Preguntas frecuentes

What counts as a business day?

In CivicCalendar a business day is a Monday–Friday that is not a legal holiday in Australia. Saturdays and Sundays are not counted.

Is the start day included?

Yes. In “Between two dates” mode both dates are inclusive. In “Add business days”, counting starts on the start date if that date is a business day.

Are regional holidays considered?

National holidays and regional holidays defined for the country are used. If a regional holiday does not apply to your area, the result may differ.

Is this an official calculation?

It is indicative according to current legislation and calendars loaded on the site. For critical legal or labor deadlines, confirm with the relevant rule or authority.
