Idea: I need a function that given two dates, will return the number of business days between them. I need to know the # of business days between when a sales order is placed and when it ships to the customer. I'm in the US, so I would want to not count Saturdays, Sundays, and US Holidays, but I can foresee others wanting the option to change to other calendars or ignore holidays.
There are a couple of posts on this in the community, but everything I've found so far is too laborious to implement or not robust.
