Adding Month and Days to a Cell

Lisi

Hello everyone,

I have a Completion Date of 1/08/2019 and I need the next cell to be 1/29/2019 (which is ten days before 2/8/2019) and the third cell to be 2/18/2019 (which is ten days after 2/8/2019). I've tried every which way I could think of to get this to work. Any ideas?

THANK YOU!

Are you using date type columns?

Hi Paul, 

 

Yes I am.

Ok. I asked because your Date Range End column is not showing a date format.

 

What is the logic you are using to determine the dates? Do you go one month out and then calculate 10 days on either side of that date? Or is it 30 days out, or....?
