One thing unclear (to me). You want to pick a whole date range? If just one day, maybe all you need is a combo that defaults to Date() + 3 (using DateAdd function) but provides some other values around that in case of paid holidays. You could also easily find code for a custom calendar, but you'll need to build a supporting form with 42 controls for dates, so it might not be worth the work for picking just one day.
The more we hear silence, the more we begin to think about our value in this universe.
