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 bi-weekly (every other week) pay period results in 26 paychecks in a year. Some hourly employees are paid bi-weekly, and some salaried employees are too. A semi-monthly (twice a month) pay period results in 24 paychecks in a year. Usually, salaried employees are paid semi-monthly. A monthly pay period results in 12 paychecks in a year. Almost all monthly pay periods are for salaried employees.
