Example use case

Use it to calculate when an invoice should be paid in 10 business days, when an SLA window ends, or how many workdays remain before a payroll cut-off.

Frequently asked questions

Short answers to the questions people most often ask before relying on the page.

How are working days calculated?
Working days are calculated by removing weekends and the selected country holiday calendar from the date range.
Why can the same period differ by country?
The same dates can produce different totals because each country follows its own public holiday calendar.
When should I use the business days calculator?
Use it when you need to add or subtract a fixed number of usable workdays from a start date.
When should I use the between-dates or date-difference tools?
Use between-dates for country-specific workday totals and date difference for raw calendar duration.
