Filtering with dates

[Chenz55]

Hi,

I'm new to DAX queries and trying to use the below code although I keep getting an error.

I want to filter based on the last 2 years of data based on todays date.

My Date_Rd column is in a string format.  I keep getting an error for some reason.

Any help is greatly appreciated.

Thanks

EVALUATE
FILTER(
    'values',
    DATEVALUE('values'[Date_Rd]) >= TODAY() - 730
)

Hi @Chenz55 ,

What is the format of your [Date_Rd] column?

Try to convert it first. Here’s an example of how you can do this if your dates are in the format DD/MM/YYYY:

EVALUATE
FILTER(
    'values',
    DATEVALUE(
        RIGHT('values'[Date_Rd], 4) & "-" &
        MID('values'[Date_Rd], 4, 2) & "-" &
        LEFT('values'[Date_Rd], 2)
    ) >= TODAY() - 730
)

hi, @Chenz55 

you can also use Now() instead of Today(). But ofcourse what ChielFaber suggested you can also use DATEDIFF to determine date differences. Here is the example code for you,

EVALUATE
FILTER(
'values',
DATEVALUE('values'[Date_Rd]) >= DATE(YEAR(NOW()) - 2, MONTH(NOW()), DAY(NOW()))
)

it should solve your issues for now. Also, please add the error message of screen shot here as well.

Do you have the error message for us? 

Regarding date filtering. I myself would suggest using the DATEDIFF function:
