How to calculate a due date based on a project deadline?

Leslie Kuhlman

I have a tracker that completes the due date for each line item based on the final deadline through either adding or subtracting. Is there a way to do the same in Smartsheet.

Deadline 10.15.2022, Budget Development needs completed 270 in advance.

Excel formula | =10/15/2022 - 270 = 01/18/2022

Any help would be greatly appreciated.

=[Due Date]@row - 270

• Will backtrack 270 calendar days.

=Workday([Due Date]@row , -270)

• Will backtrack 270 working days.

I'm sorry, I missed the context that the due date was in the first row...

=Workday([Due Date]1 , -270) will calculate the due date for you. 😁
