Business Days Calculator
Count weekdays (excluding weekends) between two dates, or add business days to a date.
Weekend days don't count toward most shipping estimates, project deadlines, or legal notice periods — this counts only Monday through Friday between two dates.
What this doesn't account for
This counts weekdays only — it doesn't exclude public holidays, since holiday calendars vary by country. If your deadline needs to account for specific holidays, subtract those days manually.
Frequently asked questions
Why is business day count different from total days?
Every 7-day week contains only 5 business days, so the gap grows the longer the span.
Does this work across a year boundary?
Yes — the calculation handles year boundaries, leap years, and varying month lengths correctly.
