To calculate age in Tableau, you need to use the date functions. So, for example, to solve this problem, we can use the DATEADD and DATEDIFF functions. The first function is used to add a certain number of days, months, etc., to the current date. The second function calculates the interval between two dates. This is a powerful combination of functions, and it will help calculate not only age but also any interval between two dates.
IF DATEADD('year', DATEDIFF('year', [Birthday], TODAY()), [Birthday])> TODAY()
THEN
DATEDIFF('year', [Birthday], TODAY())-1
ELSE
DATEDIFF('year', [Birthday], TODAY())
END
