Question : NETWORKDAYS substitute

What can i use for a NETWORKDAYS substitute.

My spreadsheet contains extensive Macros and Sheet formulae and i can't always assume the User has (or knows how to) installed the Analysis toolpak.

i would prefer VBA, but a traditional formula would be ok.

it must be able to handle Holidays.
