How Many Biweekly Pay Periods Are in a Year?
A biweekly payroll normally has 26 pay periods, with 27 in some years. Learn why the extra payday occurs and how to plan for it.

A biweekly payroll usually has 26 pay periods because employees are paid once every 14 days. Some calendar years contain 27 paydays, depending on the weekday and date of the first payday.
Why 26 Is Normal
Twenty-six biweekly periods cover 364 days:
26 × 14 = 364
A common year has one day left over, and a leap year has two. Those leftover days shift the payday date slightly from one year to the next.
How a 27th Payday Happens
If the first scheduled payday falls early enough in January, repeatedly adding 14 days can place a 27th payday before December 31. Leap years make the alignment somewhat more likely because the calendar contains an additional day.
The event is about payday dates, not 27 complete 14-day periods fitting inside one year. Twenty-seven full periods would require 378 days. The first period may have begun in the prior year, or the last may end in the next year.
Pay Periods vs Paychecks
A pay period is the span during which work is recorded. A payday is when wages are issued. Organizations sometimes use the terms loosely, but their boundaries can differ because payroll processing happens after a period closes.
When checking for 27 paychecks, start with the actual first payday and add 14 days until the next date would fall outside the year.
Budgeting for a 27-Paycheck Year
Salaried employers using a fixed annual salary need a documented policy. Some divide the annual amount by 27 for that year; others keep the normal per-paycheck amount under their payroll arrangement. Employees should check the published pay calendar rather than assume the “extra” check is a bonus.
Benefit deductions may also be taken 26 times, 27 times, or skipped on selected checks. The payroll policy controls the result.
Biweekly Is Not Semimonthly
Biweekly means every 14 days and normally produces 26 checks. Semimonthly means twice per month and always produces 24 checks. The distinction affects monthly budgeting because biweekly payday dates move through the month.
Quick Answer
Expect 26 biweekly paydays in most years and 27 in occasional years. Use the employer's official calendar to confirm the exact count and deduction schedule.
