Date Formulas

[dwool40]

I am currently using the following formula to get dates:

=IF(ISBLANK(A22),"",IF(C22="Y",D22+18,WORKDAY(I22,1,Holidays!$B$1:$B$5)))

If I get more than 2 dates, for example 07/16/2019 four times, is there a way to add 1 day to the extra 2 dates? I do not want to have more than 2 of the same date.

Are these dates (and formulas ) in a column? You could then count the number of occurances above and if so add 1.

What is held in the various columns A, C, D, I?

Assuming the rows run from row 2 to xx, then for cell B22 it would be something like (not tested)

=IF(ISBLANK(A22),"",IF(COUNTIF(IF(C22="Y",D22+18,WORKDAY(I22,1,Holidays!$B$1:$B$5)),B$2:B21)>1,IF(C22="Y",D22+18,WORKDAY(I22,1,Holidays!$B$1:$B$5))+1,IF(C22="Y",D22+18,WORKDAY(I22,1,Holidays!$B$1:$B$5))))
