What counts as a business day on this page?

On this page, a business day means a weekday that is not listed in your custom holiday input. When weekend exclusion is turned on, Saturdays and Sundays are skipped.

Can I count workdays between two dates?

Yes. Use the Business Days Between Dates mode, enter a start date and end date, and the page will count the valid workdays in that span.

Can I find what date is 10 business days from today?

Yes. Switch to Add / Subtract Business Days, use today or another base date, and add 10 business days. The result will show the resulting workday and weekday.

Can I add business days to a date?

Yes. Switch to Add / Subtract Business Days, choose add or subtract, and enter the number of business days you want to move.

Do holidays count automatically?

Not automatically. You can add custom holiday dates manually, and the calculator will skip them.

Why is this page different from the date calculator?

The date calculator focuses on general date difference and add/subtract tasks. This page focuses on workday logic where weekends and custom holidays may need to be excluded.

How this business days calculator works

This page treats business days as weekday-aware dates rather than simple calendar days. It can count workdays between dates or calculate what date lands after adding or subtracting business days while skipping weekends and custom holiday dates.

1. Choose the workday task

Use the first mode to count business days in a range, or the second mode to move a date by a number of business days.

2. Add dates and optional custom holidays

Enter the dates you want to compare or shift. If needed, add your own holiday dates in YYYY-MM-DD format so they are skipped.

3. Review the workday-aware result

The result shows business days, excluded weekend or holiday days, and the resulting workday when you shift from a base date.

Why this page is separate from the main date calculator

General date math and business-day logic are related, but they are not the same user task. Workday calculations need weekend and holiday rules that do not belong on the simpler date page.

Queries like "how many business days between two dates" or "what date is 10 business days from today" belong here because they depend on workday rules rather than raw calendar difference.

This page supports weekday exclusion and custom holiday dates entered manually. It does not yet load country-specific holiday calendars.

If you are planning SLAs, delivery windows, PTO ranges, or office workflows, business days are often more useful than raw calendar days.

A business-day shift can cross many calendar days even when the workday count is small, because weekends and holidays may be skipped.
