1. What is Business Days Calculation?

Business days calculation determines the number of working days between two dates, excluding weekends and specified holidays. This is essential for project planning, deadline tracking, and business operations.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Business\ Days = Total\ Days - Weekends - Holidays \]

Where:

\( Total\ Days \) — Total calendar days between start and end dates (inclusive)
\( Weekends \) — Number of Saturdays and Sundays in the period
\( Holidays \) — Number of specified holidays that fall on weekdays
