## Date dimension for last 12 months

Maybe I'm atacking the problem in an incorrect way, please give feadback on that as well

I'm trying to make it easy for users of a data set to present diagrams of measures in a variation of date scales. I.E. I would like to make it easy for users to create diagrams that shows the last 6 month of data, the last 12 month of data etc

What I did was to create a new Date dimention table (Date Last 12 Months Scale) that users could use as e.g. an X-axis date matrix

The intension is that the users creating reports should be able to use the "Date Last 12 Months Scale" date dimension to create a diagram that always shows the last 12 months (or last 6 month by using an Date Last 6 Months Scale). The date Date dimention I created using: Date 12 months scale = DATESINPERIOD('Date'[Date];TODAY();-12;MONTH)

There's some problem with this method. The Date dimension is only freated when the data set is loaded. If I use daily refresh, that would not be a problem though. But the other problem is that the Date Dimension only will contain the days missing in current month. I.E. if I created the new Date table the 20'th of June, the table will only contain dates from the 20'th of July-16 to the 20-th of June-17. This is not correct as I would like to have whole months

Anyone that understands what I would like to do and have a good solution?

Try using CALENDAR function with EOMONTH.

= CALENDAR(DATE(YEAR(TODAY())-1,MONTH(TODAY())+1,1),EOMONTH(Today(),0))

This creates table with dates from 7/1/2016 to 6/30/2017.

Thanks a lot @Chihiro.

Although I slightly changed the code to: CALENDAR(DATE(YEAR(TODAY()),MONTH(TODAY())-12,1),EOMONTH(Today(),0))

This way it will be easier to change between different periods, and the year will be correct calculated anyway, no matter if I write -24, -12, or -6
