To calculate the duration of 45 business days, we need to consider that business days typically exclude weekends and public holidays. Assuming a standard workweek of Monday to Friday: – 45 business days would be equivalent to 9 weeks (45 days ÷ 5 days/week = 9 weeks).
A business day refers to any day in which normal business operations are conducted. In Western countries, a business day lasts eight hours and is considered to be Monday through Friday from 9 a.m. to 5 p.m. local time. Business days do not include weekends and public holidays.
Business days are the weekdays Monday through Friday. Check Business Days Only to exclude weekend days in your calendar calculation. Check Saturday is a Business Day to include Saturdays. Holidays are not included in the calculation.
So n calendar days should be approximately n*4/7 working days. This formula is pretty good for many purposes with large numbers, and will only be off by a few days at most.
