The Annual Breakdown
A standard calendar year contains 365 days, which equals 52 weeks plus 1 extra day (or 2 extra days in a leap year). 52 weeks contain 104 weekend days (52 Saturdays and 52 Sundays).
Net Working Days
Subtracting 104 weekend days leaves 260 or 261 potential working weekdays. Deducting the standard 10–11 federal or statutory public holidays results in approximately 250 to 251 net working days per year.
Annual Work Hours Calculation
Multiplying 260 weekdays by an 8-hour workday yields 2,080 annual work hours (the benchmark figure used in corporate budgeting and payroll formulas).
