NSCalendarDate also includes time, so unless the NSDate that is
preexisting is in the same time-zone, and has the same time specified
as is provided by NSCalendarDate when no time is in the string, that's
not going to work reliably.
One solution might be to convert the string to a sortable format of a
date (YYYY-MM-DD), and then have a category on NSDate return a string
formatted similarly, and then you could sort/compare those with the
usual string beasties.
