No; this isn't crazy, but it's usually a bad idea.

Regardless of whether you actually have a day variable -- you could
fudge that by using 1 or 15  instead -- you will end with daily dates
and lots of gaps. That's awkward for almost everything that might
follow.

If you have monthly dates, you want monthly dates and should use -ym()-.
