- Choose a date range or working-day offset.
- Set the workweek and start-date rule.
- Enter any company closures or holidays, then copy the result.
The USA and India presets start with a Monday–Friday workweek. If your team works Saturdays, choose Sunday only as the weekend. The USA preset can optionally exclude observed federal holidays for 2026 and 2027. Enter local holidays and company closures separately. For India, enter the state and employer holidays that apply to your team. The calculator uses calendar dates and includes the end date in range mode. Switch on the start-date option when the first day should count, provided it is a working day.
Example
From Monday, January 5, 2026, through Friday, January 9, 2026, there are five calendar days and five working days when both endpoints count. Excluding Wednesday gives four working days.
Frequently asked questions
Are public holidays automatically excluded?
The optional US federal schedule covers 2026 and 2027. For state, employer, and Indian holidays, enter the dates your business observes. A closure on a weekend is counted only once.
How do I subtract working days?
Choose the offset mode and use a negative number. The same weekend and closure rules apply when counting backward.
Does a zero offset move to the next working day?
No. Zero returns the selected date.
