The count is inclusive of both the start and end date, which matches how contracts and shipping estimates read "5 business days". Because the weekend is different around the world, you pick the convention that fits: Saturday and Sunday, Friday and Saturday, a single rest day, or none. Everything is computed locally in your browser - no dates are uploaded and no account is needed.

What is a business days calculator?
A business days calculator counts the working days between two dates, excluding weekends and any holidays you list. It answers deadline questions like "how many working days until this date" by ignoring Saturdays and Sundays (or whichever weekend you choose) so you get a realistic count.
How to use
- 1Pick your dates. Choose a start date and an end date. If you enter them backwards, the tool swaps them and still counts correctly.
- 2Set the weekend. Select which days are your weekend - Saturday and Sunday by default, or another convention.
- 3Add holidays (optional). Paste any public holidays, one per line, and they are removed from the count if they fall on a working day.
- 4Read the result. The business-day count updates instantly, along with calendar days, weekend days, and holidays excluded.
Who it's for
- Project managers setting realistic deadlines that skip weekends and company holidays.
- HR and payroll teams counting working days for notice periods, leave, or probation windows.
- Freelancers and agencies quoting turnaround times like "10 business days" with confidence.
- Shippers and buyers estimating delivery when a carrier promises a number of working days.
FAQ
Are the start and end dates both counted?
Yes. The count is inclusive of both endpoints, so Monday to Friday of the same week is 5 business days. This matches how legal and shipping timelines usually read a span of working days.
Does it skip public holidays?
Only the holidays you enter. There is no built-in national calendar because holidays differ by country and region, so you paste the dates that apply to you, one per line, and the tool removes any that land on a working weekday.
Can I change which days are the weekend?
Yes. You can set the weekend to Saturday and Sunday, Friday and Saturday, Sunday only, Friday only, or none at all, so the count fits your local working week rather than assuming Monday to Friday.
Is my data uploaded?
No. Every calculation runs locally in your browser. The dates and holidays you enter never leave your device and nothing is sent to a server.
Is the business days calculator free?
Yes, it is completely free with no sign-up, no limits, and no download. It works instantly in your browser on desktop and mobile.
What happens if my end date is before my start date?
The tool swaps the two dates, counts the working days between them, and shows a small note that the dates were swapped, so you still get a correct, non-negative business-day count.
