Description

According to Wikipedia at least, it's valid to specify a month only, without a specific day, ie YYYY-MM only. I have an API I'm working with that returns months in this format.

Sadly this throws a parser error: [{ col = 8, problem = ExpectingSymbol "-", row = 1 }].

I can work around it of course by just tacking -01 onto the month, and maybe this is even the correct way you'd translate that format to a Posix date anyway, but I thought I'd point it out.

Contributor guide

Research direction
Modify the ISO 8601 parser to accept month only dates (YYYY MM). The parser currently expects YYYY MM DD. Add optional day component handling.
