need a formula
I am looking for a formula that would allow me to enter an end date for a
project and the number of weeks it would take to complete and these numbers would automatically populate a 52 week spreadsheet by filling the appropriate cells with color going back in time to give me a start date. for example if I had a completion due date of July 17th and it was supposed to take 16 weeks to complete when would I need to start? |

need a formula
If you are talking about 7-day weeks, then simply subtract 7 times the
number of weeks from your end date. If you are talking about 5-day weeks, then use the WORKDAY function (which requires the Analysis ToolPak Add-In) with -5 times the number of weeks as the number of days. So, assuming your start date is in A1 and the number of weeks is in B1, then... For a 7-day week: =A1-7*B1 For a 5-day week: =WORKDAY(A1,-5*B1) The WORKDAY function allows you account for holidays, so you may want to look at its help files. -- Rick (MVP - Excel) "Richard" wrote in message ...
