What Is a Business Days Calculator?
A Business Days Calculator counts working days between two dates while allowing weekends and specified holidays to be excluded. Business days commonly refer to Monday through Friday, although working-week schedules can differ by country and organization.
This calculator is useful for project schedules, delivery estimates, invoices, payment terms, work deadlines, contracts, administrative planning, and other date-based calculations.
Business Days = Calendar Days − Excluded Weekend Days − Eligible Holidays
Because holiday schedules differ between countries, regions, companies, and industries, this tool lets you manually enter the holidays you want excluded.
How Does the Business Days Calculator Work?
The tool checks each date within your selected period and determines whether it should count as a working day.

What Counts as a Business Day?
A business day generally means a day on which normal business operations take place. In many workplaces, Monday through Friday are considered business days, while Saturday and Sunday are treated as weekends.
However, there is no single schedule that applies everywhere. Some businesses operate six or seven days per week, and weekend days differ in some locations and industries.
Weekends
By default, this calculator excludes Saturday and Sunday. You can turn either exclusion off if your work schedule includes one of those days.
Public Holidays
Public and company holidays may also be excluded from business day calculations. Since holidays vary by location and employer, you can enter specific holiday dates manually.
Start and End Dates
The calculator includes the start date when it qualifies as a business day. You can also choose whether the end date should be included.
Common Uses for a Business Days Calculator
Business-day calculations are useful whenever a deadline or duration is based on working days rather than every calendar day.
- Calculate project and task deadlines.
- Estimate shipping and delivery periods.
- Calculate invoice and payment terms.
- Plan employee work schedules.
- Estimate processing times.
- Calculate contract or administrative deadlines.
- Count working days within a reporting period.
- Plan business operations around holidays.
Business Days Calculation Example
Suppose a date range contains 14 calendar days. If four of those dates are Saturdays or Sundays and one additional weekday is an excluded holiday, the calculation would be:
The exact result depends on which dates are included, which weekend days are excluded, and whether any entered holidays fall on otherwise valid business days.
