NZ Working Day Calculator Features & Tools

Deadline Date Calculator

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

Working Days Between Dates

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 in calculations so the count can match the wording or assumptions relevant to your context.

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 common NZ shutdown windows such as ADLS, ADLS LIM, courts-style, or RMA-style counting ranges.

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

Verification

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

Calendar Day Counting

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