## Calculate Date Difference

The goal is to create a measure of the difference between any date on the Date column and 10/01/2020. I am getting an error on the first step...not sure why the calculation is not accepting the Date field.

The final result will look something like (but with the right syntaxes):

Days to 10/01/2020  = 'Daily Trend'[Date]-10/01/2020

@diogobraga2 - Try:

Days to 10/01/2020  = (DATE(2020,10,1) - 'Daily Trend'[Date]) * 1.

Or

Days to 10/01/2020  = (DATE(2020,10,1) - MAX('Daily Trend'[Date])) * 1.

I would use datediff  https://docs.microsoft.com/en-us/dax/datediff-function-dax

ColumnDiff = DATEDIFF('Daily Trend'[Date] ), DATE(2020,01,10), DAY )
