Business Days Calculator

The Business Days Calculator computes the exact number of working days between two dates, excluding weekends (Saturday and Sunday by default) and configurable public holidays. Accurate business day calculation is essential for contract law (net-30/net-60 payment terms), project management (sprint planning, milestone tracking), financial settlement cycles (T+2, T+3), SLA compliance, and shipping estimates. The tool correctly handles edge cases where a start or end date falls on a weekend or holiday.

How to Use

Enter a start date and end date to count business days between them, or enter a start date and a number of business days to compute the target date. Configure the working week (5 or 6 days), select country-specific public holiday calendars if needed, and toggle individual holiday dates. Results show the business day count and the next working day if the target falls on a weekend.
