Calculate a date N business days out or the number of business days, excluding weekends.

Category: Date & Time

When to use?

Use it to quickly find business-based dates excluding Saturday and Sunday — for delivery dates, settlement dates, or internal review periods.

How to use

  • Enter a reference date and the number of business days to move.
  • See the date N business days after or before.
  • For business days within a span, enter a start and end date.

Input Explanation

You can enter a positive or negative number of business days to move. The span calculation includes both the start and end dates.

Calculation Basis

It counts only dates excluding Saturday and Sunday as business days; public holidays and company days off are not excluded automatically.

Usage Examples

  • Calculate a deadline - Find the deadline N business days out, excluding weekends.
  • Check a settlement date - Calculate how many days after a trade the settlement business day falls.
  • Count business days - Count how many business days fall between two dates.

Examples

  • 3 business days after a Wednesday → next Monday
  • Monday to Friday span → 5 business days

Cautions

  • Public holidays, substitute holidays, and company days off are not excluded automatically. Confirm your final schedule against actual days off.
  • Time-zone settings can cause a one-day difference in some cases.

FAQ

Are public holidays excluded?

No. As a static tool running in the browser without a server, it excludes only Saturdays and Sundays.

How are business days counted?

Starting the day after the reference date, it counts only weekdays, skipping Saturday and Sunday.

What if the start date is a weekend?

Weekends are excluded, and counting proceeds from the nearest following weekday.

How do I account for holidays?

Holidays are not applied automatically, so add the number of holidays to the result manually.
