Frequently Asked Questions
How do I calculate business days between two dates?
Business (working) days exclude weekends and public holidays. Our calculator automatically subtracts Saturdays, Sundays and Australian national public holidays from the total calendar days to give you the exact count of working days.
Does the calculator account for Australian public holidays?
Yes. The calculator includes Australian national public holidays (New Year's Day, Australia Day, Good Friday, Easter Saturday, Easter Monday, Anzac Day, Queen's Birthday, Christmas Day and Boxing Day). State-specific holidays are not included.
How many working days are in a year in Australia?
A typical Australian year has approximately 250-252 working days after excluding 104 weekend days and 8-10 national public holidays from 365 days. State-specific public holidays reduce this further.
Can I use this for calculating notice periods?
Yes. Employment notice periods in Australia are typically counted in calendar days or weeks, not business days, unless your award or agreement specifies otherwise. Use our total calendar days or weeks count for notice periods.
