I have some simple date calcs in a define but need to show both in calendar & business days. Has anyone done business day calculations?

Not sure exactly what your doing in your calculations but if you were adding using DATEADD

then it would be

DATEADD(DATE1, 'BD', 1);

BD represents business day which can be configured by using the SET method.

To see what are business days
? SET BUSDAYS (i think the default is M-F)

SET BUSDAYS = '_MTWTF_'; either have the first letter of the day or an underscore if its not a business day.
If you wanted to include Saturday as a business day then it would be
SET BUSDAYS = '_MTWTFS';

Hopefully its what your looking for,

Thanks Leo. I had a bit of a brain freeze. I got it using DATEDIF.
