What is Date Modifier?
Differentiator that you use to determine different paydays for different employees for whom payroll is run with the same periodicity. Ex : Payroll is run monthly in your enterprise. The payday is the 15th of the month for industrial employees and the 25 th for salaried employees. Since the payroll periodicity (monthly) is the same for both groups of employees, the system requires two date modifiers as differentiators to be able to determine different paydays.
