Business Days Calculator.
Count working days between any two dates. Automatically excludes Saturdays and Sundays to help you plan project milestones, sprints, and payroll periods.
How Business Days Calculation Works
A business day (or working day) refers to any official workday from Monday through Friday. Saturdays and Sundays are classified as weekend days and are excluded from working duration calculations. In corporate environments, calculating business days is essential for:
- Agile Sprints & Engineering Deadlines: Estimating project delivery timelines based on actual developer working days rather than calendar duration.
- Service Level Agreements (SLAs): Measuring turnaround times (e.g., "resolves within 3 business days").
- Banking, Clearing & ACH Transfers: Federal reserve and banking settlement days only operate on non-weekend business days.
- HR, Leave Management & Payroll: Calculating paid time off (PTO) and working days per month.
Frequently Asked Questions
Are weekends included in business days? ▼
No. Standard business days only count Monday, Tuesday, Wednesday, Thursday, and Friday. Saturdays and Sundays are excluded automatically.
Should I include the end date in the count? ▼
By standard convention, the start date is counted and the end date represents the deadline boundary. If your work continues through the final day, enable "Include end date" in the options.
