NZ Working Day Calculator Features & Tools

Calculate a deadline date by counting forward or backward using working days or calendar days.

Count the number of working days or calendar days between two dates with the same holiday and shutdown assumptions.

Control whether start and end dates are included. The linked guide explains how section 54 statutory wording maps to those calculator settings.

Include the relevant regional anniversary day, or combine regions when you need a broader planning view.

Automatically accounts for New Zealand public holidays, including observed holidays when statutory holidays fall on weekends.

Apply NZ summer windows such as the ADLS sale and purchase agreement, the ADLS agreement LIM date, the High Court Rules summer exclusion, or the Resource Management Act definition.

Chain multiple working-day periods where each result becomes the next start date, useful for staged transactions, approvals, and project timelines.

See which dates were excluded from the count and why, so the result is transparent and easy to check.

Switch to straight calendar-day counting when you need simple date arithmetic rather than a working-day result.
