What counts as a business day here
A business day is any Monday to Friday. This count includes both the first and last date when they fall on a weekday, like the NETWORKDAYS function in spreadsheets. If you want to leave the end date out, the answer is 65 business days. Public holidays are not removed, so take off any that fall in this range.
Working hours in the range
At eight hours per business day, 66 business days come to 528 working hours, or 13.2 standard 40-hour weeks. Each public holiday you observe removes one day and eight hours.
Why it differs from the calendar count
The range starts on a Thursday and ends on a Thursday. Five days in every seven are weekdays, so 92 calendar days would give roughly 66 weekdays. The exact figure depends on which weekday the range starts on, and here it is 66.
