H1_Work Days Calculator - Business Days Between Dates | MultiTool

How it works

Enter a start and end date, optionally list holidays in YYYY-MM-DD format (comma separated), and the tool counts the business days between them, excluding weekends and any holidays you provide.

Business days, explained

A business day is any day that is not a weekend day — that is the convention contracts, banks and shipping companies use. This calculator counts days excluding Saturdays and Sundays, which matches the default almost everywhere in the world.

• Holidays vary by country: national and local holidays are not subtracted automatically. If your deadline is “5 business days” and there is a holiday in between, add it manually to be safe.
• Counting conventions differ: some contracts count the start day, others do not. If the result matters legally, check which convention applies — the difference is one full day.
• Deadlines that land on a weekend usually slide to the next business day in most jurisdictions — but verify for your case.

Common uses: SLA and delivery deadlines, notice periods in contracts, project planning, payroll and overtime windows, and “respond within X business days” promises. For plain calendar differences (weekends included), use the Date Calculator.
