The date format for $bd is unclear.

Every example used is 12/12/year, so I can't tell: Is it using DD/MM/YYYY or MM/DD/YYYY?

The date from nwiz is used in the wordlist as-is, so the date format doesn't actually matter to the program. It is treated like all the other strings. Use the format most likely used by the person you're targeting. This is also why the year is asked again separately.
