Well I`ll admit, I never looked it up on line, but have always trusted my Housekeeper/Caregiver`s ongoing knowledge about such things for over a decade or so, and I called my childhood friend yesterday to see how he and his family were doing, and brought up NCB Day, and he also confirmed the 9/18 date that he and his wife partook the consumption of said theme based meal in celebration, and they don`t usually eat hamburgers of any style.
FWIW, I have come to understand that there are various sources claiming various days on the internet for various food theme based celebration days for all types of food.
So, who`s to say what source is claimed to be truly pre-internet "official" these days concerning such things !
No worries, usedto
