In general, I think a list of dates (either DDMMYYYY or YYYYMMDD) could
be useful.
If you know how old the users are and/or when those passwords have been
created, you'd also know which years to put on top of the list.
Because instead of DDMMYYYY users might prefer MMDDYYYY, this list
should also contain those dates first where DD is also a valid month.
And because users might use 1-9 instead of 01-09 (so you would have to
check both versions for these dates), I would start the list with those
dates where both DD and MM are in the range of 10-12.
This allows to apply a larger number of complex rules on the top n
entries of your dates wordlist even for very slow hashes where you can't
afford to try all these rules on the complete list.
Instead of all rules, just pick those rules that worked best on your
small subset, and try them on the remaining lines of your word list.

I wouldn't waste programming effort on this.
