Excel/VBA equivalent to DateAdd() function

Does anybody know if there is a function (Excel or VBA) that can add workdays to a date?

Similar to the DateAdd("d",5,dDate) but in stead of adding 5 days to the date it must add 5 workdays to the date.

Or does anybody know how to do such a thing? Added complication would be public holidays that must also be excluded.

Thanks shg.

For some obscure reason, when looking for the function last night, I thought the Workday function returns a true or false if a specific day is a workday. And it's not as if I hadn't used it a bunch of times before How stupid can one get Hope it was just tiredness and not Alzheimer's!
