A good UI implementation could at least check the pattern against
every day currently displayed in the date-picker and gray out any that
don't match it.  I don't know how feasible it would be to gray out the
next/previous month buttons or anything just based on patterns,
though.  Also, I'm not sure we really want to force people to use
regex for this . . .

That might be possible with regex in theory, but I really don't want
to see it.  :)
