How it works

Select two dates to calculate the number of business days between them. Choose a country to automatically exclude that nation's public holidays. Weekends (Saturday and Sunday) are always excluded.

Alternatively, add or subtract business days from a start date to find the resulting date. This is essential for deadline calculations that must account for non-working days.

Business days example:

From: Monday, Jan 1, 2024 To: Friday, Jan 31, 2024 Total days: 31 Business days: 23 Weekend days: 8 Holidays: 1 (New Year's Day)

Custom holidays can be added for company-specific closures. Track office closures, team events, or local observances not in the national calendar.
