not an re expert, but grep solves this with -v flag (ie it looks for a match

[s for s in mylist if not r.match(s)]

where mylist contains a list of dates and you want to create a list
containing those not matching your re.

where xxx is your regular expression below, means: match anything (the .*)
but only if the lookahead does not match your re.
