How it's counted
Business days count Monday to Friday only. Starting tomorrow, the calculator skips each Saturday and Sunday until it has counted 40 working days. Public holidays are not skipped, so add one day for each holiday that falls in between.
In a spreadsheet
In Excel or Google Sheets, type =WORKDAY(TODAY(),40) and format the cell as a date. WORKDAY skips Saturdays and Sundays; add a holiday list as a third value to skip those too. To count from a different start date, use the date calculator.
