How to use this calculator

  1. Pick the start and end dates. Both are counted.
  2. Choose your weekly off days.
  3. Enter how many public holidays fall on working days.
  4. Read the working days.

The formula

Total days = End − Start + 1. Weekly off days are counted by checking each day. Working days = Total − Weekly offs − Public holidays.

Worked example

From 2 November to 30 November 2026 there are 29 days, of which 8 are Saturdays and Sundays. With 2 public holidays on working days, there are 19 working days, or 3.8 working weeks.

Understanding your result

Both the first and the last day are counted. Enter only holidays that fall on a working day, otherwise they will be taken out twice.

When to use it

  • Estimate delivery or project time in working days.
  • Work out salary days or leave balance.
  • Check notice periods counted in working days.

Assumptions and limits

Holiday dates differ by state and employer, so enter the count yourself. Use the Business Days Calculator to find an end date from a start date.
