Oops, handle date parsing errors in Dyeworks logic

Huh, I thought I'd tried some invalid dates and they gave me
*surprising* output instead of raising an error. Well, maybe it can do
both, depending on exactly the nature of the unexpected input?

In any case, I found that a bad month name like "UwU" raised an error.
So, let's catch it if so!

 			# something surprising! But the heuristic nature helps with e.g.
 			# flexibility if they abbreviate months, so let's lean into `Date.parse`.
