How Many Biweekly Pay Periods Were in 2024?

A calendar year has 365 days (or 366 in a leap year). Dividing 365 days by 14 days per pay period gives 26.07 pay periods — which rounds to 26 full pay periods in most years. In 2024, which was a leap year with 366 days, employees whose pay cycle began on January 1 or January 2 received 27 paychecks rather than 26, because the extra day caused the cycle count to roll over to 27.

Whether your 2024 included 26 or 27 pay periods depends entirely on when your employer's pay cycle started and which day of the week you were paid. Understanding how biweekly pay works helps clarify why the count changes between years. Each pay period corresponds to specific business days, so knowing when a pay period begins and ends is essential for timing direct deposits and bill payments correctly.

A 27-pay-period year gives you one extra paycheck compared to the typical 26. If you are paid a fixed annual salary, each of the 27 paychecks is slightly smaller because your annual salary is divided by 27 rather than 26. This reduces each paycheck by approximately 3.7% for that year.

For hourly employees, a 27th pay period means an extra two weeks of wages — a meaningful income boost. For salaried employees, the per-paycheck reduction may affect auto-pay bills, savings contributions, or budget allocations tied to paycheck amount. Reviewing recurring automatic payments at the start of any 27-period year is a practical precaution. To correctly set your withholding for changes in pay frequency, update your W-4 form accordingly. This is also a good moment to review your broader budget — understanding how equal billing works can help stabilize monthly expenses even when your per-paycheck amount fluctuates.

Biweekly and semimonthly pay schedules are often confused but are not the same. A biweekly schedule pays every two weeks (26 times per year). A semimonthly schedule pays twice per month on fixed dates — such as the 1st and 15th — resulting in exactly 24 paychecks per year regardless of the calendar.

The biweekly schedule is the most common pay frequency in the U.S., used by approximately 43% of employers according to Bureau of Labor Statistics data. The difference matters for monthly bill planning: semimonthly employees always receive exactly 2 paychecks per calendar month, while biweekly employees receive 3 paychecks in two months of the year.

Your employer uses the number of pay periods in the year to calculate how much federal income tax to withhold from each paycheck. This calculation is based on IRS Publication 15 withholding tables, which account for the annualized income implied by each paycheck amount.

In a 27-pay-period year, a salaried employee's per-paycheck gross is lower, which may cause slightly less withholding per check. Your total annual withholding should still be accurate if your W-4 is properly completed. Use the IRS Tax Withholding Estimator at irs.gov to verify your withholding whenever your pay frequency or amount changes. For hourly workers, understanding daily earnings targets within each pay period helps set realistic income expectations across a 26- or 27-period year.

Use this table to reference the number of biweekly pay periods for recent years. The exact count for your situation depends on when your employer's payroll cycle begins relative to January 1.
