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.
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.
I never had a thing about Friday the 13th until I broke my ankle off on Friday the 13th in 2018. Not that I’m superstitious, it just got stuck in there and now I get a little heebie jeebie thinking about it cause I’m scared it will happen to my right ankle next.
For a long time I felt that caffeine just didn’t work the same for me on Fridays, and actually made me sleepier on those days.
