Comparing two dates within different columns and rows

[Artemio]

Hi,

I have the example of data  ( screenshot of the table http://joxi.ru/xAe7W96cXNLYGm )

and I want to calculate the difference between columns "end" and "start" ( ranking is descended by the default )

For example like this http://joxi.ru/J2bkQpYtV9lXWA

Please help me I've tried a lot 😞

@Artemio , You can have new column

Date diff =datediff([start date], [enddate], day)

then create a column rank

rankx(Table, [Datediff],,desc,dense)

or

Rank Measure

rankx(allselected(Table[Date created], table[week], table[Point id]) ,calculate(Sum(Table[Date diff])) , ,desc, dense)
