Upgrading from 4.2.1 to 5.1.4.

When I want to change the Account when I press save, keep getting an error message birthdays. The birthday I have correctly set. What is the problem ???

Hello.

What I did and it worked is an upgrade from 4.2.2 to 5.1.0 and then 5.1.4 and now it's all ok.
With 5.1.3 does not work

Thanks
