Frequently asked questions
Are state public holidays included?
No. Only nationally observed public holidays are included. State and territory holidays such as Labour Day and regional show days vary by location and are not counted.
What does 'include end date' do?
It determines whether the final day of the range is counted as a whole day, which changes totals by one.
Does this handle leap years?
Yes. All calculations use calendar dates, so leap years are automatically accounted for.
