Date Calculation Formula to Return Friday of Week Calculated

I'm looking to return the Friday of the week that my date calculation result falls.

For instance, I have a formula that calculates a Start Date by using "Due Date" - 40 WORKDAYS. I need to then have the result show the Friday of that week. My first WORKDAY formula works fine on its own, but not with IF(WEEKDAY...... added.

Based on other searches I tried:

=WORKDAY([Due Date]955, -40) + IF(WEEKDAY (WORKDAY ([Due Date]955), -40) <6, "6"))

Also tried:

=IF(WEEKDAY(WORKDAY([Due Date (Pagination)]959, -45)) < 6, 6)

Neither worked. How do I enter this formula?

This may not be the most elegant solution, but it gets the job done for me.

First, place a helper column with the formula below; in this example the helper column is named "Column":

=WORKDAY([Due Date]@row, -40)

Next, in the Start Date column, place the following formula:

=IF(WEEKDAY(Column@row) = 1, (Column@row + 5), IF(WEEKDAY(Column@row) = 2, (Column@row + 4), IF(WEEKDAY(Column@row) = 3, (Column@row + 3), IF(WEEKDAY(Column@row) = 4, (Column@row + 2), IF(WEEKDAY(Column@row) = 5, (Column@row + 1), IF(WEEKDAY(Column@row) = 6, (Column@row), IF(WEEKDAY(Column@row) = 7, (Column@row + 6))))))))

Note that Saturday and Sunday are included in the above formula.

@Kelly P.

Thanks for getting back to me. I'll try that out. I was thinking a helper column may be needed, but was trying to avoid the extra column on the sheet. As long as it works, it will do.

Thanks so much!
