Business Days Calculator
Calculate business days or workdays between two dates, excluding Saturdays and Sundays by default and showing the calendar-day breakdown.
How this business days calculator works
Choose a start and end date. The main result counts weekdays in the selected range while excluding Saturdays and Sundays. Start and end dates are included by default, and the toggles let you change that counting rule.
Calendar days and weekend days are shown separately so you can see what was counted and what was excluded.
Weekend exclusion and limits
This calculator uses a fixed Monday-through-Friday workweek and does not automatically exclude public holidays. It is useful for simple project timelines, counting workdays until a date, checking weekday ranges, and scheduling estimates, but it is not a payroll, HR, legal, tax, contract, or compliance tool.
