I honestly I don't think there SHOULD be a reason to be scared of a literal number. It doesn't make very much sense. I personally agree with the user ¨felineactivist¨ in the comment section of this article about this. :/

I believe this fear is irrational. However, I'm not about to make fun of anyone who's scared of this day and I encourage them to get over this fear and prosper on these days.
