens. Wikipedia says: “The date of St George’s day changes when it is too close to Easter. According to the Church of England’s calendar, when St George’s Day falls between Palm Sunday and the Second Sunday of Easter inclusive, it is moved to the Monday after the Second Sunday of Easter.”
Information was gathered from the book “What Jane Austen At and Charles Dickens Knew” by Daniel Pool and this Wikipedia article on English Holidays.
