It leads to 318. There is no 340 day, no 360 or 361 or 383 day, only 4/26 day, and 440+6 is not in the cards. We dont even get a 392 day. We do get a 4/08 and 4/16. And 400? There is no April pre-fool's day. You're outta luck.
I'm sure that if you want to go metric with all the rainbows and unicorn farts the unfortunate sizes can get a day.
Honestly, if you need to go metric, I suspect that you have a little sugar in your tank, and you probably need a wrist brace.
