When you need a working-days calculator
- Project deadlines: contracts say "30 working days" — figure out the actual calendar deadline.
- HR / payroll: count workdays in a month to compute daily-rate salaries.
- SLA / response times: "respond within 5 business days from receipt".
- Logistics / shipping: ETAs like "3-5 business days".
- Tax filings: deadlines are usually counted in working days.

Tips
- Government Saturday: enable "Exclude Saturday" for government work (Mon-Fri only).
- Add N days: use the "Add X working days" feature to compute future deadlines. Negative numbers walk backwards.
- Holidays on weekends: counted correctly — they don't double-bump the next workday.
