How do I add add a new date column exactly two years from another date column?

[Anonymous]

Hey team,

I have a question on how to create a new date column with DAX.

I have a column with a certain start date and a second column that may or may not have an end date. I now wish to create a new end date column that has an end date two years from the start date, if the end date column is blank. If the end date column is not blank, then the end date remains the same. So the logic is essentially this:

New End Date = 

IF(ISBLANK('Table'[End Date]), 
+2 years from Start Date Column,
'Table'[End Date])

I have also visualised it:

Start Date	End Date	New End Date
17/09/2020	<blank>	16/09/2022
14/10/2020	13/02/2023	13/02/2023

So as you can see, I'm a little lost when it comes to writing the +2 years from Start Date Column.

Hi, @Anonymous 

Please try to write the below for creating a new column.

New End Date Column =
IF (
NOT ISBLANK ( 'Table'[End Date] ),
'Table'[End Date],
DATE ( YEAR ( 'Table'[Start Date] ) + 2, MONTH ( 'Table'[Start Date] ), DAY ( 'Table'[Start Date] ) )
)

newenddate =
IF (
    ISBLANK ( 'Table'[End Date] ),
    DATEADD ( 'Table'[Start Date], 2, YEAR ),
    'Table'[End Date]
)
