calculation of hourly rate of pay
Until 1984, an hourly rate of basic pay was computed by dividing the employee's annual rate of basic pay by 2,080 hours (the number of hours in 52 workweeks of 40 hours) and rounding to the nearest cent. For a regular full-time employee, the hourly rate was then multiplied by 80 to determine the biweekly gross pay. This formula presumes a calendar year consisting of exactly 52 weeks or 364 days. However, a calendar year actually consists of either 365 or 366 days.
