About the Business Days Calculator

Business Days Calculator iterates date-only UTC values, excludes Saturdays and Sundays and removes unique holiday dates supplied by the user. It does not assume a country calendar.

How to use the Business Days Calculator

  1. Enter the date range.
  2. Add any applicable holidays in ISO date format.
  3. Choose endpoint handling and count the remaining weekdays.

Practical tips

  • Regional weekends can differ; this version uses Saturday and Sunday.
  • List observed holiday dates rather than only their nominal dates.
