What is Business Days Calculator?

Count business days between two dates or add and subtract working days from a date. Weekends are excluded; public holidays are not automatically removed.

Count business days between dates

Choose a start and end date to count Monday through Friday. You can include or exclude the boundary dates depending on how your deadline is defined.

Add business days from a date

Use the add-workdays mode for questions such as “What date is 10 business days from today?” The calculator skips Saturdays and Sundays as it moves forward.

Subtract business days

The same logic can move backward, which is useful for lead times, filing deadlines and planning dates before an event.

Public holidays

Holiday calendars differ by country, state and company. ToolViso does not automatically remove public holidays, so confirm holiday-sensitive deadlines with the relevant calendar.
