Biweekly vs. Semimonthly Pay Schedules
Understand 26-paycheck and 24-paycheck schedules, why paydays move, and how to plan a shift calendar around each one.
Matthew NewmanAuthor and editorial reviewer · Primary sources checked 2026-08-28Biweekly and semimonthly sound similar because both usually produce two paydays in most months. The difference becomes obvious when you follow the calendar for a full year.
Your employer’s payroll calendar is always the source of truth. Use the schedule type as a planning model, then confirm cutoffs and paydays against official records.
Biweekly follows a 14-day rhythm
A biweekly schedule repeats on the same weekday every two weeks. Because a year contains more than 52 exact weeks, two months often contain a third payday.
The pay period and payday are not necessarily the same dates. Employers need processing time, so learn both the period end date and the deposit date.
Semimonthly follows the calendar
A semimonthly schedule usually pays on two named dates, such as the 15th and last day of the month. Weekend and holiday rules can move the actual deposit date.
Each semimonthly period can contain a different number of weekdays. For hourly work, that makes it especially important to confirm how the employer groups shifts.
Plan with official cutoffs
Save the exact payroll calendar when your employer publishes it. Then place shifts inside the correct pay period and avoid assuming that every shift worked before payday belongs to that check.
If a shift crosses midnight or a payroll cutoff, follow the employer’s rule rather than splitting it based on intuition.
