How Working Days Between Dates Are Determined
Measuring the duration of business operations requires filtering out non-operational calendar time. In standard US business environments, a regular full-time workweek consists of five consecutive 8-hour working days (Monday through Friday), yielding 40 weekly hours. Saturdays and Sundays are excluded as statutory rest days.
The 5/7 Workday Ratio & Estimation
Over long intervals, roughly 71.4% (5/7) of calendar days are standard business days. However, exact payroll and project deadlines cannot rely on averages because statutory holidays and uneven month boundaries shift working day distributions by up to 3 days per month.
Statutory Federal Holidays Deductions
Under 5 U.S.C. 6103, there are 11 permanent federal holidays each calendar year. When accounting for business days in commercial agreements, financial settlements, and court filings, statutory holidays are treated as non-working days.
