Never have, it would never occur to me to doubt that I already know. My assumption is that if you’ve ever needed to, you always will. I’m that way with the alphabet or months, I need to whisper the entire alphabet to myself to figure out which letter comes after q, same idea to figure out whether august is the 7th or 8th or 9th month. I assume we probably all have mental blind spots of one kind of another.
Edit: unrelated, but did you know that September, October, November and December are so named because they were originally the 7th, 8th, 9th and 10th months? Would’ve really helped me out if we stuck to that calendar…
