SharePoint 2010 - Calculated Column - factor in holidays and weekends in date difference formula

Walter Curtis
Last Modified: 2017-04-27
I am successfully calculating the difference between two dates ("Start Date" and "End Date") using a calculated column named "Project Length". The business requirements however are to factor in weekends and holidays in my final result.   There is a function in Excel named "NetworkDays" that will do these type calculations in Excel, but it does not work in SharePoint 2010. Note:  Adding an additional list to hold the holiday values is not a problem.

If anyone has information about how to accomplish this, it would be greatly appreciated if you would let me know.

Many Thanks...

Thanks Tim for the link. I have studied that article, the title is somewhat deceiving because they show a unique requirement of determining a date and excluding weekends.

Yes, I am trying to remove weekends and holidays from the final results.
