Column to Find days between dates

Hello, I am looking at traffic on a webpage and for a each page, i have a different publish date. I would like to see the number of days since the publish date for each pageview in a new column. 

 

I tried this but i cant seem to get it to work:

 

if([Date]>=DATE(2019,6,7) && ([Date]<DATE(2019,6,21))DATE(2019,6,7), DATE(2019,6,21))

  • That is the PowerQuery editor which uses an entirely different language, called M.  Your formula will look something like this.

    = if [Date] >= Date.FromText("6/7/2019") and [Date] < Date.FromText("6/21/2019") then Date.FromText("6/7/2019") else Date.FromText("6/21/2019")

    I would load it to PowerBI and do it in DAX rather than adding the column in the query editor.

  • Hello Anonymous ,

    Can you give us a screen shot of the table layout?  If you have two columns of dates in a single table [Publish Date] and [Traffic Date] you can just do [Traffic Date] - [Publish Date] in a new column to get the number of days.

      Yes that would work, but i suppose what i am trying to do is match a view date to a publish date. in pseudo code;

       

      If the "Date" is >= June 7 && < June 21, then the"publish date"is June 7th else, publish date is June 21

  • Two things, from a dax perspective you are missing a comma. The DAX below is fixed. Also, is [Date] a column or measure? Do you want your output to be a calculated column or measure? This should help direct a better answer should the missing comma not be the problem.

    Test = 
    IF(
        [Date] >=DATE(2019,6,7) && 
        ( [Date]<DATE(2019,6,21)),
        DATE(2019,6,7),
        DATE(2019,6,21))
