Ignore DOB when searching for a date

I suspect this can't be done but thought it worth asking!!
I use Hazel to sort all letters/documents that come to the house after I've scanned them. Every Hazel rule first searches for the first instance of a date (which is usually the document date) and I incorporate this date into a new file name to keep all files in date order.
The problem I have, particularly with documents relating to medical stuff, is that the first date is sometimes my DOB. Is there a way to ask Hazel to ignore certain dates when searching for dates?
Thanks for any advice/help
