## Difference between dates on the same line with condition.

Hello. I need to calculate the difference between the dates of different applications:

 Field Application Date P1 1st 01/01/2024 P2 1st 01/05/2024 P1 2nd 01/20/2024 P2 2nd 01/22/2024 P1 3rd 02/10/2024 P2 3rd 02/11/2024 P1 1st 02/15/2024 P2 1st 02/15/2024 P1 2nd 02/27/2024 P2 2nd 02/28/2024 P1 3rd 03/10/2024 P2 3rd 03/11/2024 P1 1st 03/14/2024 P2 1st 03/16/2024 P1 2nd 03/20/2024 P2 2nd 03/24/2024 P1 3rd 04/02/2024 P2 3rd 04/05/2024

I need a column or measure to calculate the difference in date averages from different applications of the same Field. For example, the difference between the average dates of the 2nd Application and 1st Application of Field P1, the difference between the average dates of the 3rd Application and 2nd Application of Field P1, and so on for all Fields.

Hi,

Write this calculated column formula

``Column = if(ISBLANK(CALCULATE(MAX(Data[Date]),FILTER(Data,Data[Field]=EARLIER(Data[Field])&&Data[Date]<EARLIER(Data[Date])))),BLANK(),1*(Data[Date]-CALCULATE(MAX(Data[Date]),FILTER(Data,Data[Field]=EARLIER(Data[Field])&&Data[Date]<EARLIER(Data[Date])))))``

hope this helps.
