Countdown to a given birthday

[Agentshevy]

I have really tried to figure out this calculation by subtracting the birthday from the current date, I guess that didn't work. I just need to have a countdown to a contacts birthday.

Please how do I go about this?

How about =

Let ( [
today = Get ( CurrentDate ) ;
birthday =  Date ( Month ( Birthdate ) ; Day ( Birthdate) ; Year ( today ) ) ;
upcomingBirthday = Date ( Month ( Birthdate ) ; Day ( Birthdate) ; Year ( today ) + ( today ≥ birthday ) ) 
] ; 
upcomingBirthday - today
) 

Result is Number and the calculation must be unstored.
