Tips & Best Practices

  • This tool counts weekdays only — Saturday and Sunday are excluded. Country-specific public holidays are not subtracted; use it as a quick baseline.
  • For finance / payroll where holidays matter, cross-reference against your local holiday calendar after running the count.
  • The Include End Date toggle flips between "days between" (exclusive) and "days from start through end inclusive".
  • Reverse calculation (start + N business days = end) is useful for SLA / due-date arithmetic.
  • Everything is computed locally.
