Business days typically refer to Monday through Friday, excluding weekends (Saturday and Sunday) and public holidays. They are commonly used in business, legal, and financial contexts to calculate deadlines, delivery times, and service level agreements.

The calculator counts all weekdays (Monday to Friday) between two dates, excluding any specified holidays:

Where:

• Weekdays — Monday (1) through Friday (5)
• Holidays — User-specified dates to exclude

Explanation: The calculation starts from the start date (inclusive) to the end date (inclusive), counting only days that fall on weekdays and aren't listed as holidays.

3. Importance of Business Days Calculation

Details: Accurate business day calculation is crucial for contract fulfillment, project planning, financial settlements, and legal deadlines where weekends and holidays shouldn't be counted.

Q4: What about time zones?
