Try this.  i suspect that Dan's formula will not work

This formula was for Age, but I changed it to be used for completed years of service.


var date EST = [Empl Svc Dt];

Year(Today())-Year($EST)
-
If(
Month(Today())<Month($EST)
or
(Month(Today())=Month($EST) and Day(Today())<Day($EST)),1,0)

    I am trying to do this however I don't need to know their actual years of service as today, only as of the date an incident was reported.  Basically I need to know the years between Hire Date and Date Reported.

    Try this
    var date HireDate = [My Hire Date field];
    var date IncidentDate = [My Incident Field];


    Year($IncidentDate -Year($HireDate)
    -
    If(
    Month($IncidentDateToday()) < Month($HireDate$EST)
    or
    (Month($IncidentDate) = Month($IncidentDate) and Day($HireDate <Day($IncidentDate),1,0)

    Corrected:
    var date HireDate = [My Hire Date field];
    var date IncidentDate = [My Incident Field];


    Year($IncidentDate -Year($HireDate)
    -
    If(
    Month($IncidentDate) < Month($HireDate)
    or
    (Month($IncidentDate) = Month($IncidentDate) and Day($HireDate <Day($IncidentDate),1,0)

    Worked with a slight adjustment:


    var date HireDate = [Employee Adjusted Service Date];

    var date IncidentDate = [Date Reported];

     

     

    Year($IncidentDate) -Year($HireDate)

    -

    If(Month($IncidentDate) < Month($HireDate)

    or


    Month($IncidentDate) = Month($IncidentDate) and Day($HireDate) <Day($IncidentDate),1,0)



    Thanks!

    I just noticed this is giving me a negative 1, I expected this for when the Date Reported was before the Employee Adjusted Service Date, however this is also happening in instances such as Date Reported = 5/23/17 and Employee Adjusted Hire Date = 1/15/2017

    You can put a floor of zero on the result.

    var date HireDate = [Employee Adjusted Service Date];

    var date IncidentDate = [Date Reported];

      

    var number RawCalc = Year($IncidentDate) -Year($HireDate)

    -

    If(Month($IncidentDate) < Month($HireDate)

    or


    Month($IncidentDate) = Month($IncidentDate) and Day($HireDate) <Day($IncidentDate),1,0);

    Max(0, $RawCalc)

    This field is currently Formula Numeric, I'd like to add that if [Employee Adjusted Service Date] is Null this field reflects as "Unknown".  I tried the following but it doesn't work.  Any suggestions?

    var date HireDate = [Employee Adjusted Service Date];

    var date IncidentDate = [Date Reported];

     

    var number RawCalc = Year($IncidentDate) -Year($HireDate)

     

    -

     

    If(IsNull([Employee Adjusted Service Date]), "Unknown",

    If(Month($IncidentDate) < Month($HireDate)

     

    or

     

    Month($IncidentDate) = Month($IncidentDate) and Day($HireDate) <Day($IncidentDate),1,0));

     

    Max(0, $RawCalc)
