Twenty-five country holiday calendars
The calculator factors in federal, bank, gazetted, and regular holidays for these twenty-five countries. Pick a country in the dropdown above to apply its calendar to your calculation.
A business day is any day that is not a Saturday, Sunday, or public holiday. Typically Monday through Friday are business days. The exact definition can vary by country and industry, but most financial, legal, and commercial deadlines use this standard definition. You can also view our working days calculator for regions that use that terminology.
How do I calculate business days between two dates?
Use the "Between Dates" tab, enter your start and end dates, select your country's holiday calendar, and the calculator instantly shows the number of business days, calendar days, and approximate weeks. Or navigate directly to the days between dates tool.
Does the calculator account for public holidays?
Yes. Select your country or region from the Holiday Calendar dropdown and the calculator will automatically exclude public holidays from the business day count. Supported regions include the US, UK, Canada, Australia, Brazil, China, Egypt, France, Germany, India, Ireland, Israel, Italy, Japan, Mexico, New Zealand, Philippines, Qatar, Saudi Arabia, Singapore, South Africa, Spain, Switzerland, the UAE, and Vietnam.
What is a Net 30 payment term?
Net 30 means payment is due within 30 days from the invoice date: either 30 calendar days or 30 business days depending on your contract. Use our dedicated Net 30 payment calculator (or Net 60 / Net 90) to instantly find the exact due date from any starting date, accounting for weekends and holidays.
