Author: Alice Gilman. A calendar year and an employer's pay periods do not always coincide precisely. Approximately every 11 years, an employer that pays employees on a biweekly basis will have an extra pay period. An employer that pays employees on a weekly basis will have an extra pay period every five or six years.
A semi-monthly payroll occurs twice per month, such on the 15th and last day of the month. Both payrolls have their advantages. Normally, a year has 365 days; however, a leap year has 366 days. A biweekly payroll has 14 days and 26 pay periods, which amounts to 364 days. Over time, this difference of one day during regular years and two days during leap years results in a 27th paycheck for biweekly workers. A semi-monthly payroll always has 24 pay periods, which results in less time and money spent on running payrolls.
