Questions
Are public holidays excluded from weekdays?
No — weekdays counts Monday to Friday only. Check the public holidays page and subtract any that fall in your range.
Is the end date included?
The day count is the difference between the dates, so the end date is not counted. Add one if you need an inclusive count.
