Excel/Due Dates


I work in construction. We'd like to know if there is a way to work a calendar backwards. We have a "due on site" date, a material lead time and need to figure out when the item needs to be approved by in order to meet the "due on site" date.

Please help, thank you for your time.


Hi Katy
How are you?

You can substract and add days to any date as if it were simple numbers:

the due date  in C1
the number of days  that takes to receive the part in B1
the orderīs date should be in A1

if the result comes on a numeric format, just change it to a date format.
