Free Online Business Days Calculator

Count working days between two dates with configurable Saturday and Sunday handling. The calculator includes the start date, excludes the end date by default, and reports business, weekend, and calendar-day totals.

Steps

How it works

  • Choose the beginning and ending dates.
  • Decide whether to include the end date.
  • Choose whether Saturdays or Sundays count as business days.
  • Calculate and review the business-day, weekend-day, and calendar-day totals.

Highlights

Key features

  • Excludes Saturdays and Sundays by default.
  • Can count either weekend day as a business day.
  • Offers optional end-date inclusion.
  • Accepts the two dates in either order.
  • Separately reports business, weekend, and calendar days.

Use cases

Common uses

  • Estimate weekday effort between project dates.
  • Count office days for a date range.
  • Compare calendar days with working days.
  • Adapt a count for workplaces that operate on Saturday or Sunday.

Notes

Limitations to know

  • Public holidays and custom holiday lists are not supported.
  • The start date is counted when it qualifies; the end date is excluded unless selected.
  • Reversed ranges are normalized rather than producing a negative count.
  • Partial workdays, office hours, and shifts are not calculated.
  • Weekend settings are limited to including or excluding Saturday and Sunday.

FAQ

Frequently asked questions

5 answers
Are weekends excluded?

Saturday and Sunday are excluded by default. Either one can be counted as a business day with its checkbox.

Are public holidays excluded?

No. The current calculator has no country holiday dataset or custom holiday input.

Are both dates included?

The start date is considered, while the end date is excluded by default. Enable Include end date to count it when eligible.

What happens when both dates are the same?

The default result is zero because the end date is excluded. Including the end date counts that date according to its weekday settings.

Is this identical to spreadsheet NETWORKDAYS?

Not exactly. It provides weekend controls but does not accept a holiday range.
