How to determine the weekday in excel?
 

Does anyone know on how to determine the date for weekday? such as
Today is wednesday 29 Nov, and I would like to determine the date by adding
11 working days from today, but not include today, and exclude all saturday
and sunday.
The answer is 14 Dec.
I will input the number of working day [11] in cell A1, and the 14 Dec is
displayed on B1.
Does anyone have any suggestion on how to code it in excel?
Thanks for any suggestions
Eric
