Hi @mdrammeh,

 

Based on my test, your formula should work in Query Editor, Custom Column under Add Column tab.

You are trying to use Power Query "M" functions in DAX. You can't do that.

 

You want to use functions from here:

Specifically, probably the DATEADD function or something like it:

Refer to my blog article here on the Languages of Power BI
