Please read the section "Relative items in date strings" in the coreutils
manual:

       The fuzz in units can cause problems with relative items.  For
    example, `2003-07-31 -1 month' might evaluate to 2003-07-01, because
    2003-06-31 is an invalid date.  To determine the previous month more
    reliably, you can ask for the month before the 15th of the current
    month.  For example:

         $ date -R
         Thu, 31 Jul 2003 13:02:39 -0700
         $ date --date='-1 month' +'Last month was %B?'
         Last month was July?
         $ date --date="$(date +%Y-%m-15) -1 month" +'Last month was %B!'
         Last month was June!

Andreas.
