Calculating Employee Tenure

I have a report that displays each company employee and their tenure based on a hire date. I'd like to amend my formula to show the tenure calculated as of Dec 31st of the prior year versus it being calculated up to the current day of the year. 

Current Formula: 

var number Years = Floor(ToDays(Today() - [Original Date of Assignment])/365);
var number Remainder =Rem(ToDays(Today() - [Original Date of Assignment]),365);
var number Months = Floor($Remainder/30.44);
var number CalcDays = Ceil(Rem($Remainder,30.44));
If([Active],

ToText($Years) & " Years" & " " & $Months & " Months" & " " & $CalcDays & " Days",
If([Role] = "Private Market Agent", "PMA", ""))

The "Tenure" displays as such in their record: 


Thanks for any help with this!
