Practical example: a 10-business-day review
If a review starts on Monday and requires 10 business days, choose Add business days, enter the start date and 10, then select the applicable holiday calendar. Add internal shutdown dates as custom exclusions before downloading the CSV for your project record.
FAQ
Business-day calculation questions
What counts as a business day?
By default, Monday through Friday count as business days. Saturdays, Sundays, selected nationwide holidays, and your custom excluded dates do not.
Are the start and end dates included?
You control both boundaries when counting a date range. For adding business days, counting begins after the selected start date.
Does the calculator include regional holidays?
The built-in calendars focus on common nationwide dates. Add state, provincial, religious, company, or one-off closures under custom excluded dates.
What is included in the CSV?
The file records the calculation type, inputs, settings, final result, and a dated ledger showing workdays, weekends, holidays, and custom exclusions.
Do you upload or store my dates?
No. The calculation, share-link creation, and file download run in your browser without sending the entered dates to a server.
