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.
