How to use it
Pick the two dates. A notice period, a project window, a delivery promise — in either order.
Choose inclusive or not. Tick the box if both the first and last day should count.
Read the working days. Monday–Friday only, with the raw calendar-day count beside it for reference.
Where business days actually matter
Notice periods, SLA clocks, invoice terms ("net 30" is calendar days; "10 business days" is not), sprint planning and delivery promises all run on working days — and hand-counting them across month-ends and weekends is where mistakes creep in. This calculator walks the real calendar day by day, skipping Saturdays and Sundays, so the number you quote is the number that is true. The honest limit: public holidays are yours to subtract, because they differ by country and employer.
