Working Days Calculator
Last reviewed: October 14, 2026
Count working days between two dates, add working days to a start date, or subtract them to find an earlier date. Here working days and business days mean the same thing: the days of the selected country's working week, minus its public holidays. The calculator counts that week as Monday to Friday for 21 of the 25 countries, as Sunday to Thursday for Egypt, Qatar, and Saudi Arabia, and as Sunday to Friday for Israel.
This calculator has holiday calendars for 25 countries: the US, the 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. Pick the country whose calendar governs the deadline. Each country's holiday set is the one its own page lists with its source. It is one list per country (for the UK, the bank holidays of England and Wales), so a holiday that your state or region adds may not be in it; the calculator's Advanced options let you add such days as custom dates.
