It is generally twenty-six times a year. The time period determination is calculated as eighty hours per day for the employee.

This system is also preferred by the employees as it is easy for them to plan their budget. Since it is very finite and deciding dates are set and provided on a two-day trend per month.

The hourly processing is slightly complicated when compared to that of the bi-weekly system. The scale of pay is also considerably large in terms of a bi-monthly system of payment.
