I was taught about Roman numerals in school (mid-90s) but it was a brief thing, maybe a few homework assignments in a larger unit about Roman history. Certainly not hours of drilling. I can read a clock fine, and I can read a date if I spend some time thinking it through. But it's not really a life skill.

Not remembering the details, but learning it in the 70s or so, I can look at a Roman date and not immediately grasp the year in terms I'm more familiar with but I can decode it in 10 seconds or so. I assume there was a fair bit of drilling if I remember after all this time. But then I had a couple years of Latin too.
