Commonly, a year consists of around 261 working days. This figure is derived from formulas used by the United States Bureau of Personnel Management to determine salaries.
The Bureau states that full-time pay rates are based on 2,087 annual working hours, which, when divided by the average number of 8-hour workdays, results in 261 workdays. However, this number might change dependent on factors including the company’s policy and the employee’s length of service, both of which can affect the amount of vacation and holiday time an employee receives.
