Powershell Script to get the tenancy end date given tenancy start date

on
Today I created a powershell script to generate the tenancy agreement end date given the start date.

function Get-BPTenancyDate($var_dateTenancyStarts,$var_TenancyYears)
{
    #Gets the tenance agreement end date
     Write-Host "Tenancy Duration for $var_TenancyYears years from this date   $var_dateTenancyStarts :"( [datetime]::Parse($var_dateTenancyStarts)).AddYears($var_TenancyYears).adddays(-1) -BackgroundColor Green
}

Get-BPTenancyDate -var_dateTenancyStarts "01/07/2008" -var_TenancyYears 2
