A semi-monthly paycheck schedule means employees are paid twice a month—usually on fixed dates like the 15th and the last day of the month (24 pay periods per year). To make it easy to use, choose consistent pay dates, clearly define each pay period (for example, the 1st–15th and 16th–end of month), and adjust paydays that fall on weekends or holidays to the prior business day. Share a full annual payroll calendar with pay period dates, payroll submission deadlines, and payday dates so employees can plan bills and budgeting. Using payroll software or a shared digital calendar also helps reduce confusion and missed deadlines.
