1. What is the NETWORKDAYS Formula?

The NETWORKDAYS formula calculates the number of working days between two dates, excluding weekends and optionally holidays. It's commonly used in business, project management, and financial calculations.

2. How Does the Calculator Work?

The calculator uses the NETWORKDAYS principle:

Where:

• \( \text{Start} \) — The start date
• \( \text{End} \) — The end date
• \( \text{Days} \) — Number of business days between dates

Explanation: The calculation excludes weekends (Saturday and Sunday) by default. A more advanced version could also exclude specified holidays.

3. Importance of Business Days Calculation

Details: Accurate business days calculation is crucial for project planning, SLA compliance, financial calculations (like interest accrual), and delivery time estimations.

4. Using the Calculator

Tips: Enter valid start and end dates. The calculator will show both total calendar days and business days (excluding weekends).
