Create Column with Last 3 Months

Hi,

I have a date column and I am trying to create a calculated column that contains the dates from current date and shifts back 3 months. So far I noticed it is possible to use DATESBETWEEN or DATESINPERIOD in a CALCULATE function but they can't be used independently which is what I am trying to do. Is there a way I can do this? Here's the dax code I had for my calculated column;

Last3Months = DATESINPERIOD('All Stations'[Date],TODAY(), -3,MONTH)

Here's the error I get;

A table of multiple values was supplied where a single value was expected.

Thanks for your help.
