Previous Business Day Calculator

How it works

The calculator moves one calendar day at a time until it finds a weekday that is not listed as a public holiday for the selected country.

This is useful when a date lands on a weekend or public holiday and you need the last normal working date before it. Common examples include choosing a payroll cut-off, checking the last business day before a month end, setting a reminder before a bank holiday, or finding the previous support day before a delivery promise.

When to use the previous business day

• Month-end, quarter-end, or year-end reporting checks.
• Invoice chasing where the due date falls outside normal office days.
• Internal reminders before a public holiday or long weekend.
• Support, HR, payroll, and operations tasks that need a working-day handover.

The result is a practical planning answer, not a substitute for the rule behind a formal deadline. Some contracts, courts, regulators, or payroll processes specify whether the date rolls forward, rolls backward, or is handled in a different way. Always check the original rule when the consequence of a missed date is significant.
