Day 355 – Calendar Question


I visited my friend David Wagner today, and we drove all around the Huron/Sandusky/Port Clinton area this afternoon. David just got home for Christmas from his teaching position on Bordeaux, France. I haven’t seen him since the beginning of September, so it was wonderful to spend all afternoon and evening with him. If everything goes according to plan, I am going to fly to France to visit him (and take photos!) over spring break at the end of March.

Anyway, after reading the Blue Eyes logic puzzle question, he posed a calendar question to me. He is fascinated with the intricacies of calendars, so this is a question he has already solved and he wants to see if I can figure it out. If you figure it out, please don’t post the answer in the comments. I want to figure it out. I just wanted to post it so other people can work on it, too. Here it is:

In our lifetime, every 28 years there is a year with two 31-day months each having a Friday the 13th. Find the next year when all of this will occur and list all months in that year with a Friday the 13th.

Good luck!
