Holiday dates are deduplicated. Only holidays falling on a selected working weekday within the included range reduce the working-day count. No public holiday service is used.

Working days = selected weekdays in the included range − unique holidays on those weekdays

14 calendar days = 10 working + 4 nonworking. Start and end dates are counted only when selected.

Dates are calculated as calendar days in your browser, without time zones or external holiday feeds.

Frequently asked questions

Are the start and end dates included?

Both are included by default. Uncheck either endpoint to exclude it; the weekday and calendar counts reflect only included dates.

Can I choose a Sunday–Thursday workweek?

Yes. Use the Sunday–Thursday preset or select any custom combination of working weekdays, with at least one day selected.

How are holidays handled?

Paste dates in YYYY-MM-DD format separated by commas or lines. Duplicates are removed; only holidays on included working dates reduce the total.

What are nonworking days?

Nonworking days equal included calendar days minus working days, including both unselected weekdays and manually excluded working-day holidays.

Does it handle leap years or reversed dates?

Yes. Leap days and month boundaries use Gregorian calendar dates. End dates before the start date are rejected.

Is this a business-date offset calculator?

No. This counts working days within a range. Business Days Calculator instead adds or subtracts an offset to obtain a resulting date.
