## Rolling 13 month calculated up to end of previous month

I have this calculated field whcih is a rolling 13 months but I cannot figure out how to limit it to the end of the previous month

CASE WHEN `Start Date` >= DATE_SUB(DATE_FORMAT(CURRENT_DATE, '%Y-%m-01'), INTERVAL 13 MONTH) THEN 1 ELSE 0 END

The results I am looking for if I ran it today would be everything from Feb1 2017 up to Feb 28 2018

Currently it is starting at the right time but is showing dates beyond Feb 28 2018

## Re: Rolling 13 month calculated up to end of previous month

Hey @mindbender

What you'll want to do is create a filter beast mode for the card that limits the dates to not only greater than 13 months ago (what you've written) but also less than the last day of last month.

Something like this, then filter it to 1.

Case when `Start Date` <= LAST_DAY(DATE_ADD(`Start Date`, Interval -1 Month)) then 1 else 0 end

Hope this is helpful!
