How to format date within dax expressions

DAX Calculations
#1

I’m trying to create a calculated column which calculates the difference between two dates in two date columns (beginning and end of a task assigned to a user). The hang up is that, if the date in one of the columns reads “1/1/1900 12:00:00 AM”, I want the result to be a blank value. The system automatically displays this date when the task isn’t complete.

Here’s what I have so far (which is producing an error)

Days to Complete Task = IF(DQ_VW_Tasks[closed_at] = “1/1/1900 12:00:00 AM”, Blank(), DATEDIFF(DQ_VW_Tasks[sys_opened_on], DQ_VW_Tasks[closed_at], DAY) )

Here’s a screenshot of the column with the date I’m trying to filter out of the results.

I believe the issue is that my if statement is trying to capture a text value, when I need to capture a date value. However, I don’t know how to format the date value in the if statement. I think it’s an easy fix.

Thank you!

@Harsh Any ideas on this one?

Hi Pete,
You can change the DQ_VW_Tasks[closed_at] value to text and then compare or you can extract date , month,year,hour,minute and second part separatelty and check it with logical condition.
Please check FORMAT function is working for your requirement.
FORMAT(DQ_VW_Tasks[closed_at],1)

Thanks

Thanks @AntrikshSharma, how could I use this concept in my Dax to calculate a date diff?

I’m still not sure how to incorporate this. Thank you!

Thanks @IlgarZarbaliyev!

I’m fuzzy on how to use the format function in this function. Could you provide an example
On how this would work in a date diff calc using the column formatting in my initial post?

If you want to change the format of Date, you may do it using Format function in different ways:

For instance,
General Date = FORMAT(‘Date’[Date], “General Date”)
You may give some formats instead of “General Date”. Short Date, dd-mmm-yyyy, etc. can be used.
