How to calculate the difference between rows instead of between columns

[EVIJ]

Hi,

I would like to calculate the datedifference between rows, and use a calculated column for this. Is this possible in Power BI?

For example:

row 1: 4-2-2020

row 2: 8-2-2020

row 3: 15-2-2020

etc.

How do I calculate the difference in days between 4-2-2020 and 8-2-2020, between 8-2-2020 and 15-2-2020?

Thank you.

Kind regards, Ellen

@EVIJ 

you can try this

Column = 
VAR _max=MAXX(FILTER('Table','Table'[Column1]<EARLIER('Table'[Column1])),'Table'[Column1])

return DATEDIFF(_max,'Table'[Column1],DAY)

Thank you very much!! It works 🙂

@EVIJ , you can have new column like

diff =
dateduff(maxx(filter(table,[Date]<earlier([Date])),[Date]),[Date],day)
