    Hi @paolamzavarce, 

    "Generate Attribute" operator is your best friend :) You can use date_diff() function in the formula to calculate the gap between the birthday and Aug 8 1990. Just make sure date_diff is applied to two dates. And it will return the time difference in milliseconds. You can convert into years by rescaling.

    Cheers,
    YY
