Business Days Calculator — Count Working Days

The Business Days Calculator is a free online tool that counts the number of working days (business days) between two dates, automatically excluding weekends (Saturdays and Sundays) and optionally Brazilian national holidays. This is essential for calculating deadlines, contractual terms, delivery estimates, and any scenario where only working days count. No sign-up, no downloads — just instant and accurate results.Enter a start date and an end date, then the calculator instantly shows how many business days fall within that range. You can choose to include or exclude Brazilian national holidays (both fixed dates like Independence Day, Christmas, and New Year, and moveable dates like Carnival, Good Friday, and Corpus Christi). The algorithm correctly handles leap years and calendar boundaries to ensure precision even across multi-year ranges.Legal professionals rely on this tool to calculate procedural deadlines defined in business days by Brazilian legislation. HR managers use it to count vacation days, notice periods, and contract durations. Project managers calculate delivery schedules accounting for non-working days. Finance teams determine payment terms and invoice due dates based on business day counts. The tool also supports reverse calculation — starting from a date and adding a specified number of business days to find the target date.Business Days Calculator is part of the facilita.tools collection of free planning and productivity utilities. Available in Portuguese, English, and Spanish, it works on any modern browser and adapts to mobile screens.
