Need help from hacker who knows neopets?

This may sound dumb, I know the site has gone to heck and isn't worth playing anymore. I haven't been on neopets in 3 years. I have all of my account names and passwords recorded, but now they ask for a birthdate as well to enter the site. I don't remember the random dates I used on each account. So, I can't get on my accounts. I know they have a login page that doesn't ask for birthdate, but I don't know how to bring it up. I don't have anything worth stealing on my accounts, I sent everything to my main account, which I CAN access. If you think I want to hack an account for the stuff, you can go on the accounts you can play on the accounts yourself and see there is nothing.
