How this calculator works

This working days calculator measures business days between dates using your chosen work schedule. By default, working days exclude weekends on Saturday and Sunday, but you can switch to Friday–Saturday, Sunday only, or a custom weekend pattern that matches regional or industry calendars.

Turn on Exclude public holidays to remove official public holidays from the count. Choose a country to load a bundled national holiday calendar covering fixed dates and recurring observances such as Easter-linked holidays, so your business day calculations reflect country-specific business days rather than a generic weekday guess.

Results show total business days, how many weekend days were excluded, how many public holidays were excluded, and a dated list of each national holiday that affected the range—giving you a transparent business calendar for payroll, contracts, shipping, and compliance reviews.

Worked example

Suppose you need to calculate working days between dates for a US contract window from Monday, December 22, 2025 through Friday, January 2, 2026. Select United States, enable Exclude weekends and Exclude public holidays, and keep the Saturday & Sunday weekend schedule.

That span includes two full weekends plus Christmas Day (December 25) and New Year's Day (January 1). The business days calculator excluding holidays removes those non-working days and reports the remaining business days between the start and end dates, listing each excluded public holiday with its date so you can verify the business day count against your contract or SLA.

Practical use cases

Payroll and HR teams use a business days calculator with holidays to count processing windows, leave accruals, and notice periods in working days excluding public holidays. Finance and banking teams apply net terms and settlement rules that depend on business days by country rather than raw calendar days.

Legal and compliance teams measure filing deadlines, cooling-off periods, and contract delivery windows where business days excluding weekends and official public holidays define the obligation. Procurement and project planning teams estimate hand-offs, milestone dates, and vendor SLAs on a national business calendar.

Shipping and logistics teams interpret carrier quotes stated in business days, while government and public-sector teams track working days between dates for permit timelines, grant cut-offs, and regulatory response windows. Select your country, review excluded holidays in the results, and adjust the weekend schedule when your work week differs from the default.

Use the Add Business Days Calculator to project a future due date, or this tool to calculate business days between two fixed dates on a country-specific schedule.
