Business Days Calculator — How It Works

Operation: The calculator iterates through each day between the start and end dates, checking whether it falls on an excluded weekday (Saturday/Sunday) or a user-specified holiday. The result shows total calendar days, weekend days, holidays excluded, and the final working days count. All calculations run client-side with no server interaction.

  • HR professionals: Determine exact working days for payroll calculations, leave accrual, and attendance tracking.
  • Contractors: Compute billable working days for project proposals and invoicing.
  • Event planners: Count working days available before an event to build schedules.

Frequently Asked Questions

Why does this matter for project deadlines?

When stakeholders say "2 weeks," they often mean 10 working days, not 14 calendar days. This calculator provides clarity by excluding weekends and holidays upfront.

How do I add my country's public holidays?

Enter each holiday in the text area using the YYYY-MM-DD format (e.g., 2026-01-01 for New Year's Day). The tool will automatically exclude them from the working day count.
