Count working days between two dates and choose the workweek that matches your schedule.
How to calculate business days between two dates
A business day, working day or workday is any day included in the selected workweek. Monday–Friday is the default, while Sunday–Thursday and Monday–Saturday are available for workplaces that use different schedules.
Holiday notePublic and company holidays vary by location and employer, so this calculator does not silently guess them. Subtract any applicable holidays when your deadline or policy requires it.
When working-day counting matters
Business-day calculations are useful for delivery promises, payment terms, processing times, service-level agreements, HR deadlines and project schedules where non-working days should not count.

Common questions
Are business days and working days the same?
They are commonly used to mean the same thing: days included in a normal workweek. This calculator lets you choose the workweek rather than assuming every schedule is Monday–Friday.
Does the calculator exclude public holidays?
No. Public and company holidays are not removed automatically because they differ by location, employer and year.
Are the start and end dates included?
Use the “Include eligible boundary dates” option. When enabled, a boundary date counts if it is a working day under the selected workweek.
