An Advent calendar is normally a countdown to Christmas, with a treat for every day. Matt Shirley took that idea and filled in the last couple of weeks before Christmas. Sorry, no chocolates here. Whether any of the blocks in this Advent calendar apply to you or not, you get the idea that it may have been compiled from personal experience. It could have been his or someone else's- I'm not judging.
If there are any blocks that don't apply to your family, hooray! You're ahead of the game. I spent decades celebrating Christmas by working while my family went to Florida, and even for a few years after I had my own family- and so that involved supervising the preparation of Christmas dinner by phone. Now I am planted at home, and have to assure any relatives that can't make it that I completely understand. I am well-versed in workarounds.
