Embed this calculator

Calculate the number of business days between any two dates, add or subtract working days from a start date, or find Net 30/60/90 payment deadlines, all with the holiday calendars of 25 countries: the US, UK, Canada, Australia, Brazil, China, Egypt, France, Germany, India, Ireland, Israel, Italy, Japan, Mexico, New Zealand, the Philippines, Qatar, Saudi Arabia, Singapore, South Africa, Spain, Switzerland, the UAE, and Vietnam. Use it for invoice due dates, SLA commitments and project timelines; for a court or statutory deadline, check the counting rule that governs it before you rely on a business-day count.

25 country holiday calendars

Each country's calendar is the holiday list in that country's data file, and the Holiday Sources page names the official list each one is read from. Pick a country in the dropdown above to apply its calendar to your calculation.

Frequently Asked Questions

What is a business day?
On this site a business day is a day that is neither a weekend day nor a holiday in the selected country's calendar. The calculator takes Saturday and Sunday as the weekend for 21 of the 25 countries, Friday and Saturday for Saudi Arabia, Qatar and Egypt, and Saturday alone for Israel, so its Israeli count runs Sunday to Friday. With Israel selected, a Working week control appears under the Holiday Calendar dropdown with two choices, "Sunday to Friday (Bank of Israel payment system)", the default, and "Sunday to Thursday (government ministries)", and it links the source for each. A contract or statute can define a business day differently, and where it does, its definition is the one that counts. The working days calculator runs the same count under that name.
How do I calculate business days between two dates?
Use the "Between Dates" tab, enter your start and end dates and pick a country in the Holiday Calendar dropdown: the calculator shows the business days, the calendar days and the approximate weeks between them. The days between dates tool does the same on a page of its own.
Does the calculator account for public holidays?
Yes. Pick a country in the Holiday Calendar dropdown and the calculator leaves that country's holidays out of the business-day count. The 25 countries are the US, UK, Canada, Australia, Brazil, China, Egypt, France, Germany, India, Ireland, Israel, Italy, Japan, Mexico, New Zealand, the Philippines, Qatar, Saudi Arabia, Singapore, South Africa, Spain, Switzerland, the UAE, and Vietnam; choosing "No holidays (weekends only)" counts weekends alone.
What is a Net 30 payment term?
This site reads Net 30 as payment due 30 days after the date you enter, for example the invoice date; your contract decides which date the count starts from and whether the days are calendar or business days. The Net 30 payment calculator (or Net 60 / Net 90) counts 30 calendar days by default and can switch to 30 business days, which skips weekends and the selected country's holidays.
Can I share my calculation result?
Yes. The page address updates with your inputs as you calculate, so the URL reopens the same calculation, pre-filled, for anyone you send it to. The link button under the result copies it in one click.
