    Hi Georges,

    Unfortunately, it is not possible, the birth date picker has a fixed drop down selections and do not identify existing duration of months and years. This will depend on how accurate the users will input data on it. 

    Thank you for your understanding.

    hi everyone !

    i saw a similar query this month and JotForm Support NicholasWestley gave this update on the fix:

    Hi, this has now been fixed.  If invalid dates are chosen in the birthdate picker an error will be shown.

    hope this helps.
