im just a beginner, but i think you can use “seconds since 1970” block for each date… difference between those 2 will get you age in seconds… than get year, month, day from seconds … 🤔

You need to convert the text label to number by multiplying it by 1 or adding 0 to it and the comparison will yield correct results
