OK this is why they need #autistic people to watch shows before they put them out. Not just for continuity, but for checking actual facts.

I am finally watching the Queen's Gambit, which of course I love for many reasons, not just redheads and chess, but she just came home from Paris and there's a August 1967 calendar on the wall next to the phone -- and it is utterly wrong!

It shows the month starting on a Sunday. The first day was a Tuesday!
