Business Days Calculator
Count working days between dates, add business days to a date, or find how many days until a deadline — weekends & holidays excluded automatically.
How to Calculate Business Days
Business days — also called working days — are weekdays (Monday–Friday) that are not public holidays. Banks, courts, governments, and most companies operate exclusively on business days.
Between Two Dates
Select a start and end date, choose your country, and the calculator counts every weekday in that range, automatically skipping weekends and official public holidays. Useful for contracts, legal deadlines, invoices, and project timelines.
Add Business Days to a Date
Enter a starting date and the number of business days to add. The calculator skips over weekends and holidays to land on the exact calendar date. Common uses: shipping estimates, payment terms (net 30), legal response windows.
Days Until a Deadline
Enter a target date to see how many business days remain from today. Ideal for deadline tracking, project milestones, and time-sensitive government filings.
Why Results Differ by Country
Each country has different public holidays. A 60-day period can be 42 business days in the US but only 40 in Colombia. Always select your country for accurate results.
Supported Countries
United States, United Kingdom, Canada, Australia, Germany, France, Spain, Mexico, Brazil, Colombia, Argentina, Venezuela, India, and Japan. Floating holidays like Easter and Thanksgiving are calculated dynamically for any year.
