A business days calculator answers a deceptively common question: how many working days sit between two dates? Delivery promises, invoice terms, notice periods, support SLAs, project plans, and payroll cutoffs are usually written in business days rather than ordinary calendar days. Counting them by hand is easy to get wrong when a range crosses a weekend, a public holiday, or the end of a month.
GeoTimeTools counts Monday through Friday and can remove public and bank holidays from the country calendar you choose. Select Weekends only for a weekday count, or choose a country to apply its built-in 2026 and 2027 holiday dates. The results separate business days, weekdays, weekend days, and public holidays, and list the holiday dates that fall inside the considered range. That makes the result easier to audit than a single unexplained number. The calculator is intentionally browser-only, so dates are calculated on your device and nothing needs to be uploaded.
Use this working days calculator for a quick planning estimate, not as a legal or contractual interpretation. Different organizations define a working day differently, and some observe company closures or regional holidays. If your deadline depends on a special calendar, use the result as a starting point and compare it with the policy that governs your project. The page is especially useful for phrases such as “10 business days from today” or “30 business days from the order date.”
Calendar days versus business days
Calendar days include every date in the selected range. Business days keep weekdays and remove weekends, with a selected country calendar also removing its public and bank holidays. The include-start and include-end controls matter because “within five business days” and “five business days after” can use different counting conventions.
Country holiday calendars
The country options use the public and bank holiday dates stored for 2026 and 2027 in GeoTimeTools’s calendar data. Regional rules, substitute days, company closures, optional holidays, and observances can differ, so confirm an official local schedule when a deadline has legal, payroll, or contractual consequences.
