The most famous is probably friday the thirteenth, but setting that aside, what other days in general (regardless of specific date) do you hold some superstitions about?
I never could get the hang of Thursdays
Don’t touch production on Friday afternoon.
Kevin will ask for a change to production on Friday afternoon.
I’m not superstitious. It’s bad luck.
Only car accident I’ve been in was on Friday 13th. It was minor damage and I don’t think it’s reason to be superstitious.
I never push updates on a Friday because I don’t want to work weekends if something goes wrong.
