Birthday countdown, X days!

So I just read that the new Prius will have their trim levels noted with Roman Numerals? That's silly. I really don't like Roman Numerals. They make my head hurt. Reading is hard enough. Roman Numerals is like reading AND calculating. Like seriously. What's the point. We have evolved a bit over the past few years and I feel like we could use actual numbers, not this weird letter/number shit. BUT then. I thought. I wonder what my birthday looks like in RN. I wonder what my birthyear would look like.
III XXI MCMLXXIII
See. I mean seriously.
So much easier to say
3.21.73
It's so cute. 3.21.73. Like a kitten.
