A business day follows the working week and custom holidays you select.

Count business days

Choose whether the first and last date count. Then each included date is checked against your weekend pattern and custom holiday list.

Included dates − weekend dates − weekday holidays = business days

Add or subtract workdays

Positive numbers move forward; negative numbers move backward. Counting begins on the day after—or before—the start date, and skips every excluded date.

Start date ± working days = deadline date

Business-day questions

What counts as a business day?

Usually it is a regular working day that is not a weekend or holiday. Contracts, employers and countries can define it differently, so choose the schedule and exclusions that apply to you.

Does the start date count?

For a date range, use the endpoint menu to include or exclude either date. When adding or subtracting workdays, counting starts after the selected start date.

Does this include public holidays automatically?

No. Holiday calendars vary by country, region and employer. Add the exact dates you need excluded to keep the result transparent and accurate for your situation.

Can I use a Friday–Saturday weekend?

Yes. Select the Sunday–Thursday working week. You can also choose a six-day week or treat every calendar day as a working day.
