The annual average number of workdays is approximately 261. This value is derived from the computations performed by the United States Bureau of Personnel Management to determine pay rates.
According to the Bureau, full-time pay rates are based on 2,087 working hours a year. Dividing this number by the average number of 8 hours in a workday gets 261 workdays. Due to the fact that variables like as vacation and holiday time are provided at the discretion of individual employers, this figure can fluctuate dependent on company rules and years of service.
