Business days from date calculator
Add or subtract business days from any date. Find the date 5, 10, 30, 60, or 90 working days from today. Free workday calculator.
How this business day calculator works
Enter a start date and a number of business days, then choose whether to add or subtract them. The tool steps one day at a time and counts only Monday to Friday, skipping Saturdays and Sundays, until it has counted your number. The start date itself is not counted: adding 1 business day to a Friday gives the following Monday.
It does not remove public holidays, because they differ by country, region and employer. If a holiday falls on a weekday in your range, add one more business day for each.
Examples
| Start | Operation | Result |
|---|---|---|
| Monday, October 19, 2026 | Add 30 business days | Monday, November 30, 2026 |
| Friday, October 23, 2026 | Add 5 business days | Friday, October 30, 2026 |
| Monday, November 2, 2026 | Subtract 10 business days | Monday, October 19, 2026 |
Thirty business days is exactly six weeks, which is why the first example lands on the same weekday.
Where business days are used
- Contracts and notices: a clause such as “within 30 business days”.
- Delivery and refunds: couriers and banks often quote business days.
- Project plans: turn a number of working days into a delivery date.
To count the working days between two dates, use the business days calculator. For a deadline you want in view, add the result to Left as an Ahead countdown.
