Theres a much simpler way to white or blacklist dates, using a Predicate<Date>. The Predicate can then have any logic it wishes to allow or disallow any date based on any logic be it only allowing Mondays, only allowing the first of each month or whatever. Its not practical to require a List of ALL valid or ALL invalid, there could be 100s or 1000s or a lot more than that.
