The system of payroll accounting may provide for the fixing of staggered or cycled payroll periods or pay dates by designation of the days of the month or week on which certain employees’ payroll periods shall be fixed and by designation of the date of payment for the earnings during a designated payroll period. Such established pay dates, as far as practicable, shall be uniform for all employees of each state agency employed in the same geographical area, and if biweekly payroll periods are established under Kan. Stat. Ann. § 75-5501a, such established pay dates shall not be more than fourteen (14) calendar days following the close of the payroll period. For the purpose of implementing this section, the director of accounts and reports may alter any established payroll period or pay date by not more than seven calendar days by establishing a schedule of staggered payroll periods and pay dates as provided in this section.
