The Difference Between Calendar and Business Days
While Calendar Days represent every single day on the Gregorian calendar, Business Days (or Workdays) specifically count the days when commercial operations and legal deadlines are active. In the United States, this standard typically excludes Saturdays and Sundays.
Our tool is critical for Project Management and Legal Compliance because it accounts for the 2026 US Federal Holidays. Missing a filing deadline by miscounting a federal holiday can lead to significant fiscal penalties.
