Example of Using the Business Day Calculator

Suppose you have a project starting on January 10, 2026, and you want to add 10 business days. Additionally, your company observes January 15, 2026 as a holiday.

Step 1: Start Date = 2026-01-10
Step 2: Business Days to Add = 10
Step 3: Holidays = 2026-01-15

The calculator will process the days as follows:

  • January 10: Start
  • Skip weekends (January 11–12)
  • Skip holiday (January 15)
  • Add 10 valid business days

Result: The end date will be January 25, 2026, with 4 weekends skipped and 1 holiday skipped.

This ensures you never miscalculate deadlines and plan projects or tasks efficiently.
