Subject: NETWORKDAYS etc to Stefan Nikolas)
> The existing function deals with whole days. Excel explicitly defines it that way. Even if you give it a date serial number that is noon one day to 5pm another day, it will not return a fractional number of workdays. I'm not suggesting we expand it to include such a feature. My interest was purely in the internationalization aspect, that the legal definition of the work week in some nations is not M-F. So, we handle it by simply adding an optional enumeration value which defines what a weekend is. 0 (default) = Sat/Sun, 1=Thurs/Friday and 2=Friday/Sat. > If we wanted the full generality, we could have instead an optional array parameter of 7 values, evaluated as booleans for whether that day of the week is a weekend or not. That has the advantage of working for partial week schedules as well as 1-day weekends. You can encode this as one number while allowing more generality - encode as bits. E.G., if Sunday=1, Monday=2, Tuesday=4, Wednesday=8, Thursday=16, Friday=32, Saturday=64, then: Skip Saturday and Sunday = 65 Skip Thursday and Friday=48 Skip Friday and Saturday=33 Skip ONLY Sunday=1 --- David A.
