1. What Are Working Days?

Working days typically refer to Monday through Friday, excluding weekends (Saturday and Sunday) and public holidays. This calculator helps you count the number of working days between two dates while accounting for holidays.

2. How Does the Calculator Work?

The calculator uses the following logic:

Where:

• Mon-Fri — All weekdays between the start and end dates (inclusive)
• Holidays — User-specified dates to exclude from the count

Explanation: The calculator iterates through each day between the start and end dates, counting only weekdays that aren't in the holiday list.

3. Importance of Working Days Calculation

Details: Calculating working days is essential for project planning, business operations, contract deadlines, payroll processing, and service level agreements.

4. Using the Calculator

Tips: Enter the start and end dates (end date must be equal to or after start date). Optionally specify holidays as comma-separated dates in YYYY-MM-DD format.
