Hi,
Try the following...
<pre>=A1+IF(WEEKDAY(A1,2)<=5,5,12)-WEEKDAY(A1,2)</pre>
Change the test to <5 rather than <=5 to get the date to rollover on a Friday, rather than report the Friday date.
WEEKDAY may be an Analysis ToolPak add-in function. If so, you will have to load it before you can use it.
