Please Help - Formulas and Dates

[TheAlchemist]

Hello,

I am trying to create a column that would take a date from one cell and add 9 Months and 1 Day, therefore returning a date of 9 months and 1 day later. My issue is, while using the normal date on 31/12/2020 and 05/04/2020 dates, I get 02/10/2021 (wrong) and 06/04/2021 (right) dates. I need the date to be exactly 9 months and 1 day post the above dates but can not find a way to have it shown. 

Please help.

My formula atmo - =IF(QIPS?>0,"N/A - QIPS",DATE(YEAR([Year end])+0,MONTH([Year end])+9,DAY([Year end])+1))

@TheAlchemist 9 months and 1 day is 274.75 days, so why not just have a calculated column that adds that to the date i.e =[Review Date]+274.75

Hi Thank you!
Unfortunately as you can see the 5 April date gives you a day before not after :( Therefore some errors will occur. On excel you can do what I need to do by using EDATE, sadly SharePoint doesn't have that function :(
