Change the week period on differenceInBusinessDays?

[Stuart-wdas]

I am trying to make use of the differenceInBusinessDays and so far the function has been superb, but im wondering if there is a way to change the period of a business week i.e. the default is currently 5 - 2, 5 working days 2 weekend days, is there a way to change the options on the function so the period is 6 - 1, 6 working days 1 weekend day? const working_days = differenceInBusinessDays(current_date, previous_month, options: { business_days: 6 });
